Also what makes thye difference, overall weight, rim weight etc. I guess the question "revolves" around rolling resistance / weight - some people dismiss this others swear by it - who is more correct. What are campag protons like (recreational ride around 85 kg) and what mileage could one expect from wheel like these any advice received will help gaw

A lighter wheel means that less effort is required to overcome the rolling resistance of the wheel (assuming that all tyres are equal). I believe that the lighter the wheelset, the better quality tyre should be fitted to fully exploit the advantages of the wheelset. The Campy Protons are awesome allrounders. Good distance and climbing wheels. __________________ Pain is inevitable...suffering is optional

I thought it was closer to 1g thats rotating was equal to 2g's thats static?

*wonders if taking dump would be cheaper*

cheers!

Me wonders whether a good rider on a 40km TT would be significantly faster on a $1,500 Tiagra equiped bike compared to a $5,500 Dura Ace model. Recognising that durability may play a part, are we being ripped off? Perhaps a good night's sleep and a few less Crown Lagers would have far more impact than upgrading to a new group set?
