We Value Efficiency As Much As You Do
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?
5 Year Warranty
The Shuriken Oversized Pulley System (TK1729S, TK1739CE & TK1729R7) comes with a 5 year warranty.
Conti-Wave machining reduces chain noise as it minimizes the contact surface against the chain.
TBT bearings are made with ceramic balls and extremely hard races for very low rolling resistance and long-lasting performance.
