I'm using what looks to be the Jagwire adjusters after removing my inline levers.
The rear is fine (plenty of cable there to fit it into) but the front is a bit weird now. Next time I recable, I'm going to try and fit them right where the cables come out from under the tape to avoid the kinking problem I've got with the front. I saw someone else's bike with them there, and it seemed to be a better spot than 2" or so out, where mine are.
For the moment I've solved it by running the housing over the stem to a deep drop cable hanger. Dura-Ace/Textro Oryx combo here.
