Not all carbon wheelsets have to cost an arm and a leg. Case in point are the Roval Control 29 Carbon mountain bike wheels. Using techniques learned while developing the SL iteration of the Control 29, these wheels are able to produce the lightweight XC performance you need at a more attainable price. Don't confuse "value" with a degredation in performance, however, as these rims have much of the same features found on the SL, like the Zero Bead Hook design. This allows for continuous fiber layup across the sidewall and rim bed, resulting in stronger impact resistance. You also get DT Swiss hub internals at the rear hub for quick engagement and acceleration and the attention to detail that only hand-built wheels can provide.
