[RBW] Re: New build: Soma GR, and a question
I somehow managed to wind up with two left-hand (FD) cable stops, so one of my bikes has the right-side/RD one mounted in the upside-down orientation. It does visible bend the cable line slightly, but I haven't had any issues with shifting or indexing.

I have a Shimano FD built to the same design, and it seems to have identical lever arm lengths for the top- and bottom-pull configurations, so the amount of cable pull required *should* be the same. Can you be more specific about the trouble you're having? I took that one off my Sam Hillborne because it wasn't shifting well, especially into the small chainring - my new road derailleur that looks like the IRD works great, though.

Re: [RBW] Re: New build: Soma GR, and a question
Can't shift into granny, can't shift into big ring. The derailer does not seem to move to the limits that i set with the screws. I took the chain off to double check the limit screws and the settings looked fine.

[RBW] Re: New build: Soma GR, and a question
Measure your chainline. You probably have a roadish chainline, which may explain why your mountain front der can't drop you to the granny. That's problem #1 If you can't pull up to the big ring either, even with the limits all the way out, then that indicates your shifters don't pull enough cable for that front der. That's problem #2 If those are your only two problems, then replacing the front der should solve them both. A road triple front der should work with a roadish chainline. A shorter lever arm where the cable attaches requires less cable pull to make it move.

[RBW] Re: New build: Soma GR, and a question
I think your derailleur should work without issue, but if it's not shifting at all then there must be some issue with the set up. I did notice a couple things... I see your downtube cable guides are mounted backwards/upside down. The little bullet adjusters hang down from the stops. They just need to switch sides. That shouldn't impede the cable though. It also seems like both your limit screws are pretty far out, so I dont think you have it locked into a short range of motion. My first thought is to be sure the cable is not accidentally pinched in the bottom bracket guide. Some have a small plate and screw to hold them on and I've had my cables get crimped in there. Along those same lines, trace the entire cable to be sure it's free. To check, just unbolt the cable from the derailleur and while pulling it taut with one hand, move your shift lever with the other. Also not a bad idea to manually pivot the FD to be sure it's not bound up. The other thing I noticed was how the cable was routed into the pinch bolt. It seems minor, but try running it down through the indent then wrap the cable end under the bolt towards the non drive side. This picture shows the indent pretty well: https://www.flickr.com/photos/23646261@N03/14725333997/in/set-72157646439942592/ Another thing I've done and driven myself crazy with, is not having the front shifter all the way down before I clamp the cable. When I get FD issues, I usually just unbolt the cable and start from scratch. Check my lever, check FD height/position, check inner limit screw, then clamp the cable, slowly shift up to big ring and set outer limit screw, then shift back and forth to be sure all's well. -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

As per the cable stops: The Riv has the barrel adjusters below the mounting bolt, The GR has them above. Yes?

No, they are both above the mounting bolt. Heck, on my Paul Taylor that has head tube mounted cable stops, it would be impossible to put them on below the stops.

Re: [RBW] Re: New build: Soma GR, and a question
But it is designed to be mounted hanging toward the bottom of the downtube. Yup, that's what I meant by above/below, which also could be confusing, because it's relative to a specific point. In reality, I doubt it would be the source of your shifting woes. I have a bike with Suntour Symmetrics shifters (braze-on mount on top of the dt) that would have the same cable angle to bb guides, and it shifts fine.
