I wanted to make a suggestion for anyone running rim brakes and using a harness.
http://www.yokozunausa.com/recasy1.htmlI run my cables very short and chose these over nokon cables after doing a lot of research online. They weren't as expensive as nokon systems but they weren't too cheap either. So far I am really happy with their performance. They do not move one bit when braking. If I smush them down it does not affect braking either.
I got them specifically for running a harness [i don't have one yet] and I am hopeful they will not be affected. So far all of my testing is with a dry bag strapped tight to the handlebar.
Just wanted to throw this out to anyone having issues.
