QED Hollow Split Chainring With Featherweight Design For PES P505 P515 Power Meter Cuts Weight Without Sacrificing Stiffness For Road And Mountain Bike Rides

Featherweight Hollow 110BCD Chainring for PES P505
✔️ Hollow design trims weight but keeps stiffness and reliability

The hollow split chainring is designed for road and mountain bikes, offering a strong stiffness-to-weight balance. It uses a 110BCD 4-bolt pattern and is compatible with PES P505 Base power meters for precise power data during training or racing.

✅ 110BCD 4-bolt standard for broad compatibility
✅ Ultralight 7075 aircraft-grade aluminum construction
✅ Hollow design lowers weight while maintaining stiffness
✅ Self-developed 3rd generation tooth shape for improved shifting and longevity
✅ CNC machining for precise fit and consistent quality
✅ Static load tested to 4900 N·m for rigidity
✅ Compatible with PES P505 Base power meter and PES P505 power meter systems
✅ Weight: 138 g for the larger chainring

💡 What is a hollow chainring used for in road and mountain biking, and how does it work with power meters?

Hollow chainrings trim weight while preserving stiffness, helping riders ride lighter and capture accurate power data with a meter.
