STONE 110BCD 4-Arm Wide Spider – Shimano 12-Speed Fitment and Specifications
This STONE 110BCD 4-arm widen-style spider is built for Shimano 12-speed double chainrings and STONE 110R2B chainrings. Offered in black or silver, it fits road cranksets with SRAM 3-bolt, SRAM 8-bolt, EASTON EC90, and ROTOR Aldhu interfaces — including cranks matched to Shimano R7100, R8100, and R9200 groupsets, as well as SRAM AXS FORCE, RIVAL, and XPLR 12-speed/13-speed setups.
Product Overview
- The widen-style spider is designed around the Shimano 12-speed chainring curve and the STONE 12-speed double chainring 110R2B curve, so the chainring sits perfectly true once installed.
- Works with chainrings for R7100, R8100, R9200, other Shimano 12-speed chainrings, and STONE 110R2B chainrings.
- Accepts two chainrings and supports both 1x and 2x drivetrains.
