Edge Composites 45 Clincher Rim
If versatility is your primary goal, Edge Composites' 45 Clincher Rim, which uses a standard cycle tire (called a clincher) that's held in place by pressure from the inner tube, is hard to beat. The 45 Clincher has a better blend of aerodynamics, stiffness, weight and durability than most composite clinchers, with a 45mm rim profile that minimizes drag and weighs just 397g. The 45 Clincher Rim can handle punishing training rides and hold its own in competition. It has a carbon braking surface that dissipates heat and a spoke interface that reduces fatigue and prolongs wheel life. If you can only afford one set of rims, the Edge Composites 45 Clincher is worth a look.
Reynolds SDV66C Clincher and SDV66T Tubular Rims
According to wheelbuilder.com, the Reynolds V66C and V66T were designed to be the lightest, most responsive and fastest rims available. Their unidirectional, one-piece carbon fiber construction delivers excellent rigidity and torque and a scrim layer in the braking surface eliminates vibration for smooth, reliable stops. These rims are favored by racers and the National Advisory Committee for Aeronautics (NACA) says their airfoil shape has an optimal drag coefficient.
Zipp 720 Clincher and 620 Tubular Rims
Zipp's 720 and 620 rims are wind-tunnel tested to maximize aerodynamics. They're designed for TT riders and triathletes who want non-disc rims with better aerodynamics and speed than the competition. Dimples and a patented toroidal shape give these rims better wind-slicing performance than other deep profile designs. They also have a ceramic surface for confident braking and Carbon Bridge technology for enhanced durability.
Ritchey Carbon SuperLogic Tubular Rim
At 260g per rim, the SuperLogic Tubular mountain bike rim is lighter than many road bike rims and the lightest MTB (mountain bike) rim on the market, according to bikerumor.com. Ritchey uses a "disappearing" mold to eliminate the internal bladder that adds to the weight of other rim manufacturers.
Edge Composites 29er XC MTB Clincher Rim
The 29er XC sets a new standard for lightweight yet rigid MTB Clincher rims. Wheelbuilder.com says it's "the fastest-rolling, off-road wheel in the world." The 29er XC is also one of the lightest 29-inch rims you can buy and its reduced rotational weight gives riders an edge during technical ascents.
