Shimano Ultegra right shifter(8 posts)

While out on a ride today the bike was not shifting correctly. If I did a multi shift to a lower gear (big twist to the left, the shifter would freeze up until I fiddled with it and returned it to it's normal position. I thought it needed a little lube and I would be good to go as I have had this happen before and that was the fix. It happened again within a mile of lubing the shifter and I took a closer look at the problem. A small screw on the underside of the levers that is sheilded by the hood body but exposed on mutiple cog shifts was hanging up on the edge of the hood body. I tightened it down as best I could with a bladed SD (the screw is philips) and continued the ride. It was loose again by the time I got home. Anyway to prevent or fix this or has anyone else had this problem. Maybe teflon tape?

I had the same problem. My shifting was getting real loose and sloppy and when I was cleaning my bike I discovered that the little screw had fallen out. I replaced it and tightened it down real good and was planning on using locktite but it hasn't come loose again. Loctite would do the trick....

Did not have the Loctite on hand so I used the teflon tape. Similar to what airplane mechanics do with bolts to keep them from rattling loose is use silk thread around the bolt shaft.

Mine are the 6500 that were notorious for having the buzzing brake lever dust cap..... also the only screw I could locate in my garage was a little larger than the one I was replacing. I think that might have made a difference....

Came on a '99 bike so I would guess the older 6500 model. You got to do a full twist downshift and hold it there to see the screw exposed.
the screw in question is abear
