So i built a new bike last week. I installed a Shimano XT rear derailuer. Discovered there was no barrel adjuster. Realized that they were on the XT shifters. Did not buy XT shifters because i'm using these instead:
I was going to use those Jagwire "Mickey" adjusters that slip into the cable housing stop but they weren't going to arrive in time. The LBS had afew barrel adjusters that they let me have for free.
