Sram RD low/inner limit adjustment
Just installed a Sram Red drive train - shifters, crank, derailleurs, cassette, chain.
Got everything working well. Rear shifting is great - crisp and quick up and down the cassette. I think that cable tension is spot on. Front shifting is working fine.
I encountered what I have come to understand is a common problem with the rear shifting. I set the low limit screw according to Sram instructions. When on the innermost/largest sprocket, if I forget I'm there and attempt to shift again, the shifter clicks once and the chain drops to the higher gear (next smaller sprocket). Because of the limit screw, I can't force the shift past that first "upshift" click.
So I read somewhere that the solution to this is to ease off the low limit screw a little bit at a time allowing the derailleur to move slightly further inward. I did this in 1/8 inch stages until.....
Now when I'm in that large sprocket situation, I can shift "past" that first click, the shifter makes a very loud and rough second click and, for lack of a better term, "releases" rather than moving the cable, and the chain stays on the largest sprocket. But this actually takes quite a bit of force on the shifter. If I apply what I would consider normal force to down shift - in other words, if I just apply the normal amount of force I'd use to shift to a lower gear (which isn't there of course), the shifter will just do that first click, won't move past that, and the chain will move to the higher gear. If I really force it, that second, loud click will happen causing the cable to release and the chain to stay put.
Hope this makes sense. Does it sound right to you? Do I need to ease it off a bit more so less force is needed? I DO NOT want to shift into the spokes!!
I don't know if this is actually the proper way to set this up - I'm a little disappointed that Sram doesn't address this issue clearly and understandably.
