    11-speed cassettes >11-32

    We have Campagnolo Athena Triple 11-speed shifting on our tandem. FD, RD, levers. The RD is great, it has a long RD cage.




    I changed the freehub from Campagnolo to Shimano, and so before we were limited to 12-29 cassettes, we were able to change to Shimano's 11-32, along with changing the front chainrings from a 28t to a better-shifting 30t granny.

    We'd like to get a bit more advanage than the 11-32 cassette.

    What's available that's good thats greater than 11-32t? I'm thinking 11-34 or 11-36. We'd like to be able to climb Hicks-Mt. Umunhum.

    Interlock makes cassettes in many different sizes. Anyone else?

    Sram makes an 11 speed 11-36 and also Santana had a batch of 11-36 cassettes made in 11 speed to Shimano specs. We are running the Santana cassette with great results on our K-edge modified Di2 Ultegra derailleur. You have to be aware that just because it has a long cage does;t mean it can handle a 36 it is also dependent upon the placement of the upper guide pulley. On the K-edge cage it is down lower and back further . It appears that we can run the new 11-40 XTR cassette with our set up also just need to use a longer chain and use the high tension hole in the derailleur spring. I will be trying that out this week.
