What Our Gearhead(R) Experts Are Saying:"These have been on my training bike all season and the difference shows most on long climbs where every gram actually matters. They stay composed on the descent too, which you don't always get from a wheel this light."The 202 NSW is built around a carbon layup that does two things most lightweight rims ask you to trade off against each other. It stays stiff where the spokes attach and tough where the tire sits. The result is a sub-1100-gram wheelset that holds up to the road without asking you to baby it on the descent.
