Key Features

  • Adapts a 11-36 10spd cassette to give an 11-40t range
  • T-REx ring installs behind existing cassette, replacing one of the smaller sprockets, usually 17t

  • Compatible with:
  • Shimano XT and XTR 11-36 10spd cassettes
  • Sram PG1030, PG1050 and PG1070 11-36 cassettes

"Giving your cassette big teeth for half the cost"

Shimano and Sram specific 40t sprockets have been designed allowing benefits that wouldn't be possible with a larger sprocket size or with a universal type design:

  • Precise matching of the tooth profiles and shifting points specific to each cassette;
  • Perfect mating of supporting tabs reducing flex and aiding shift performance;
  • Lower B-tension adjustment is needed ensuring good shifting throughout the cassette range compared to fitting a 42t
  • Compatible with: Shimano XT and XTR 11-36 10spd cassettes and Sram PG1030, PG1050 and PG1070 11-36 cassettes
  • Hard anodized 7075T6 aluminium
