November 1, 2002--Are you too fat for your equipment? According to information sent out recently by Campagnolo to its dealers, you should take extra care to check your equipment regularly if you weigh more than 80 Kg (about 176 pounds). Campagnolo's info emphasizes that there is no clear standard to say how heavy is too heavy (many other factors, such as the ability of the wheels and frame to absorb road shock come into play), but they recommend that riders over 80Kg be "especially viligant." Either that, or lay off the cakes and pies for a while . .
Interesting given all the buzz about campy vs Shimano etc.
