Q & A

Was sind die ersten Upgrades, die man für ein Zeitrennenrad machen sollte?

Die ersten Upgrades sollten Reifen sein, da sie den einzigen Kontakt zum Boden haben und schnelle Reifen ständig wirken. Sie sind auch eine relativ günstige Option und werden sowieso regelmäßig ersetzt werden müssen.

Welche Reifenbreite sollte man für sein Rad wählen?

Man sollte die Reifenbreite so wählen, dass sie der Breite des Rades entspricht. Die Regel von 105 besagt, dass die Reifenbreite 105% der Radbreite sein sollte.

Was sind die Vorteile von Latex- oder Tubeless-Reifen?

Latex- und Tubeless-Reifen bieten eine schnellere Rollwiderstandsperformance im Vergleich zu herkömmlichen Butyl-Reifen. Sie sind zwar etwas teurer, bieten jedoch einen besseren Reifenschutz und sind für Zeitrennen besonders geeignet.

Wie kann man die optimale Reifendruck bestimmen?

Man kann den optimalen Reifendruck mithilfe eines Silica-Rechenwerkzeugs ermitteln, das im Internet kostenlos verfügbar ist.

Warum sollte man die Kette mit Wachs behandeln?

Eine mit Wachs behandelte Kette ist schneller und erfordert weniger Zeit für die Reinigung. Sie hält auch länger an und bietet einen Vorteil bei der Langzeitnutzung.

Was sind die Vorteile von Aerobars?

Aerobars bringen den Körper und die Brust aus dem Wind heraus und platzieren den Radfahrer in einer komfortablen, aerodynamischen Position, die er über die gesamte Strecke aufrechterhalten kann.

Was sind die Vorteile eines Wachs-Chain-Lubrikanten?

Ein Wachs-Lubrikant reduziert die Reibungswiderstände und verlängert die Lebensdauer der Kette. Es ist auch einfacher zu reinigen, im Vergleich zu nassen Schmierstoffen, die bei Rennläufen Verschmutzungen aufnehmen können.

Was sind die Vorteile eines Zeitrennen-Helms?

Ein Zeitrennen-Helm bietet erhebliche aerodynamische Vorteile, da er den Windwiderstand reduziert. Er passt sich der Position und der Körperform des Radfahrers an und hilft, den Luftstrom über den Rücken zu leiten.

Was sind Aero Socken und was bringen sie?

Aero Socken sind spezielle Socken, die über dem Schuh angezogen werden und einen aerodynamischen Muster auf der Seite haben. Sie halten den Luftstrom an der Wade an und reduzieren den Luftwiderstand.

Was sind die Vor- und Nachteile von tiefenprofil-Rädern?

Tiefenprofil-Räder bieten aerodynamische Vorteile, da sie weniger im Wind auftreten und somit weniger Luftwiderstand erzeugen. Ein Nachteil ist jedoch, dass sie anfälliger für Seitenwinde und Seitenkräfte sind.

Was ist ein aero-Wasserflasche und was bietet sie?

Eine aero-Wasserflasche ist eine schlanke und aerodynamisch gestaltete Flasche, die anstelle einer runden Flasche den Luftwiderstand reduziert. Sie ist oft an der Unterseite des Rades integriert oder kann auch als zusätzliches Zubehör erworben werden.

Was ist der Vorteil eines Powermeters?

Ein Powermeter hilft, die Anstrengung im Rennen besser zu steuern, indem es eine konsistentere Leistung ermöglicht. Dadurch kann die durchschnittliche Leistung im Rennen gesteigert werden.

Was sind die Vorteile von Windkanaltests?

Windkanaltests ermöglichen es, die aerodynamischen Eigenschaften des Radfahrers und seines Fahrrads zu optimieren. Es können verschiedene Positionen, Reifen und Räder getestet werden, um die schnellste Konfiguration zu finden.

