Crossing the right/rear over to the left side makes the cable housing loop around the outside of the head tube, minimizing rub on the paint. It makes for a longer housing but with a wider radius curve. You can usually cross the cable back over pretty easily, either on the downtube for

What is the reason for routing the cables along the bars that way? It seems to me that having them exit the bar-tape at the bottom of the curve would create a nice loop of cable back to the stops, then continuing straight back along the top-tube. I wouldn't want all those sharp bends along the

Yep, I do it the traditional way too; the cables exit the wrap at the front/bottom of the drops, and make a large radius curve to the opposite-side cable stop. I only use the wrap style shown in Steve P's picture when it's needed; for aero brakes and/or brifters. On Thu, Sep 18, 2014 at 9:17 AM,

I've taken the advice to heart of this group and others that the Soma GR I built up recently is really not big enough for me. So I intend on selling it and getting something else that is sized more appropriately for me (6'7). I would like to move the parts form the Soma over to whatever other

You mean, like this? Close. The only difference is that Jim means that the frame will have the two shift cables run along the top tube, like some cyclocross bikes run them. The answer to Jim is YES you absolutely can run your hypothetical new frameset like that. Whether you run barcons

Well in this case the housing runs all the way to the rear derailer. Bill mentioned the additional friction of a longer housing run. But I use Jagwire Teflon with stainless cables and never had a problem before. On Wed, Sep 17, 2014 at 5:08 PM, Steve Palincsar palin...@his.com wrote: On

I have ben experimenting with running shift cables on my top tube. Seems to me the right / rear shifter should go on the right side of the top tube so it runs onto the right seat stay and down to the rd cleanly. Why do you chose to take the right shifter cable to the left side of the top tube?
