[RBW] Re: Atlantis FD Chain Problem - Sudden
First, I owe Jim / Cyclofiend an apology and a little defense of Wally's LBS. Walter is a great guy and never used "Frankenstein" in referencing the Riv setup, that came from my creative mind imagining what he might be thinking going over the unusal setup and was a poor choice of word on my part . He was as perplexed as most here in thinking what might be causing the issue. He made minor adjustments to the FD / limit screws and thought there might be something going on with the BB but suggested I ride it and see how it works. It worked ok today and I'll leave things alone for a while though I will have a new BB on hand just in case. I believe his thought is to work from the inside out. I plan on keeping a copy of Jim's methodical problem solving approach for reference Doug, when gathering the build parts I did check with Riv regarding BB spindle since there was a little controversy on this website re: 107 / 110 / 113. Mine is frame 280 and no they don't keep detailed records regarding sale dates but from the Riv Readers I've pinned this frame to the 3rd or 4th shipment. Grant the man himself spoke from the golden clouds when queried 107 or 110 and specified 107. My guess is that it wouldn't make that much difference with 110 except to give a little more room between the chain stays. As noted the parts are pretty much stock Riv and chain is a 9spd SRAM. I think I'll ping Riv and see what they say about installing the chain with that 12-36t cassette since they sell that setup. Maybe the standard chain sizing technique doesn't apply when you go outside the manufacturers stated cassette range. I think what was the shocker for me is that everything was working so beautifully and then bang it didn't. Thanks all.

Worth consideration, anyway. 9 speed chains are in fact narrower than 8 which in turn was narrower than the old 7 (although 8 is the new 7 as far as chains go) which in turn was narrower than the old 5/6, but in fact 9 speed chains work perfectly well on 8-speed rings and cranks (I have several bikes set up that way) and definitely work just fine on the Sugino XD-2 crank. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Mitch: One additional thought: is the chain 6/7/8 speed width or 9 speed? I've never had one in my hands but I'm told 9 speed chains are narrower than the old standard. My thought is perhaps if 9 speed it's not working correctly with the chainrings if they're standard thickness for wider chain.

[RBW] Re: Atlantis FD Chain Problem - Sudden
Mitch: You've got a tough one. That's the standard crank Riv uses on tons of bikes, & came on my Atlantis with 24/36/46 rings that went around 20k miles. The granny is still original but I've used 34 & 44 rings (something laying around); 36 & 48, and lately 36 & 46. On crankset discussions here, others have posted a wide variety of successful ring combos. I'm struggling to think it's the crank. The BB may be possible. My Atlantis came with a Tange 115 & it always looked like the cranks were too far out but everything worked right so I didn't mess with it. When it finally died (6 years) I worked out the optimal length to be 110 & replaced it with a Shimano 110. It's just close enough to the chainstay that I'll go up to a 113 next time but again everything works so it's not a priority. Others have mentioned using a 115 on the Atlantis just to give lots of clearance for whatever mischief an owner may get into with changing rings, cranksets, etc. With the 110 on my Atlantis, there's so little clearance (+/- 1 mm) between the crank and the stay, I don't think a 107 would work. Mine is an 03. Don't know if there have been any changes that would affect spindle length. Why don't you check with Riv (the serial number is on the bottom of the BB shell; "AT00xxx") & see what BB they recommend? dougP On May 7, 8:57 am, Mitch Browne wrote: > Thanks Jim / all for the considered replies. > > I have visitors this weekend and can't spend a lot of time in the > garage so took the bike to Wally's Bicycle Works, the preferred LBS. > > A little disheartening in that anyone not familiar with a standard Riv > build has to work through the unfamiliar "Frankenstein" setup. > > Wally thinks the root of the problem may the BB or crank.

I'd definitely try shortening the chain before changing cranks. Just to confirm, when you are saying "chain suck", the chainrings are not letting go of the chain where they normally separate at around th 6 o'clock position. Instead, the teeth are holding the chain and bring it up where it's wedging between chainstay and chainring from below.

