Tacx

Shimano 9/10 Stainless Derailleur Pulleys

Benn having drive train issues. Noticed der jockey wheels worn to nubs. *Wow* - no one in my group of DH/FR friends had ever had a deralleur last more than 10 months (DH in VERY rocky terrain), so I'd NEVER encountered this issue before! This Shimano Shadow sits so close to the frame that It's lasted YEARS. So these jockey wheels fixed the problem for a mere $20!

Good quality set of pulleys, snd a huge improvement over the Shimano factory set. Absolutely worth the upgrade. My only minor gripe is the lack of documentation. Installation tip: Tacx provides multiple plastic shim sets to properly space the pulleys in the cage, but you either need to do trial and error to get the right fit - or remember to keep your old pulley assys and measure their total width with a caliper :-)
