A couple of weeks ago, just after having the wheels of my Bianchi(32 sp lightweight rims on 105 hubs) trued for the second time in just a couple of hundred miles, I rode a 32 mile ride and the wheels were out of round and warped.
I've read many threads here about trouble with different wheels, but haven't had a problem in the past with my older bikes, and I thought that even at close to 260, the 32 spoke wheels would work fine.
Anyway, the next day Nashbar had a sale on the Vuelta Corsa HD wheelsets....and free shipping. After reading the reviews, I ordered them.
Are they heavy? Yes they are. Are they true like an arrow after riding all weekend? Yes they are. Can I tell a difference on hills? No I can't, I still pant and wheeze and look on the pavement for my lungs. Is Karl glad he ordered them and had a fantastic ride? Damn skippy.
