My bike is setup for cable routing under the downtube. I would like to route my rear brake, front derailleur, and rear derailleur cables along the top tube of a bike I plan to use for cyclocross to prevent the exposed cables from getting gunked up frequently with mud or snagged on things when I'm riding through brush in the woods (really bad in the spring / early summer). Reduced maintinance is my goal, I'm willing to take the weight penalty for that since I'm ultimately not ever standing on a podium.
I'd prefer not to use complete housing over the whole top tube, but I'll accept that I'll need to do that and use 6 cable clips (3 in front, and 3 in rear) if there are no better options.
So, I figure I need two things.
1) Something to keep cables on the top tube.
2) A clamp on cable stop to help terminate the brake cable on the seat tube for the front shifter (I've got a mountain derailleur which goes top or bottom pull)
I've seen a 2 cable clamp on solution for 2 cables, the problem solvers backstop, but that doesn't work for 3 cables. What are my options here?
