stoz Posted November 1, 2020 Share Posted November 1, 2020 Dears, I have just acquired the new Cannondale Trail SL2, it is equipped with a 1x12 , Shimano Deore M6100, 10-51, 12-speed 10-12-14-16-18-21-24-28-33-39-45-51 and a Shimano M6100, 30T. A great bike! I'm not a strong rider. It is my first 29er, I'm coming from a Surly Troll 26inch 2x10 speeds. I have tested the Cannondale Trail SL2 during two weeks, I noticed I never used the cogs 10 and 12 . So I have a 1x12 speed system but I really use 10 of the 12 speeds. I'm thinking to move to a 11 speed cassette. Why ? to have more usable cogs! Here is my idea : I will take a Shimano Deore CS-M5100 Cassette 11-speed 11-51 11-13-15-18-21-24-28-33-39-45-51 and remove the 3 first cogs 11-13-15 and replace them by 14-15-16 from a Shimano Ultegra CS-R8000 Cassette 11-speed 14-28 it will give me a 1x11 with 11 usable cogs : 14-15 -16-18-21-24-28-33-39-45-51 (my derailleur will be a RD-M5100-SGS the 1x11) before I had 1x12 with 10 usable cogs : 10-12-14-16-18-21-24-28-33-39-45-51 As you see I will still have the same cogs I used before (on the 1x12) and one new intermediate between 12 and 16, the 15. What do you think about this strategy? Kind regards, stoz (of course I will need to change the rear wheel (for a 11 speed hub), derailleur RD-M5100-SGS 1x11, the shifter and the crank to be 1x11) CS-R8000 https://bike.shimano.com/fr-FR/product/component/ultegra-r8000/CS-R8000.html CS-M5100-11 https://bike.shimano.com/fr-FR/product/component/deore-m5100/CS-M5100-11.html RD-M5100-SGS https://bike.shimano.com/fr-FR/product/component/deore-m5100/RD-M5100-SGS.html Quote Link to comment Share on other sites More sharing options...
