Sram Red RD -- Won't shift into largest cog
Hi Folks-
I just got finished swapping my Tarmac over to Red (largest endeavour to date), and I have run into a little snag. First off, everything went on nicely, and the directions were clear, so I am pretty happy! However, I am having one tiny problem with the rear derailleur. When I go to downshift into the largest cog, the chain shifts to the cog then immediately clicks out of it. I set up the limit screws as per the instructions, and the RD shifts great through all of the other gears in both chainrings (symptoms occur in large and small chainrings). Any tips? thanks folks! Happy 7/4!

Loosen low limit screw a bit more. If that doesn't work, reset cable tension and start over.

Just adjust enough so that pulleys are lined up nicely with the largest cog, and so that it shifts well. Just don't overdo it or it'll obviously fall into your spokes.
If for some reason you've already loosened the low limit screw so much that it doesn't seem to be making a difference, then just try resetting the cable tension (don't forget to re-tighten that low limit screw). Use a cable puller if you have one.

Add tension to the cable. This is usually 1/2 turn or so counter-clockwise on the barrel adjuster. Set the low limit screw according to the instructions at https://www.parktool.com. If you back that screw out too much the chain will go into the spokes and probably damage the wheel.
