Hi All,
I just moved to the French alps (sucks I know!

) and did my first long descents. The roads around here have plenty of sharp bends and are up to ca. 15 % gradient which means near constant braking. After only a few 100 meters of descent my rims were almost too hot to touch.
Anybody ever experience a blowout or other problems from heating caused by braking? I am curious if I am worrying too much about it.
cheers,
Jim
