Barend FD shifting problem with Triple
 
I'm switching from SRAM X4 8 speed 11 speed. I installed a Shimano XT 8000 11 speed with Microshift Mega 11-Speed MTN Bar End Shifters. They are shifting the XT RD great, but the Microshift FD is not. I was under the impression that the "speeds" of a FD were not that critical. e.g. 8, 9 & 10 speed FDs were interchangeable? The existing 9 speed shifted the original 8 speed fine. It could be that I just suck at setting it up.

At any rate, the FD is the same Microshift 9-speed unit that came with the 48, 38, 28 triple. The FD shifter is friction. Suggestions?

So it sounds like you are having a problem shifting between the three chainwheels on your triple crank. Could you describe what that problem is?

Pretty much shifts like crap in every direction. Goes too far, sits on the chainring badly for a rotation, etc. It worked fine with the 8-speed chain using the same derailleur and chainrings. And having the shifter in friction should give control? However, I have NO barrel adjuster inline at the moment. I'll rectify that tomorrow. Then l'll try again.

What do you think the shifter has to do with that? It sounds like your FD is way off if the chain isn't even staying on the chainring once shifted. Unless your shifter isn't holding its position and slipping, I can't see how the shifter would cause the chain to move around.

For friction you don't need a barrel adjuster. If you (optionally) want to get rid of all cable slack, set the L stop a little too tight, tighten the cable, then back off the L to where it was.

A barrel adjuster serves nearly no purpose with a friction shifting arrangement. As long as the limit screws are set properly and you didn't leave too much slack when you attached the cable to the fd in it's most "relaxed" (smallest chainring) position the shifting should be fine. However that assumes you have the fd's cage close enough to the largest chainring and aligned well.

Thanks. Re-adjusted it is working better--especially while riding as opposed to on the work stand. I guess I'm capable of more finesse while riding.