Was sind Aero-Armlehnstangen und was bringen sie?

Aero-Armlehnstangen sind Armlehnstangen mit einer speziellen Form, die den Luftstrom besser um den Arm lenkt und weniger Luftwiderstand erzeugt. Sie können dazu beitragen, die Geschwindigkeit zu erhöhen, sind jedoch auch teuer und erfordern möglicherweise Windkanaltests, um ihre Effektivität zu überprüfen.

Wie kann man die Aerodynamik des Fahrrads verbessern, indem man Kabel versteckt?

Indem man Kabel hinter der Armlehne oder an anderen unsichtbaren Stellen versteckt, kann der Luftwiderstand reduziert werden. Jede cm Kabel, die versteckt werden, kann据说 einen Luftwiderstandsverlust von etwa einer Watt reduzieren.

Keywords

💡Time Trial

Ein Zeitfahren (Time Trial) ist eine Disziplin im Radsport, bei der die Fahrer einzeln starten und gegen die Uhrzeit fahren, um die beste Zeit zu erzielen. Im Video geht es darum, wie man sein Zeitfahren-Rad und seine Ausrüstung optimiert, um schneller zu sein. Das Video diskutiert verschiedene Upgrades, die man vornehmen kann, um die Leistung zu verbessern.

💡Upgrade

Ein Upgrade bezieht sich auf die Verbesserung oder Aktualisierung eines Teils oder einer gesamten Einheit, um eine bessere Leistung zu erzielen. Im Kontext des Skripts bedeutet dies, dass der Sprecher verschiedene Komponenten und Aspekte des Zeitfahren-Rads und der persönlichen Ausrüstung verbessern will, um die Geschwindigkeit zu erhöhen.

💡Reifen

Reifen sind der einzige Punkt des Kontakts zwischen dem Rad und dem Boden. Im Video werden Reifen als erstes Upgrade genannt, da sie eine entscheidende Rolle bei der Rollwiderstandsreduzierung spielen und da sie eine preiswerte und veräußerliche Option darstellen, die ständig ersetzt werden muss.

💡Rollwiderstand

Rollwiderstand bezieht sich auf die Kräfte, die entstehen, wenn ein Rad auf einer Oberfläche rollt. Im Video wird auf die Wichtigkeit von Reifen hingewiesen, die einen niedrigen Rollwiderstand haben, um die Geschwindigkeit im Zeitfahren zu erhöhen. Eine Website, die Tests durchführt, wird in der Videobeschreibung erwähnt.

💡Rim

Der Rim ist der äußere Teil eines Fahrradrades, auf dem die Reifen montiert sind. Im Video wird betont, dass die Reifenbreite der Breite des Rims angepasst werden sollte, um den besten aerodynamischen Effekt zu erzielen.

💡Inner tubes

Inner tubes sind die luftdichten Rohre, die in den Reifen eingebettet sind, um die Reifen aufzublasen. Im Video werden Latex- oder tubeless-Systeme als schnellere Optionen für Zeitfahren empfohlen, da sie weniger Rollwiderstand haben.

💡Reifendruck

Reifendruck ist die Luftmenge in einem Reifen, die den Druck bestimmt. Im Video wird der richtige Reifendruck als wichtiges Upgrade hervorgehoben, da er den Rollwiderstand beeinflusst und somit die Geschwindigkeit im Zeitfahren verbessern kann.

💡Geschwindigkeit

Geschwindigkeit ist die Messung der Distanz, die ein Objekt in einer bestimmten Zeit zurücklegt. Im Video ist die Geschwindigkeit ein zentrales Thema, da verschiedene Upgrades und Techniken besprochen werden, die darauf abzielen, die Geschwindigkeit des Radfahrers im Zeitfahren zu erhöhen.

