    The Hope T-Rex ratio expander allows you to upgrade your existing 11-36 10spd cassette to give an 11-40T range. The T-Rex simply installs behind your existing cassette and replaces one of the smaller sprockets, usually the 17T.

    Description

    Shimano and Sram specific 40T sprockets have been designed, this gives us the following benefits which wouldn’t be possible with a larger sprocket size or with a universal type design:
    1. Precise matching of the tooth profiles and shifting points specific to each cassette
    2. Perfect mating of supporting tabs reducing flex and aiding shift performance
    3. Lower B-tension adjustment is needed ensuring good shifting throughout the cassette range compared to fitting a 42t

    Installation Notes
    Note 1:
    For a 1 x 10 set-up with a newly converted 11-40 cassette you will need a rear derailleur with a 29T capacity [ 40-11=29 ]. For a 2 x 10 set-up with 40/28 chainrings and a newly converted 11-40 cassette you will need a rear derailleur with a 41T capacity [ (40-11)+(40-28)=41 ].

    Note 2:
    In most cases we recommend removing the 17T sprocket. In the case of the Shimano
    CS-M980 and CS-M771-10 this is the only sprocket that can be easily removed. In the case of the SRAM PG-1030, PG-1050 and PG-1070 it is possible to remove alternative individual sprockets.

    Note 3:
    If your B-tension screw is not long enough use the supplied M4 x 20mm screw. Refer to the manufacturer’s instructions for further guidelines on adjusting your rear derailleur.

    Note 4:

    With the chain mounted on your largest front chainring and the 40T-REx sprocket, check that your chain is not being pulled tight. If your chain is not long enough, replace it with a new longer one
