Stone Design Workshop established in 2014, focus on high quality bike chainring design and manufacture. We covers full range BCD and direct mount and tooth 22T to 70T.
The innovative design and high precision processing CNC center is our advantage. Long lasting lifespan up to 20,000km, we win professional riders favorite in worldwide.
Design by our own team.
All CNC center from China Taiwan. Process precision 0.03mm.
High standard quality check.
Aluminum 7075 T651 from USA Aleris and Aleco. Good material is the base of long lifespan. Usually it last 15,000-20,000km.
Stone chainring’s tooth is unique design of Stone. Now it evolution to 8th generation. It different from 99% chainrings on market.
Now all Stone chainring works with MTB 8-12s system.
Works with Road bike 8-12s system(default not work for AXS flattop 12s)
We can customize for AXS flattop tooth for all BCD chainrings(need surcharge)
High Precision CNC Process: reduce chain noise, shake. Increase the contact surface between chain and tooth, to reduce wearing of tooth.
Tooth bottom have slot to contain soil and extrusion soil.