💡Aerobars

Aerobars sind eine Art von Stützpunkten, die verwendet werden, um die Aerodynamik und den Windwiderstand beim Zeitfahren zu verbessern. Im Video werden Aerobars als wichtiges Upgrade für die Positionierung des Körpers im Windkanal empfohlen.

💡Widerstandskoeffizient

Der Widerstandskoeffizient (CdA) ist eine Kennzahl, die den aerodynamischen Widerstand eines Objektes gegen den Wind misst. Im Video wird erläutert, wie man durch die Anpassung der Körperhaltung und die Verwendung von Aerobars den Widerstandskoeffizienten reduzieren kann, um schneller im Zeitfahren zu sein.

💡Zyklen

Zyklen beziehen sich auf die wiederkehrenden Bewegungen oder Prozesse. Im Video wird die Bedeutung von regelmäßigen Zyklen wie dem Wechsel der Reifen oder das Aufwenden von Zeit für die Positionierung und die Wahl der richtigen Ausrüstungsteile hervorgehoben, um die Leistung im Zeitfahren zu optimieren.

💡Windkanal

Ein Windkanal ist ein Labor, das verwendet wird, um die Aerodynamik von Objekten zu testen. Im Video wird als eines der teuren Upgrades die Windkanalprüfung erwähnt, bei der die Aerodynamik des Radfahrers und seines Fahrrads optimiert werden kann, um die Geschwindigkeit zu erhöhen.

