Rookie question...

 

What is a good weight for a TT bike? We take +-7kg as a good weight for a competitive road bike at reasonable price. A 10kg MTB hard-tail is a very good racing weight at also a reasonable price.

 

What would a reasonable competitive TT bike weigh?

 

To make it easier...what would a top-end TT bike weigh, middle-end and lower-end?

 

Thanks!!

Weight is not the main consideration in TT\Tri bikes, aero dynamics is most important.. that being said, on a hilly course you don't want a 13kg bike to get up the hills..

my bike is under 9kgs, which is a decent weight for a TT bike

That is why I am asking ^_^ ...weight does not play such a "big" role when it comes to a TT bike, but there is a stage where you have the correct balance between weight and aero. No use you have a heavy TT bike cause your legs will feel it after a while.

I'd say the bike where you are most comfortable with being in Tri position where you can get the most watts out of your legs, ie I've seen where people have an average watts figure of 300 for a hour, but when they are in their tri position could only produce 270 watts for a hour, that means that you are sacrificing 30 watts going down low, and I dont know if the amount of drag they are reducing would make up for that in terms of avg speed.

True , you need to ask yourself 'when will it actually start making a difference"

 

Taken from Cervelo's website:

 

But where is the tipping point?

 

"Col de la Tipping Point"

 

How steep does a climb have to be before the weight savings trump the aero gains? As we saw before, the answer depends on the rider weight and speed, as a faster rider would encounter higher aerodynamic forces while the gravitational forces stay the same. For an average, 250 Watt rider, the tipping point is around a 5% slope, for a good pro who puts out 400 Watt, it’s at 8%.

We need to compare apples with apples, the poster started by saying 'Rookie question'

If you're a 'rookie' you can get away with using a mountainbike in a triathlon.

It's all relative, Not so?

Correct...Rookie question :thumbup:

 

No idea about TT bikes, I know my road and MTB. :)
