The OSPW X ALPHA is built for gravel, designed for SRAM's 13-speed XPLR AXS E1 rear derailleurs, with ALPHA pulleys that keep grit and mud away from the bearings.
Why oversized?
Larger pulley wheels mean the chain bends less as it wraps around them, which cuts drivetrain friction. Combined with CeramicSpeed's hand-built hybrid ceramic bearings, an OSPW system is one of the most effective drivetrain upgrades you can make.
ALPHA technology
- ALPHA Disc pulleys with patented ADR (Active Debris Remover): stainless dust shields and a bladed groove that pushes contamination away from the bearing
- Hand-built hybrid ceramic bearings
- Injection-moulded carbon cage
- Hand-built in Denmark with a lifetime warranty
Available from The Cycle Collective in Dorking. Our workshop can fit and set up your OSPW system.
