SHURIKEN Oversized Pulley System For Shimano Dura-Ace, Ultegra Zenith

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 TBT bearings inside the pulleys are filled with specially developed light grease to keep drag low to minimize drag. The carbon fiber cage and hardened steel / dura-aluminum hardware creates a light and strong foundation for the system. The pulleys are made of dura-aluminum and PVD (Physical Vapor Deposition) coated for long-lasting low friction and clean aesthetics. A purpose-specified tooth profile ensures crisp shifting and super smooth running. Upgrading to the Shuriken oversized pulley system allows you to add drivetrain capacity to a short cage derailleur, enables running a larger cassette with expanded gear range. Ride easier and longer with the Shuriken oversized pulley system.

Thanks to its 13-19 tooth pulley size, a longer B screw is not needed. When properly installed and assembled, the Shuriken pulley system will improve the efficiency of any drivetrain.

SHURIKEN Oversized Pulley System For Shimano 105

We all know that rear derailleur is the key component which differentiate drivetrain performance the most, the best shift precision and durability can only be found on the very top model regardless of their generation. The new Shuriken TK1729R7 is designed to brake the rule, it brings not just efficiency here – it also dramatically improves the shifting precision and durability, thanks to the smooth bearings and purpose-specific tooth profile that can be found on all Shuriken pulleys. 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, sounds interesting?
