WHY USING OVERSIZED PULLEY WHEEL CAGE-Upgrade your drivetrain for ultimate efficiency and superior performance.KCNC Wheel Bearings reduce friction, which gives you a lower rolling resistance.Upgrading your wheel bearings to oversized pulley will maximize the return you get from your energy.

THE EFFICIENCY OF OSPW-The Oversized Pully Wheel(OSPW) system reduces friction in the pulleys by 45 % and for your optimised performance.The overall power savings of the OSPW System reach 30%-60%, or more in some cases, over a stock setup.

NARROW WIDE PULLEY&DURABLE CHAIN RETENTION-The OSPW for SRAM Eagle Mechanical features a narrow wide tooth profile to ensure durable chain retention.The system consists of Top 14t & Bottom 16t alloy pulley wheels fitted with low friction bearings and a lightweight cage made from 7075 Alloy.Coated bearings prolong the lifetime even further.The oversized pulley wheels have 3-5 times longer lifetime than the commonly used standard pulleys on the market.
