Hope’s T-rex  Range EXpander Sprocket is a cheap way to give yourself a drive train weight reduction and simplistic gear setup utilising a 1×10 setup.  By using the 40T sprocket on a 1×10 you retain usable ratios, without the cost of a 1×11 setup. You must choose between either the sram vs shimano version. The idea is to remove the 17t sprocket from a compatible cassette.

  • Shimano version compatible with XT M771 and XTR M980 11-36 10spd cassettes
  • SRAM version compatible with PG1030, PG1050 and PG1070 11-36 cassettes

We recommend that you use a website like BIKECALC to make sure you select the correct front chain ring to give you the required ratios.

The weight saving is not to be sniffed at, removing your front shifter, front mech and 2 rings off the bike can easily add up to 500grams.

To get the best out of the T-rex sprocket you will need to remove your front chain ring and replace this with Hope’s Retainer ring.

Hope T-Rex Expander Sprocket

The Hope T-Rex is an innovative idea from Barnoldswick. You will see more people on the trails with a 1x10 setup. It would be nice to see the full range of colours appear soon.

To get 1x11 performance out of cheap 1x10 components. The Hope Trex sprocket is a must have. Less fuss and easy gear setup and reduced weight all at the same time.