Transcripts

upgrading your time trial bike it could

be hell of a lot of fun but more

importantly it can make you faster this

got me thinking however if I was going

to upgrade my bike and my stuff from the

beginning which order would I do them in

I have for you 21 of the best upgrade

that you can do for your time trial bike

we are going to go from the essential to

the purchasable to the reaching for it

and for each item in this list I'm going

to have an estimated watt saving in the

corner for you to look at but this

estimation is going to differ from

person to person and bike to bike it's

just a rough range so with that let's

start with the essential come on in for

me easily the first upgrade I'll do on

any bike

is tires

the reason being it's your only point of

contact with the ground and fast tires

are going to work literally all of the

time they're also a pretty cheap upgrade

to do as well and they're more of a

perishable so you're going to be

replacing them at one point or another

anyway an easy way to find the fastest

tires for your bike is a you've got to

start a bicycle rolling resistance these

guys do all the testing for you and I

will link to their website down below

the second thing to note of tires is

that you want a tire width that's going

to fit the width of your Rim so

realistically you here you want to be

following the rule of 105 so your wheel

width is 105 the width of your tire for

upgrade number two we're going to be

sticking around the tire area and we're

going to be upgrading the inner tubes

for me if you're time trialing you've

got to go to the quickest options

available and that's either tubeless

like I'm running here or latex latex

inner tubes don't actually cost that

much more than a normal butyl in the

tube or even a TP YouTube but if you

want more rolling resistance data bike

rolling resistance I've done it again

another link down below okay I promise

we are nearly done with wheels but my

next upgrade is going to be your tire

pressure and the reason it's number

three is that you may have the fastest

tires you may have the fastest inner

tubes but the pressures need to be right

as well and it's something that you can

just do for free really quick right

before you're setting it up and an easy

way to find out your optimal tire

pressure is to just go to the silica

calculator linked below again free to

use and you can find your perfect tire

pressure

number four if you are serious about

going fast the next upgrade has to be a

waxed chain at the moment wax is easily

the fastest chain that you can do and it

just saves you so much time on cleaning

your chain not only that it's gonna last

longer as well if you want to actually

look at some test data to how much

better a wax chain is I'm going to have

zero friction cycling linked below as

well another link to you to follow but

in all seriousness if you use a wet Lube

on your race chain then contamination is

going to get on the inside the process

to clean out 100 of that contamination

takes forever that's why wax Shane is

more advantageous it will be faster all

the time every time for my fifth and

final of the essential upgrades that you

can do for your time trial bike is your

position if you're using a road bike

aerobars are amazing what they tend to

do for you is they bring your body and

your chest out of the wind and it puts

you into a comfortable aerodynamic

position that you you can hold the whole

way around the game seen on this one are

massive there are lots of things that

you can work on such as getting your

elbows narrower your head lower and this

just makes your frontal area smaller so

your front is hitting less wind you may

have heard some people talking about CDA

the CD is coefficient of drag the a is

the area and this reduces your area

other top tips would be to shrug the

shoulders and Tuck the head down and

this just helps keep the area of your

body small to the wind I'm just here

afterwards in the editing booth and

there is one essential bonus tip that

I'm gonna I've missed out on the video

somehow and this one is shaving your

legs for some of you this might sound

silly but honestly if you want to go

faster it's genuinely a massive massive

saving a lot of people have tested this

as well gcn have tested it gtn have

tested it and even specialized In Their

Own Wind Tunnel have tested as well and

they're kind of seeing measurements

anywhere from five watts to a 20 watt

saving especially if you're as hairy as

I am I'm like a gorilla then you're

going to see some big big savings on the

bike just from shaving your legs bonus

tip

the reason I've chosen those as my first

five and the essential upgrades you must

do is because they work all of the time

doesn't matter what you're doing how

fast you're going how far into the event

you are how much power you're pushing

those upgrades work now that we have

done the essential we're going to go to

the purchasable and we're going to begin

with number six on my list and that is

the bike itself a time trial bike the

reason I have the time truck bike so

high up on the purchasable list is

because of the comfort and the

adjustability that it provides yes the

bike itself is much more aerodynamically

shaped and this saves usually like five

to ten what so it is a big saving in

itself but the real gains come from it's

what it does to you as a person so the

seat tube here tends to be at a steeper

or more vertical angle that opens up

your hip angle a lot more allowing you

to produce more power then the cockpit

itself is usually a lot more adjustable

and that's where most of the upgrades

have come in these past 10 years for

time trial bytes not on aerodynamics but

on adjustability to fit your body

nowadays you can actually find a lot of

cheap time trial bikes on Facebook

Marketplace or Ebay they are generally

the rim brake versions of brakes I

personally prefer disk because it opens

up the wheel shape and the freedom of

