where do you look to find out about Tg of a particular material? Can you provide a link, because all I'm getting is retailer websites.


Also, is it true that you should change brake pads when you switch between carbon and aluminum wheels? my friend told me you don't want the aluminum particles to go into the carbon wheel brake pads, which doesn't really make any sense to me, because the brake lining on the wheel has nothing to do with what the wheel is made of. Also, what is the braking surface made of? I think I read somewhere that the braking surface also has a Tg, which to me suggests that it's a layer of polymer deposit.



and as it's been sort of mentioned, I wouldn't worry about the stiffness of the wheel giving a harsher ride. The tires are a much bigger contributer to riding comfort. And isn't carbon much better at absorbing shock than aluminum?

but then again, I wouldn't get carbon wheels if I wasn't racing.
