[RBW] Re: Problem with adjusting the rear derailler / bar-end shifters
It seems like the shifter is working now! :) Almost too embarrassing to tell how it went. I never got the shifting adjusted while the bike was in the stand (actually 2 different stands). Trust me, I tried everything. That’s why I never tried it loaded - the shifting seemed far too nasty for that. Then I went for a ride today and headed to the hills nearby. I was riding with friction shifting, but thought I’d try the indexing just for fun for those gears that worked. I actually read the link that Eddie mailed (Thanks Eddie!). The article said “Most bikes shift differently in the stand than they do under load.” So I gave it a try. To my great surprise, the shifting was completely different under load. So I actually got the shifting adjusted so that it works fine on all gears. It was much easier than while the bike was in the stand. I couldn’t hear any noise or anything from the gears. But it was very windy and hard to hear anything, so we’ll see. All the gears seemed to be allright though. It’s still a mystery to me why it didn’t work in the stand, but I guess it’s two completely different things to use it under load or unloaded. Thanks for all the help! If you have any reflections around this, please let me know. Regards, Juhani -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

Hi guys, Yes, I’m still trying to figure out the problem. I promise I'll let you know if I get it fixed. At the moment, I’m riding the bike with friction shifting, but I hope the indexing is eventually going to start working. I'll show the bike to the mechanic in my LBS next week. The guy in internet shop who sold me the shifter (and the other stuff) is going to talk with his mechanic as well. Maybe they can figure it out. Thanks for the link Eddie. I’ll check it out. And thanks for the advices Jim. I’ve checked all the housing ferrules and I think they’re just fine. Also both cassette and freehub body is correctly torqued.

The cable is routed correctly I think. Here’s a link to Shimano’s technical instructions for the derailleur: http://techdocs.shimano.com/media/techdocs/content/cycle/SI/SI_5W50A_001/SI_5W50A_001_En_v1_m56577569830616237.pdf I’ve followed the instructions and secured the cable in the groove as supposed. What a mysterious problem... J -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

[RBW] Re: Problem with adjusting the rear derailler / bar-end shifters
I called my LBS, but they’re leaving to a bicycle show over the weekend. Their mechanic ask me every same question as you guys, and he couldn’t understand what could be wrong. He told me that it sounds like it’s something wrong with the shifter or that Shimano has changed the cable pull for the 2010 rapid rise XT (which he hadn’t heard of). He said that even with quite bend derailleur hanger the index should work quite OK. So if it looks as straight as mine and works fine with friction, he thought it couldn’t be the problem. What do you think? I live in a country side and this is the only good bike shop here. Sometime after the weekend I could go and show him the bike if I haven’t figured it out yet, but he said he really hasn’t clue what could be wrong. I triple checked that the shifter washers are mounted correctly and added torque to Shimano’s recommended max 3Nm. But the problem remains. Friction shifting works fine though.

[RBW] Re: Problem with adjusting the rear derailler / bar-end shifters
Thanks for all the answers. Earl Grey: Yes, the shifters is 9-speed (or atleast it has “compatible with 9-speed” text on it). I used Silver Shifters before, but I found it really difficult to shift between the 4 largest cogs on 11-34 9- speed cassette while riding uphill with some cable tension. That’s why I wanted to go indexed. reynoldslugs: Did changing to Paul Thumbies solve the problem completely? Is the shifting as fine as with your Bob Jackson now? Jim: I checked that the cable is routed and attached to the derailleur correctly. The derailleur hanger looks just fine, but I don’t know how to check it more than that. Kuma: If I adjust the cable so that the 3-4 largest cogs shift nicely, the 3 smallest ones won’t - the derailleur jumps over the 2nd smallest cog and the smallest and 3rd smallest make noise. If I adjust the derailleur so that the 3 smallest cogs shift nicely, the largest ones won’t - the derailleur jumps over the 2nd largest cog on the way down and on the largest cog the chain rides on the top of the cog almost dropping down to the smaller cog. 3rd largest makes noise as well or the chain rides on the top of it. Frederick, Steve: The dropouts are vertical. AJ: The washer is installed correctly I think (pointing straight down). Would it shift all the 9 clicks, if it was installed wrong? I also loosened the cable and tightened it without the 4th hand tool, played with different cable tensions and positions with the adjuster. Nothing really helped. So basicly the problem is that on the largest cogs I’d need more slack on the cable and on the smallest cogs I’d need more tension on the cable. Any more ideas?

