how much time
Postby jagguy » Fri Jan 01, 2010 2:14 pm
How much time can you save with quality parts for a bicycle on a time trial (triathlon) (20-40km).
If currently I have a base entry road bike with toe clips ?
It is I have read varying times for pedals, wheels frame etc

The improvements from the items which improve power transfer will depend on how much power you currently miss out on by not having them.
The improvements from the items which improve aerodynamics will depend on how fast you currently ride.
The improvements from the items which lower weight will depend on how much your bike currently weighs and how much power you can produce (F=ma).
In order to answer the question you've asked, we need you to list your weight, your bike's weight, how much power you can produce, what your current coefficient of drag is, what your bike's coefficient of drag is, what sort of road you ride on, how fast you ride now and so on.
Alternatively, I can inform you that if you add all these improvements to your bike, you will get an extra 9.5742km/h out of your bike's top speed over the length of your 22.45km commute*.
Cheers,
Graeme

Sources of improvement: priority order.
1 Tyres.
2. Tubes
3. Rims
4. Ahh it just goes on and on.
Remember to put oil on the chain.
There are so many things. Position on the bike for pedalling effectiveness. Position on the bike for aerodynamic effectiveness. Do not start worrying about weight or aerodynamics until you have got to an average speed for the leg of 40 kph.
My 2d worth.

Pedals like these - http://www.torpedo7.com.au/products/SHP ... PD-R670%29 and compatible shoes something like this - http://www.torpedo7.com.au/products/NOS ... -Road-Shoe would help transfer the power more efficiently as well.

however, a new set of wheels and aerobars will do the best for you. for most triathlon events, you can hire out TT wheelsets. they're harder riding, and have deep dishes.
anything more is superfluous; you usually dont win TT's by fractions of seconds.

Aero, aero and aero
Seriously though, your position on the bike will make the biggest difference.
Next best bang for you buck is a aero helmet and then wheels.
Weight means nothing in most tri bike legs (flat or close to) and while tyres are important, the difference is miniscule compared to the difference an excellent position will make.
Aero or die!
