Product Details

With the popularity of 1 x 10 drivetrains having really taking off and the search for the perfect ratio seems to be a never ending search of Hope and despair, Hope have released this 40 tooth range expander as a way of getting the ratio of an 11 speed groupset on your beloved 10 speed set up at an affordable price! The Hope T-Rex sits neatly and perfectly behind your cassette an allows you to have a nice super spinny gear for those long mega steep climbs. Hope have designed two types of T-Rex, one to work with Shimano and one to work with Sram cassettes.

The T-Rex will only work if you are using a 10 speed cassette on which you can remove the 17 tooth cog.

Compatible Cassettes

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