I'm looking to upgrade the wheels on my Felt bicycle. So far these look to be the best value since they are REALLY light for the money. I can get them for $220 at a local bike shop that does internet sales as well. Is this a good choice? I am 170 lbs if that matters. The wheels I have right now are very heavy. It is just hard to find info on these wheels...no one i know has heard of them???