the tire but even if you do go for a rim

brake option they're still fantastic and

they still get you into a great position

number seven on my list is actually a

time trial helmet in terms of bang for

your buck this is actually probably one

of the best upgrades that you can do the

Aero savings are massive but there are a

few things you should know before you

get one the first thing being is that a

time trial helmet fits your position and

your body shape the idea or how a time

trial helmet works is basically the wind

hitting the front of your head is going

to be taken over the back and the reason

this tail is on here is so the airflow

can attach onto your back this will

create less weight behind your body and

decrease the amount of drag that you're

creating in terms of bang for buck this

is a big winner in my book and following

on from wearables my next upgrade is a

proper skin suit a one-piece suit

designed for time traveling this comes

in at number seven just because it's

another great bang for buck upgrade I

mean this one from no pins costs about

160 pounds and it's probably as

aerodynamic as you can get just having a

piece of clothing that doesn't crinkle

or fold and has all these patterns on

them to keep airflow attached to you

it's a massive massive upgrade if you

really want to take this one seriously

then you can also go for the under top

as well which has big trip flows on the

arm and this will trip even more flow

around the body and help smooth out the

airflow keeping you even faster coming

in at number nine is another bang for

buck upgrade and these are Aero socks

these are basically socks that go over

your shoe and they also have a nice

pattern on the side of them as well

because your legs are cylinder these

kind of almost work like a golf ball

once again keep an airflow attached

around the leg decreasing the amount of

drag as there's less weight left behind

your leg and whilst these cost around 50

60 pounds the what saving can actually

be surprisingly high so a super nerdy

one but one that I really like number 10

on the list

Wheels I'm sure some of you have been

waiting for this one when are the wheels

come in Jace well they're coming at

number 10 because they're quite an

expensive upgrade there are other things

that you can do such as the Aero socks

that almost provide as much benefit as a

deeper section will that being said

though deep section wheels are great

they work all the time and they do

actually make you faster more

importantly for me though they probably

look a lot cooler than if you want to go

extra extra serious I have a disc wheel

right here and disc wheels are the

fastest kind of wheel that you can buy

especially for the rear but for me it is

a later upgrade because of the cost of

it if you do want to go cheap however

you can kind of fashion your own one

which gtn have done or there's another

option that you can just buy they're

called easy disk linked below and this

will give you a fully fared rear wheel

for very cheap about 160 pounds the what

there are risks to going deeper on the

wheels and that is your more susceptible

to sidewinds and side force from the

winds but for me it's a small price to

pay for Speed and looking good coming in

at number 11 on my list is I think is a

great one and that is actually an aero

water bottle a lot of new bikes nowadays

actually come with them integrated such

as this obey or do there's the new

colnago that Teddy pigata rides and the

canyon Speed Max which has integrated

storage in the down tube here you don't

need to buy them integrated you can just

buy ones that look very similar to this

nice and slim and they usually cost

around 25 to 30 pounds rather than a

circle hanging out behind a tube it's

basically deepens the shape of your down

tube here this one's here because it's

cheap but it works number 12 is kind of

a free one that you can do and that's

actually a bearing check especially if

you have an all the time trail bike with

your chain off for example when you're

waxing your chain just check all your

pulley wheels are spinning nicely the

rear hubs spinning nicely your your

bottom bracket is spinning nicely it's a

small thing that you can do but it's

just going to keep on top of those

bearings make sure you're not wasting

any Watts it's not going to gain you

much but it's not going to waste any I

am going to talk more about bearings

later though my final purchasable

upgrade is actually going to be a power

meter you can either do this with a

crank or you can do it with the pedals I

have a pedal option here I've got the

favera aseomas but just having a power

meter is really helpful for managing

your effort by holding a more consistent

power you could potentially hold 5 to 10

watts more average than if you went too

hard at the start so just by power

management you can actually upgrade your

time trial speed with a power meter

staying on the pedals if you want I know

Wahoo Speed play do a much more

aerodynamic pedal and I know it can save

yeah like one to three Watts but for me

I don't know if that's worth upgrading

for well those are my purchasable

upgrades now let's go on to the more bar

reaching upgrades these upgrades are

upgrades that probably cost more than

what they give back although also just

some very fine finishing touches that

you can do to you and your bike so that

brings me on to number 14 taping holes

as you can see around the top here I've

taped up some holes which basically

would have Disturbed the airflow a lot

more and I've done this in other areas

of the bike for example there's a hole

here to be quite honest I'm not sure how

much taping these holes actually save

but if you have a lot of them on your

bike then I think they could add up to a

significant number like maybe like two

maybe three watts and it's something

that's so cheap I mean most people just

have some electrical tape lying around

and it's a pretty damn easy job to do 15

on my list is actually much more UK