[RBW] Re: Atlantis FD Chain Problem - Sudden
Thanks Jim / all for the considered replies. I have visitors this weekend and can't spend a lot of time in the garage so took the bike to Wally's Bicycle Works, the preferred LBS. A little disheartening in that anyone not familiar with a standard Riv build has to work through the unfamiliar "Frankenstein" setup. Wally thinks the root of the problem may the BB or crank. BB is a Tange 68x107 not new but looked ok.He will replace that next week. He thinks the crank may have a little wobble from manufacture which could be but I wouldn't know the difference. Chainring bolts are tight and minor adjustments were made to limit screws and this morning the chain didn't fall off on the way in but I was very cautious though I rarely shift roughly. Sugino XD2 is brand new with less than 100 miles on it as are most of the components. I took my time assembling and torqued everything to spec. Greased crank arm bolts but not spindle. The main concern is on going chain suck. This frame may be prone to that since when purchased used (2001 / 2002 model) it had bad chain rash. That was repainted but I hemp twined it for the heck of it and it saved the chain stay from bare metal damage this time around. I am willing to replace the crank if that's what it takes. I googled "Atlantis chain suck" and found some folks had similar problems with this crank that were cured with a different setup. Any thoughts to what might be an upgrade BB / Crankset that would work with this bike? Thanks again. Bummed but riding. Mitch.

[RBW] Re: Atlantis FD Chain Problem - Sudden
I seriously doubt that the derailer is damaged. If you managed to dump the chain on both sides of the crankset on one ride, I also suspect setup issues. Double check your chain length first, then look at the setup of your front derailer. The front mech is a pretty simple device, but the setup gets a little funny sometimes. Check height and angle, then give those limit screws a tweak - preferably with the bike on a workstand so you can check and watch the functioning as you shift it.

[RBW] Re: Atlantis FD Chain Problem - Sudden
I would think that with a new set up re-tensioning the cables would be a first step, and I don't think it could hurt to tighten the set screws a quarter turn and see if it still shifts successfully. The screws could certainly have moved, especially bouncing around on bad, urban roads. I certainly doubt there is anything wrong with the derailleur. I have two of them and have found them pretty rugged. Michael On May 5, 11:35 am, Mitch Browne wrote: > Need advice.

[RBW] Re: Atlantis FD Chain Problem - Sudden
Mitch: You probably haven't damaged the FD; they're pretty rugged. Check your limit screws and take a look at Sheldon's info on chain length & set-up. With a long cage RD, I never found chain length to be critical but it shifts better if it's reasonably close. I've dropped the chain off the granny gear when I mess up the big to middle shift & am out on the smaller cogs, probably not enough chain tension. Over shifting that tosses the chain beyond the big ring is probably a limit screw adjustment. Sometimes with a new build it takes a while for things to settle in. Helps to check stuff for a while after. dougP On May 5, 9:09 am, JoelMatthews wrote: > > Is the chain length right? > > Come to think of it, the symptoms match. > > On May 5, 11:07 am, Bruce wrote: > > > > > > > Is the chain length right? > > > > > From: Mitch Browne > > To: RBW Owners Bunch > > Sent: Wed, May 5, 2010 10:35:42 AM > > Subject: [RBW] Atlantis FD Chain Problem - Sudden > > > Need advice.

[RBW] Re: Atlantis FD Chain Problem - Sudden
Bruce, I have a Shimano HG-61 12-36T cassette which is supposedly beyond the official blessing of Shimano for my long cage XT RD but blessed by Riv. I doubt I'll ever use the 36 but it's on there. I sized the new chain (SRAM 9xx) with the conventional approach and didn't remove any links because it seemed to be the proper length uncut. The odd thing is that it's been shifting fine though the chain is starting to gunk up a bit from daily use. I lube chain with Boeshield once a week and let sit and then wipe off thoroughly. I bought a 3rd eye but never installed it . I may now.
