Token Shuriken Oversized Pulley System For Shimano 105
The Shuriken oversized pulley system was engineered for maximum performance and designed to increase the efficiency of the drivetrain on any bike. The larger diameter of the pulley allows the oversized pulley system to rotate at lower RPM and reduces the articulation angle of the chain, lowering drivetrain friction.
The bearing in the top pulley which spins faster is TBT ceramic, adding smoothness to where really matters. It's even lighter than a stock long cage with plastic pulleys.
