Sram MTB Gx Type 2.1 Long Cage Rear Derailleur - Black, 10-Speed

Sram MTB Gx Type 2.1 Long Cage Rear Derailleur - Black, 10-Speed

Q: What size should I use for a 36 -11 casette?

Forgive me, but you are asking the wrong question.The cage size is controlled by the maximum amount of slack chain created by the combination of chain rings AND cassette. This is called "Chain Wrap".To formula for chain wrap is (Big Chain Ring - Small Chain Ring) + (Big cassette Cog - Small Cassette Cog). So if you are using a compact double chain ring (50-34) and a 11-36 cassette the numbers work out to (50 minus 34) + (36 minus 11) or 16 + 25 = 41. This means that if you shift from a big-big combination to a small-small combination, your derailleur has to be able to handle 41 teeth of loose chain, which calls for a long cage. On my bike a have a single 40 tooth chain ring and a 11-42 cassette so the chain wrap works out to (40 - 40) + (42 - 11) = 0 + 31 = 31. So even though I have a huge cassette I only need a medium cage because I have no front derailleur to create more chain wrap.Hope that helps.

Q: what is short, medium.long cage?

It has to do with chain wrap capacity. Small=30t Chainwrap Capacity, Medium=35t, Long=47t. The wrap is just the difference between the number of chain ring teeth plus the difference between the cog teeth. For example a 53/39 with a 12-25 cassette requires 14 + 13 = 27 teeth of wrap capacity needed from the RD.

Q: Will this work with Shimano Ultegra shifter

No, actuation will only work with sram.... The good news is that it will work with both sram 10 speed road and Mtb... Unlike the newer 11 speeds witch are road or mtb specific.

Q: Can this be used with a shimano 11/42 cassette ?

I used it with a sunrace 11-42 cassette but I needed a longer b tension screw(which was not provided) so you will likely run into the same issue.
