Hey William, thanks so much for pointing out that a shorter bolt holding the shifter to the braze-on might take care of the slippage. I hadn't ridden my randonneuring bike since finishing the Cascade back in June. Yesterday before heading out to Larch Mtn I filed the bolt down put it back on my

I can't advise about the slipping FD except to conjecture that something is keeping the bolt from tightening as it should. But as to the rear, I expect that it is a matter of learning shifting finesse. I have only 7 on the rear, but they are separated by 9 sp spacers (because that is what I had)

I installed the Silvers on my Velo Orange rando bike and have been very unhappy with their performance. There are two basic problems. First, I experienced phantom shifting of the FD. The shifter cannot hold the FD in place in the middle ring (on a Sugino triple). Instead, after a short time, it

I've got a new to me bike coming out of the shop this week with new...yes you guessed it...down tube silvers. I had some Silver bar- enders ready to go but changed my mind at the last minute. The bar- end shifters on my Bleriot have been flawless for 5 years. Hopefully the down-tubers do the tri

You guys are all correct with your observations 1. Silvers don't slip in Barend configuration. Correct. This has two reasons. A. The receptacle (boss) into which the D-ring threads is way deeper, so it's impossible to bottom out. B. More cable and housing means more flex (stretch) can so

I've been much happier with DA downtube shifters than Silvers. But with barcons the Silvers are great. Ryan On Jul 2, 8:24 am, Mike wrote: > So I've been using Silver shifters for a few years now and overall like > them a lot with one exception. When I mount them on the DT on my 63cm > Hilsen o

Thanks for the suggestions William. Just for fun I ran down to the garage and filed a "smidge" off the bolt that holds the shift lever to the DT boss and was able to get the lever significantly tighter. I did a few laps up and down the hill in front of my house and no FD slippage. Funny coinci

Hey William, I appreciate the response. There's clearly good information here. The one thing is, this isn't generally an issue when using BE shifters and has never been a problem with Shimano BE shifters. Later this week I'll have my Surly CC back on the road and that has Shimano BE shifters on it.

Mike This is a very common issue with several very simple fixes. I apologize in advance for a long post As you know, there's a spring in the front derailer that wants to pull the chain down to the small ring. The only thing stopping that from happening is the friction in the shiftlever. If

I have the same issue... Silver DT shifters that slip the FD when I power up. My M.O. has been to adjust it when it slips/rubs. Most of my riding is relatively short distance/time around town so it's rarely an issue. I can imagine how it could become a nuisance on a longer ride. I've tried a va

For what it's worth, I use bar-end Silver Shifters and get the front-derailleur-rubbing-issue when out of the saddle climbing on my Atlantis. I can look down and watch the frame flex as I do this if it's a very steep hill. Sometimes I'll remember to pre-adjust the shifter lever before I begin a cli

I'm 6' 1" & 200 lbs, but I usually only stand up to crest short rollers w/out downshifting. I sit on longer climbs. I have silver DT and BE with 9 speed cassettes. I don't get any slipping in the front, except every once in a great, great while, when the D ring has worked loose. I do get s