[RBW] Re: Problem with adjusting the rear derailler / bar-end shifters
Yes, it’s frustrating because I’ve only heard good things about this combination, but for some reason I can’t get it right. My rear cassette has 9 cogs for sure. And even if it didn’t, my Dura Ace shifters has written on them: “Compatible with RD-7700(9s) RD-7400(8s)”. So it should work even with 8-speed cassette, right? I haven’t taken the rear derailleur apart so the pulleys are in the same place as it was mounted in the factory. It worked fine with the Silver Shifters - except my problem with dialing in the biggest cogs right. And now I can get some of the cogs working - like 3 largest or 3 smallest - but not all of them at the same time. I haven’t torqued the mounting screw with a torque tool, so I’m not sure, but I don’t think it’s over the 10Nm recommendation. I could try to loosen it up a bit, if you think it could cause the problem. -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

OK, but anyways it's a Shimano XT 9-speed cassette with XT 9-speed chain. I counted the cogs. -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

[RBW] Re: Problem with adjusting the rear derailler / bar-end shifters
I mixed things a bit in my answer about the torque. The bar-end shifter pods are torqued without tool, but I think they are just right - around 7Nm. They seem very sturdy. The screw that goes through the middle of the shift lever is tightened with a high quality torque tool to recommended 2,5Nm - and the shift lever feels just right with the “clicks”. The rear derailleur attachment bolt is torqued without a tool, but should be around the recommended 10Nm. The derailleur hanger looks just fine - it doesn't seem to be bend in anyway. Should I be able to see if there was something wrong with it? In friction mode the shifting works fine. Or could it mess up the index shifting if it was off just tiny little - not visible for eye? -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

[RBW] Problem with adjusting the rear derailler / bar-end shifters
Hi, I’ve problem with adjusting my rear derailleur. It’s a Shimano XT 9- speed low normal (rapid rise) with XT 11-34 cassette and XT 9-speed chain. All of those are quite new and shouldn’t be worn out. The cable is new and just lubricated and the housing should be fine as well. The shifters are brand new Shimano Dura-Ace 9-speed bar-end shifters which I’m trying to install. Adjustment of the B-screw and H- L-limit screws should be fine. I turned the adjuster on down tube cable stop halfway between all the way tight and all the way loose before attaching the cable. The cable is tightened with 4th hand tool so there shouldn’t be any slack in it. I adjusted the rear derailleur like this: I chose the middle chain ring in the front and shifted to second largest cog in the rear. Then turned the adjuster until it shifted to third cog. Then I turned the adjuster back so that the derailleur shifted back to the second cog. And finally adjusted it so that it wouldn’t make any noise. The derailleur shifted relatively fine on the biggest cogs, but not the 3 smallest ones. If I adjusted it so that the smallest ones shifted fine, then the biggest wouldn’t - and vice versa. Any ideas how to get it right? The low normal rear derailleur and Dura-Ace bar-end shifters should be compatible, right?

[RBW] Re: Friction shifting with Dia Compe bar end “Silver Shifters”
Thanks for the answer. I guess I need to go to the closest hills and ride around until I learn how to shift :) Did you mean that for the steeper hills, before it gets steep I should figure out a gear that I can maintain the whole hill? So I actually wouldn't shift at all when riding uphill? 2010/8/17 Jim Cloud cloud...@aol.com: When you're shifting while climbing you really need to anticipate a shift and begin changing gears before the grade of the hill becomes steeper. If you're trying to shift with any substantial pressure on the pedals there's too much tension on the chain to allow the derailleur to move the chain up on the cogs. If you've gotten into the grade and cannot easily shift it's better to dismount and spin the pedals as you lift the rear wheel and move the shifter lever to get into a gear you can maintain on the grade. Keep practicing, it will become second nature to anticipate a gear change in advance of the increasing grade of a hill. Good Luck!
