TRP EVO CR-M9050 Cinch Chainring

TRP's 12-speed chainring for the EVO cranks — CNC-machined 7075-T6 alloy with the Wave tooth profile that holds a chain without a guide.

Highlights

  • Wave tooth profile for chain retention on rough ground
  • CNC 7075-T6 aluminium: light and hard-wearing
  • 30, 32 and 34T
  • Boost (3 mm) or 0 mm offset to suit your chainline
  • Black with gold or grey accents to match the group

TRP quotes 70 g for 30T, 79 g for 32T and 91 g for 34T in the Boost 3 mm version. Choose Boost 3 mm for Boost-spaced frames and the 0 mm offset where a wider chainline is called for.

Fit and compatibility

Cinch direct-mount interface — fits TRP's CK-9050 and CK-8050 cranks and other Cinch-standard cranks. Not for the 6 mm-offset DH crank.

Choose your chainring and colour and offset from the options above. Not sure what fits? Ask us — we fit and service these in our workshop.
