Racing Spec 2.2 ULTRALIGHT


The PB Breaker

CARBON FIBER TUBULAR WHEELSET

Limited Availability



The Racing Spec. 2.2 ULTRA LIGHT is built for riders whose aim to push their riding records to the extreme, claiming KOMs and breaking the impossible to break personal bests. Rotating weight requires 2-3 times more watts to accelerate than static weight.  By significantly reducing the weight on the wheels to around 850 grams per set, a lot energy will be saved from propelling the mass of the wheels, and therefore more watts will be directly transferred toward forward acceleration. RS 2.2 UL is feather light, yet the structure is solid.  It is put together with Italian’s lightest – Extralite Cyber hubs (48 g front/ 129 g rear), Belgium’s finest – Sapim aero blade spokes, and TORZC SL Extreme Light Weight Formation carbon rims.  The carbon rim and the spokes are connected by internal nipples that is able to reduce stresses on the conjunction points and also decreases overall wind drag creating aerodynamic benefit. Inherited the rolling smoothness from its first generation predecessor. Improved stability in aggressive cornering, overall handling, and comfort with the new 25 mm wide aero carbon rim design. If you are serious rider planning to claim KOMs or breaking personal records on climbs, Racing Spec 2.2 ULTRA LIGHT is the wheel for you.
