Guys, I thought I knew how to set my front derailleur, but I seem to be running into a snag:

I am adjusting my h-limit screw on my front derailleur, and I seem to be at the end of the adjustment, but the chain is still rubbing on the outer plate of the derailleur cage. How do I fix this? :madman: :madman: :madman:

I am in process right now but will keep checking for answers as I work.

Are you by any chance riding a steel frame with a clamp on derailleur? Because the smaller diameter tubing means the derailleur is closer to the centerline than it might be with a fatter tube. Combined with cranks sitting farther out, such as with the outboard BBs or because of an overlong spindle, you've simply run out of travel.

Fixes-- Try to bring the cranks inboard a bit, if possible, or consider a larger diameter clamp-on derailleur and shim stock to bring the derailleur out. If it's a braze-on FD and you only need a bit more reach, some skillful filing of the boss or the derailleur body will allow you to move it outboard a millimeter or two.

BTW- not all derailleurs are created equal, so possible another brand or model will have a bit more reach outwards.

If all else fails, stop banging you head on the wall, try convince yourself that you really wanted a double setup with a bashguard in the first place.

I'm having the same issue too...bought a new external bb crankset and trying to use my old 34.9 clamp shimano lx front derailleur (worked fine with the isis bb). have the low limit in and the high out as much as possible...looks like the chain in the lowest gear would be on the external bb. grrrrr. guess i'm buying a new derailleur too.
