Hi, sorry if this has been asked before...I did search and could not find any posts on this on the site. So if its discussed elsewhere, please direct me there... Anyway, on to the question: I have been sitting on the fence for long enough to have look at whether this 1x12 thing SRAM started was gonna turn out to be a fad, but then Shimano joined the fray and I think I may be getting to the point where I am convinced there are merits for me to move from 2x11 to 1x12. What would I need to be able to go from 2x11 XT to 1x12 (either SRAM or Shimano)? I have heard that I would need to change to a XD driver body for SRAM (not that I actually really know what that means???) and I assume I would need to do somethin gsimilar for Shimano 1x12. Does changing a driver body mean also a new hub (i.e. a complete wheel rebuild)? I also know that there are aftermarket etsups or conversion kits, but I only want advice on what I need to do to go from Shimano to SHimao or Shimano to SRAM fully OEM and without "'n Boere plan". Thanks in advance...

Can a 2x11 with shimano M7000 11-46 casette and RD M7000 SG (short cage) work? I know the spec indicates 42 max for 2x11, but is somebody maybe using a 46 on a 2 x 11?

I have a confusing question... I'm looking at buying the new XT Di2, but... The new XT Di2 RD is only available as a GS (Medium Cage) and claims to have a max capacity of 35T, which seems normal for a GS RD. However, Shimano markets the XT Di2 as being both 1x11 and 2x11 capable. They say you can use the 11-46 cassette for the 1x11 and either the 11-42 or 11-40 for a 2x11 setup. From Shimano product page for RD-M8050-GS: Series : SHIMANO DEORE XTMaximum Sprocket : "42T(2x11-speed) 46T(1x11-speed)"Minimum Sprocket : 11TFront Difference : 10TTotal Capacity : 35THere's my dilemma. Even if one uses the new shimano 10 tooth difference crank (say 36/26) both the claimed 2x11 setups exceed the maximum capacity of the RD. Using the 11-40 cassette and the 36/26 chainrings (which needs less capacity than with the 42T cassette) this gives us a 10+29 needed total capacity of 39T. The school I went to thought me that 39>35. With a 42T cassette, the needed capacity climbs to 41T. So theoretically the XT Di2 RD won't handle the stated 2x11 setups based on the stated capacity. What am I missing? Do I need to get the SGS XTR Di2 RD for this to work as 2x11? Does this only apply to some programmed SynchroShift which manages the total capacity? So before you ask why not just do 1x11, my other bike is a 1x11, ... I like my short gear spacings for long rides (ex roadie) Any ideas? Anyone from Shimano care to shed some light on this?

Need some help!!! Trolled the net to death, but not able to figure out the differences between the 1x11 and 2x11 SRAM GX rear derailleurs? Yes you get two versions, never expected it: https://www.sram.com/sram/mountain/family/gx http://www.chainreactioncycles.com/za/en/sram-gx-1x11-speed-rear-mech/rp-prod135897 http://www.chainreactioncycles.com/za/en/sram-gx-2x11-speed-rear-mech/rp-prod135898 After looking at the SRAM tech docs, it seems that the 1x11 is only avail in a long cage version that makes sense, but apart from that, what is the real world differences, will a 1x11 unit work on a 2x11 setup. As I see it , it is as easy as the rear derailleur should just be able to shift 11 gears. Shimano only has one 11sp Xt derailleur, why does Sram need 2? Looking at GX 2x11 crank + 104bcd single chain ring, 2x11 front derailleur, XT 11-42 cassette (due to XD driver), xt chain, SRAM GX shifters, but the rear derailleur is the Q? The above will enable me to experiment with a 1x11 setup and still be able to change over to a 2x11 setup for the days that you start at the back and need to work your way thru the walkers on the hills, or help to get to the end of the TransBaviaans.
