The QB is shipped with a JIS crank/bb, 103mm spindle. It's really unlikely that RBW mis-installed the crank. How long has it been creaking? Did the bike shop install a new bb not knowing what kind to use? Faced with creaking, I would remove the crank and bb and re-install. Clean the threads, grease them, and re-install the bb. Put grease/beeswax/lanolin on the spindle, install the arms, and tighten the crank bolts to the proper torque. Go for a ride and then tighten the crank bolts again. Some will say to dry install the crank arms. Shelon and Jobst Brandt say grease: http://sheldonbrown.com/brandt/installing-cranks.html If your lbs didn't know what kind of bb, I'd guess they are accustomed to external bb's/BB30, and perhaps there is a more retro friendly bike shop you can find. jim m wc ca On Thursday, September 11, 2014 9:04:33 AM UTC-7, Tex69 wrote: My LBS is having a problem dealing with a nasty creak in the BB area of my (silver) QB.

[RBW] Re: QB BB spec
What brand is the BB? Does the creak happen when both pedals are on the down stroke? Have they ruled out a pedal? I'm sure they removed the BB and regreased the threads before reinstalling. Is there play when the crank arm is pulled side to side? A light coating of oil on the spindle before installing the crank might help. Those creaks can be annoying! Good luck with that!

[RBW] Re: QB BB spec
Same shop some years ago said that original BB installed without grease. I had taken it in for creaking at the time. Pretty sure they replaced original with new one which was ISO as I understand. Oops. Now say that with new JIS still creaks.

[RBW] Re: QB BB spec
also check chain ring bolt for tightness. does the creak happen in and out of the saddle? (eliminates seatpost as source). i'd agree with jim that in most cases the bb and crank are not the real source of the creaking. and also be ok with the possibility that you may never fix it, my solution is to drown it out with a white industries freewheel On Thursday, September 11, 2014 1:18:52 PM UTC-4, Tex69 wrote: Same shop some years ago said that original BB installed without grease.

[RBW] Re: QB BB spec
I like the White Industry idea. As to creaking, it's mostly out of the saddle with gusto, so no weight on the seat of any kind. Some further research says that they mounted an ISO BB a while ago instead of the JIS. Could the wrong BB have bored out the crankarm? -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

[RBW] Re: QB BB spec
Worse when putting a lot of torque on the pedals puts the entire front drivetrain in play as possible cause. Definitely swap pedals with a set you know doesn't creek and see if that helps. That turned out to be the source of my creaking pedals on my QB. With abandon, Patrick On Thursday, September 11, 2014 12:40:11 PM UTC-6, Tex69 wrote: I like the White Industry idea.

[RBW] Re: QB BB spec
Yes, what Deacon said. It's frustrating, but changing one thing at a time is probably the way to do things. The rear wheel is definitely in play, even if you are certain the sound is coming from between your feet.

[RBW] Re: QB BB spec
That's pretty weird all the way around. When I ran non-ferrous frames, one of which had a consistent BB creak issue, we found that using Anti-Seize worked best. Alternatively, plumbers teflon tape can work. I used steel bolts which also helped. I just replaced the BB on my QB with an IRD. The old one had been in there long enough that the removal was especially difficult. The new BB had trouble threading in so I had the LBS-with-the-oldest-mechanics retap the threads. https://www.flickr.com/photos/cyclofiend/14635633463/ That actually helped quite a bit. As others have noted, sometimes a BB creak is any number of other things. I was getting a little noise out of the Suzue rear hub towards the time I retired it. And most of friends with noisey bottom brackets had ungreased pedals or seat posts. RE: JIS and ISO... AASHTA - http://sheldonbrown.com/bbtaper.html One thing you should do is mount the cranks, torque them down (without lubing the spindle) and take off the bolts. Take a look at the amount of room between the spindle and the face of the crankarm. If the spindle was all the way out to the end of the opening in the cranks, then, yes, they did damage. Otherwise, not so much. Unless the cranks are coming loose when you ride or clearly off center when you spin them, I'd tend to think you didn't damage them. Best of luck - creaks can be really crazy-making. I usually take that opportunity to pull everything off (stem/bars/pedals/saddle/seatpost) and regrease everything. - Jim / cyclofiend.com -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

[RBW] Re: QB BB spec
I recently had a creak from the BB area of my self-built Quickbeam. I checked the crank arm bolts, then the chainring bolts. Finally I tigthened the pedals and heard the familiar creak. My beautiful one-owner 1986 Dura Ace right crankarm was cracked at the pedal threads... sniff. -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

[RBW] Re: QB BB spec
Thanks to all. Some good food for thought. Cranks spin nicely and don't make much noise in the saddle, so I guess I'll take my time. One person here said QBs originally came with 103s.

Think mine came with a 107 cartridge in it. Changed it out for a PW so I could fine tune the chain line. That was the shortest one RBW stocks, 108?
