Overview
Chainring Shimano Deore XT SM-CRM85 28T 1x12
Shimano Deore XT SM-CRM85 is a high-quality 28-tooth chainring designed for Shimano Deore XT M8100 series 1x12-speed mountain bike cranksets. Combining a durable construction with a specially developed tooth profile, it delivers smooth power transmission, excellent chain retention and reliable performance on technical and uneven trails.
The chainring features Shimano DYNAMIC CHAIN ENGAGEMENT+ technology, with a precision-engineered tooth profile that improves chain engagement along the upper section of the chainring and reduces the risk of dropped chains. At the same time, the profile allows the chain to disengage smoothly at the bottom, helping minimise drivetrain noise and friction. This provides quieter, more efficient and consistent pedalling over roots, rocks and other challenging terrain.
The Direct Mount attachment system allows the chainring to be installed securely and replaced quickly when needed. This design contributes to a lightweight, rigid construction while making it easier to change chainring sizes according to riding conditions and gearing preferences. With 28 teeth, this chainring is particularly well suited to steep climbs and technical terrain where lower gearing and precise pedalling control are essential.
Shimano Deore XT SM-CRM85 is designed for use with the Shimano CN-M8100 12-speed chain and is compatible with Shimano XT FC-M8100-1, FC-M8120-1 and FC-M8130-1 cranksets. True to the Deore XT heritage, it combines precise performance, durability and reliability for demanding mountain biking.
