The Black Inc THIRTY wheelset is the embodiment of an ideal lightweight climbing wheel. With a low rotating mass, it provides immediate acceleration as the grade points skyward, and a broader rim profile increases stability to carve through descents.
Black Inc THIRTY's newly developed rim shape is CFD-certified for improved stability when using wider than 25mm tires - creating a rarity for riders seeking enhanced traction, handling and comfort. The THIRTY's profile is optimized for 28mm or larger tires.
A proprietary textured brake track provides an 8% braking performance increase in dry conditions and a 13% increase in wet conditions.
