My road bike has an internally routed rear brake cable, which got me to thinking, anyone make a cross bike with internally routed cables? Any disadvantage to it that you can see? Besides cost?
That was my thought. Granted I haven't even raced my first race yet. I'm probably overthinking this, but figured what the heck and see if it was do-able and/or practical.PeanutButterBreath said:Not having any cable on the exterior of the TT or DT would be nice.
I had thought about that for the next CX frame I built - brake cable through the top tube, as usual (usual road bike), and both derailleurs through the downtube (which would eliminate a front-derailleur barrel adjuster, unfortunately). The thing that makes me nervous, though, is cutting fairly large holes basically right through the butts. Those brass tubes are generally 7 mm OD, I think, and when you factor in the long oval they require for smooth routing, it seems like two of them opposite each other on the downtube would generate a pretty large stress riser. The other option, three tubes through the toptube, which is at least subjected to different stresses, doesn't seem much better... Dunno, but I'd like to find a nice way to eliminate the usual gaggle of cables on a good CX bike's toptube - besides another singlespeed!PeanutButterBreath said:I may do the same with an old CX frame at some point, just for kicks. Not having any cable on the exterior of the TT or DT would be nice.
Believe it or not, that's my favorite thing about it. This applies more to on-road use, but it's so much nicer to sit on at stoplights, too...PeanutButterBreath said:Also, when you sit on your TT drinking a beer after the race you won't be rubbing the cables into the paint.
Looks nice, but the mech cables are downtube run and exposed. Seems counterproductive to me. Granted I haven't raced cross, but it makes sense to me to top tube route everything to keep it out of the mud, like on mtn bikes.gandhi said:Fixie Inc's cyclocross "Pure Blood" has internal cable routing. http://www.cycles-for-heroes.com/bikes/cyclocross/pure-blood. Very slick indeed.
I wonder though, if mud can find its way into those holes? It also seems tricky to replace the outer cable.
