More Information

The STONE chainring series is made for riders who want a balance of performance, durability and value. Each ring is precision CNC-machined from high-strength 7075 aluminium alloy, giving reliable shifting, excellent chain retention and long-lasting wear for road and gravel riding.

Carefully optimised tooth geometry delivers fast, precise shifting and secure chain hold under demanding conditions, whether you are climbing, sprinting or riding rough roads. It is a cost-effective way to refresh a worn drivetrain, change your gearing or build a lighter bike.

Compatibility

Designed for Shimano 110 BCD, 4-arm cranksets: 105 R7100, Ultegra R8100 and Dura-Ace R9200 (12-speed). Stone also lists the 11-speed R7000 / R8000 / R9100 cranksets as compatible – please WhatsApp us your crankset model to confirm before ordering.

Works with 9- to 12-speed Shimano road chains, and fits 110 x 4 spider-type power meters such as Sigeyi, XCADEY and Magene P505. Not compatible with SRAM AXS 12-speed cranksets (see our Stone 2x Chainring for SRAM), 5-bolt cranksets or non-110 BCD cranksets.
