Pah Bear Posted November 23, 2017 Share Have a 10x XT version and use both the 38/26 and the 38/24 crank sets coupled with a 11-36 cassette with zero issues. Can't see why not. Link to comment Share on other sites More sharing options...
Mr lee Posted November 23, 2017 Share Tell us what you are trying to achieve? You looking for a setup with high top end speed that will climb a vertical wall? The no-level 2x10 I had before going 1x11 was 36-22 so you should not have a problem. I honestly think you will have all you need with a 36-26 with the 11-42! 36 - 11 should easily give you around 50+km/h on a flat...on a 29r 26 - 42 is also plenty for climbing Edited November 23, 2017 by Mr lee Pah Bear and CdT85 2 Link to comment Share on other sites More sharing options...

However its worth a try . Mr lee 1 Link to comment Share on other sites More sharing options...

However its worth a try . Thought there was a reason why but could not figure it out and it makes sense. He might get away with it if he uses an older and longer cage derailleur....if it works great, if not let us know but why mess around? Just use as intended to avoid the frustration Link to comment Share on other sites More sharing options...

Well then you need to stay with 3x10 if it is that big a problem....otherwise you will need to come to a compromise. What bike do you have any what is your weight?

Pah Bear Posted November 23, 2017 Share Well then you need to stay with 3x10 if it is that big a problem....otherwise you will need to come to a compromise. What bike do you have and what is your weight? is the question you have to answer. Being a big guy myself, I preferred the 2x 38/24. Will really have to thin(k) carefully on a 1x set-up.

Knersboy Posted November 23, 2017 Share I run 2x11 with a 24-38. Works fine with a 2x10 front derailleur and 2x10 crank. Reckon you will definitely need to change the FD. A question, can you get your hands on those chai rings individually or must you buy as a pair? Link to comment Share on other sites More sharing options...

Mr lee Posted November 24, 2017 Share As long as you have enough gears for climbing with the selected ratio's you will be fine. Use the down hills for resting so you can give it horns on the next uphill I am 116kg's and don't need to peddle on the down hills as gravity gives me all the speed I need.My top speed on my MTB at the 947 was 70KM/H and that was just free-wheeling from the top of whatever hill! Obviously I needed to bend down and tuck-in as much as possible because my long body creates loads of drag which acts like an air-brake. I even passed a few roadies that were peddling Martman 1 Link to comment Share on other sites More sharing options...
