Ok, tried asking this on some road forums and they were all NFI due to it not being Durace etc Have Shimano 105 5700 setup on CX bike, running 1x10. Dont want to shell out for 1x11 and hydros just yet. Want bigger rear cluster. Wondering if its possible to do the B-screw mod on a 105 mech, like it is on the Shadow mechs to run larger rear clusters on 1x10 on the MTB. Considering this as i have a couple of spare 32T max rear clusters for the MTB, but no smaller NW chainrings spare. Not anywhere near the bike at the moment, so a bit hard to check. Anyone mucked around with this? Edit: Ugh, in wrong sub-forum. Anyone want to move it to Parts n Stuff.
