Experience smoother and more efficient shifting with the CeramicSpeed OSPWX System Coated Shimano XT/XTR 12S Pulley Wheels. Engineered to reduce friction by 35-40% compared to standard pulley setups, this system delivers noticeable performance gains for serious riders. The lightweight, custom molded carbon fiber cage ensures exceptional durability while maintaining the same chain length as stock pulleys, making installation straightforward without compromising your drivetrain's geometry.
The precision-designed 14-tooth upper and 18-tooth lower pulleys provide stable chain retention, minimizing drag and maintaining consistent tension across varied terrains. Crafted with premium aluminium and ceramic-coated bearings, these components offer both resilience and smooth operation. Developed and handbuilt in Denmark, the OSPWX System is globally tested to meet the demands of 12-speed Shimano XT/XTR off-road drivetrains.
Included in the package is the complete OSPWX System tailored for Shimano XT/XTR 1x12, along with CeramicSpeed Pulley Oil and a sticker sheet to personalize your setup. Compatible with Shimano XTR M9100-SGS, XTR M9100-GS, and XT M8100-SGS derailleurs, and supporting cassette ranges up to 10-51, this upgrade is perfect for riders seeking to maximize drivetrain efficiency and reliability.
Will these pulley wheels fit my Shimano XT M8100 derailleur?
Yes, the OSPWX System is fully compatible with Shimano XT M8100-SGS derailleurs, designed specifically for 1x12-speed setups.
Do I need to change my chain length when installing this system?
No, the OSPWX System maintains the same chain length as stock pulleys, so no chain adjustments are necessary.
