IDT effect on Frame and Wheels

[The_Break]

Urban legend! Frames flex less on an IDT than they do on the road. The biggest danger is from sweat damage.

complete and utter Bullsh*t

 

I tend to agree just in a more friendly manner. Your wheel take up a lot of the "stomping"/side to side flex, however when you constrain the frame at the rear axle, all of your flex is now in the frame. Creek, creek, creek. And if you get it wrong and something happens with crabon then you will wangt to eat rice crispies, snap, crackle pop!!!!

So...is that verdict - If you ride your carbon bike on an indoor trainer there's a good chance nothing will happen...but it might just crack? Great, so I have to buy/use an alu bike for IDT. That's annoying!

HAHA! Dont be fooled. All risk isn't actually 'all' risk. It's all risks that these insurance companies will pay out for, they look for any excuse to point fingures at rider neglegiblity. Using an IDT will be a great excuse for them not to pay for a cracked frame.

I think, considering that:

 

a.) No carbon frame manufacturer specifically recommends against using it on an IDT (some like Cannondale even implicitly endorse it),

b.) No IDT maker recommends against using a carbon frame on an IDT and,

c.) Large numbers of cyclists around the world successfully do it without incident,

 

the insurance company would be hard-pressed (even for them) to show that you were negligent in the unlikely event that it breaks.

Thats a good point cyclequip1, sweat accumulates a lot more on a bike on an IDT than under normal riding conditions and you need to fit some sort of protective shield to deflect the sweat. Even then it still manages find its way onto the frame and components within dripping range.

 

Obviously more of a concern on metal frames, particularly around the stem / head tube / head set region.
