Shuriken Oversize Pulley System for Shimano 105

R3,350.00

The Shuriken oversized pulley system is engineered to be the best. It is designed to increase drivetrain efficiency of any bike. Larger pulleys reduce drivetrain friction not only because they spin at lower RPM, but also less chain articulation angle. The TBT bearings inside the pulleys are filled with specially developed light grease to keep drag low from the beginning.

Description

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?
