*The shifting is as good as with the original Dura Ace cage.
*It’s more aero than the OEM cage and other oversized cages.
*It saves more watts than other cages
*One of the lightest oversized cages on the market.
*First mono plate construction of its kind.

STIFFER GUIDE PULLEY, NOT CAGE, MEANS BETTER SHIFTING.

Many companies try to convey that a stiffer cage is a better shifting cage. But the single most important factor that impacts the shifting is the upper pulley itself. Since the upper pulley is mounted directly to the rotating pivot axle, the flexibility of the cage plays very little role. It’s the upper pulley that moves the chain left and right enabling gear change, so making the upper pulley really stiff allows for greater shifting precision. Most oversized pulley cage systems use very small bearings, with a lot of lateral play at the teeth which in turn provide poor, sloppy shifting. HOLLOWcage®, unlike other pulley cage systems, use abnormally large, bespoke, full ceramic bearings that make the pulleys incredibly stiff. Lower bearing alone is actually big enough to fit 11T pulley inside of it.