specific in the UK when it's rear and

front lights on a bike and I just think

you could be smart with the position

that you put them in for example I have

this nice undersaddle one here the

airflow should be pretty much blocked

all the way from this point forwards

anyway so having a light here shouldn't

impact it at all on my front light here

I've gone for a different option I've

simply glued a magnet underneath my

Garmin holder and I can just pop the

lights off and on it never comes off but

it's very small and it kind of sits just

just below my hands so it should be in a

good position to be out of the wind but

still visible coming in at number 16 is

a one by drive train by making a bike

one bite you can you basically remove

your front derailleur and doing this

gives you an aerodynamic Advantage

because there's a lot less Mass here

hitting the wind and there's also not

another chain ring on the inside also

hitting the wind when people go one by

they tend to go for a bigger chainring

and what that does if you're going

really fast then instead of your chain

cross training you're more likely to be

on these middle cogs so there's a

straighter train line going through the

bike and this can save anywhere from

like one to four Watts depending on your

chain there are some downsides to this

one though and that is less gearing if

you're on more of like a hilly time

trial course and you might need to go

into the small ring I think this would

disadvantage you and then you're

probably more likely to be cross

training even more if you go for a one

by setup so it is a bit course specific

to one bite speaking of that bigger

chainring that could be upgrade number

17. the bigger chainring allows for Less

articulation around the chain so it will

give you a very very marginal save and

what's from that but its main purpose is

to give you a straighter chain line

again so once again the bigger chainring

is very core specific so if you know

you're only doing pancake flat courses

and you push a lot of power you're going

to be in those top three teeth for a

long time then the Big Chain ring could

be more beneficial if you're not very

powerful like me you can stick with a

smaller one if you do go to a bigger

chainring there are options for more

aerodynamic ones luckily this is the one

the one that came on the bike for me but

as you can see it's just a fully Fair

chain ring which should in theory be

more aerodynamic upgrade number 18 would

be an oversized pulley wheel so this

here is a normal size but with an

oversized you would have a much bigger

pulley wheel around here what this does

it reduces the art articulation of the

chain and the less the chain has to

articulate the less power you have to

produce to overcome friction forces

within the chain this one however is a

very very expensive upgrade for very

very minor Watts I've also heard some

disadvantages to going up to the

oversized pulley wheel and that could be

from the bearings a lot of them have

ceramic bearings which need more

frequent maintenance and if the bearing

friction is costing you more watts than

the articulation friction then well it's

a downgrade in a sense if you go for the

oversized pulley well so if you're going

to do it make sure you keep on top of

the bearings speaking of oversized

pulleys and ceramic bearings upgrade 19

could be that you upgrade all of your

bearings to ceramic you can see the

bottom bracket the pulley Wheels the

wheel hubs themselves like I said there

may be more maintenance involved but

this can make you a little bit faster

some people even go to the levels where

they clean out all the original Grease

in their bearings and they just put like

a really really fast racing in Greece

the race in Greece doesn't last as long

or protect the bearings from water as

much so you will probably wear through

those bearings quicker but it's just

another option I've only got two more

upgrades with one I guess bonus upgrade

at the end if you can find a way to do

it becoming it at number 20 is wind

tunnel testing this is where we get

really expensive but if you're super

super serious you can't think of any

more games you can go to a wind tunnel

and the guys there will probably help

you find those teeny teeny little

margins and that could potentially add

up to some really massive gains they can

adapt your position they can change

things on the bike they can look at

different tires different wheels and

they can see what's actually faster for

your bike for upgrade number 21 I am

going to give you Aero Aero bars another

very expensive component to do if you

don't know what Aero Aero bars are

they're basically Aero bars but they

have much more of a fairing around them

and they're designed to be shaped around

your all these can be more comfortable

for you and they can direct more flow

around the arm rather than being more

awake and dragged behind the arm this

can give you a minor saving especially

if you get the till to the right

position but I'll probably recommend

some wind tunnel testing if you are

doing this to see if they are faster for

you this one is very expensive and I

think it is very far-reaching if you're

going for that upgrade then finally my

bonus upgrade I guess is going to be

number 22 but that is to hide as much

cable as you can I've got mechanical

groups out here so I have to have these

cables coming through here unfortunately

I won't go through my monorizer older

bikes tend to have much more cables

hanging around the front so there's

options you can tie them together you

can potentially hide them behind

something just things to get the cables

out the way I think I heard a stat once

for every 10 centimeters of cable it's a

one watt loss wow okay that list was

exhaustive and there was a lot on there

if there's any more in this video video

that I haven't thought of please let me

know but I'm Jason this has been cycling

unboxed and I look forward to seeing you

in a future video

[Applause]
