Drivetrain help please
Guys, need some help. I'm setting up my new drive train (SLX 10sp double) with SLX rear and shifters. Trying to sort the rear mech. Got the lower jockey wheel in line using limit screws but when I connect the cable and try shifting I get a problem. Basically I can shift to the lowest gear but the upper jockey wheel stops the chain moving to the upper cog. Even with the b tension screwed all the way in. So I am wondering if the chain is too long and not putting enough tension on the mech so it is in the correct place. I set the chain length as large ring - large cog + 2 links.
