No - Wahoo Speedplay pedals are not user-serviceable. Pedal disassembly is not advised and will void the product warranty.
Wahoo Speedplay pedals have an updated design with triple sealed needle/cartridge bearings that do not require additional grease and a revised pedal body (steel ring encircles the whole pedal surface) for increased durability. The respective components are designed to last the full life of the pedal without incremental service.
If you're having trouble with your Wahoo pedals, please submit a support request for in-depth troubleshooting, repairs, and replacement.
