I would like to attain more "holding power" from a front bar end shifter. I am using an Ultegra FD-6503 front deraileur and Bar-End Shifters - SL-BS77. How can I get more holding power in the front bar end shifter? As I ride along, especially over bumps, the spring tension of the Front Deraileur pulls the shifter towards a downshift.
Is there a method to get more holding power?
Is there another bar end shifter that has sufficient holding power to counteract the FD spring under all riding conditions.
I would appreciated a direct response to: dave at ornee dot net

Tighten the screw at the pivot of the shifter. Use a good screwdriver and crank on it- it'll take a lot more torque than you can dish out.

Jeff and Peter are correct. The Shimano tourque specification is 21 - 26 in. lbs. That is what I tried. I then tried tripling the tourque... still not enough holding power. I finally tried 25 foot pounds. I was finally sucessful at this tourque... 12 times the factory specified amount. I would'not have believed it if I hadn't heard it here and tried it. Thank you, David Ornee, Western Springs, IL foot pounds

Geez- a torque-measuring screwdriver... whoda thought? I just cranked on mine until they stopped moving. That's what you get when you're educated at GBH Bike Shop (Getta Bigger Hammer). :-)

I have screwdriver bits and Allen bits that fit my torque wrenches. I have one torque wrench for inch pounds settings up to 250 and another for Foot Pounds. Both wrenches have the preset method to determine when I have reached the specified torque.

It's easy enough to use any regular bits in a regular torque wrench. For screwdriver bits, they're usually 1/4" hex drive, so just use a 1/4" socket on the torque wrench. For allen bits, I have a hard time finding large allen bits with 1/4" hex drive; so it may be necessary to cut the end off of a regular allen wrench, and use it in a socket of the same size (7mm allen wrench? 7mm socket.).
Anybody know where to get 1/4" hex drive allen wrenches in sizes larger than 1/8"?

I got mine from Park Tools; called " Torque Wrench Sockets and Bits Set TWB-1" shown at the Park Tool web site at URL: http://www.parktool.com/tools/TWB_1.shtml I don't know about any 7 mm Allen wrenches. I bought the screw driver bits at my local hardware store. You are correct, Rick, I hold them in a hex socket that mates precisely with them. David Ornee, Western Springs, IL

Yup, every time I go into a Sears, I look...and I go into Sears almost as often as Tim Allen. Okay, more like once every two or three months...but enough. They never have 'em.

Don't know specifically in Providence, but there's one in Warwick and one in North Attleboro, MA, each of which I've looked in. I did find a nice folding tree saw for MTBing, though.
