Dropout blues - rear wheel pulling out
Gday,
I have an older italian steel frame which I just got second hand and manage to keep pulling the rear wheel out of the dropouts. The dropouts are almost parallel to the chain line which probably doesn't help. Anyway, I read thru previous posts and the comments seem to be distilled to 1. ensure the axle isn't protruding thru the dropouts preventing QR binding properly 2. use a steel nutted QR such as shimano as they bind better than the non steel alloy ones. 3. insert a binding washer ( a serrated washer ) between frame and dropouts 4. score the dropouts as a means of last resort 5. use track axle/nuts I have some questions regarding these and a couple of other things. 1. I have mavic cosmic elite hubs/wheelset. My LBS reckons they're "good wheels which are designed to handle the QR being jacked up as tight as you can get it". I read elsewhere that overtightening QR's can cause compression of the bearings and other equally painful sounding ailments. Any solution will require me jacking the QR up very tight so the q is will I be damaging my hub in the process? 2. do track axles/nuts actually hold the wheel in place any better than a quick release? I so, will this put extra pressure on my hub ala question 1? 3. if i wanted to score the dropouts (eek) how should this be done? 4. will inserting the washers change the rear spacing and affect shifting? If so can i adjust for this simply by adjusting the DR limit screws or is it more complex than that? 5. is the wise options just to kiss my ( ideal barring the wheel falling off thing) frame goodbye, and look for a different less life threatening one? Appreciate any thoughts you might have. Happy flaming, Will

Will: I'm not a big fan of the Mavic QRs; my guess is that you'll find better results if you replace the rear one with a conventional Shimano (or Campy) style. The problem isn't just the mating surfaces being steel vs aluminum or serrated vs smooth, but the way the mechanism works. Give it a try before pulling hair out on all the other options. --Mike-- Chain Reaction Bicycles www.ChainReactionBicycles.com "SuperFly" wrote in message oups.com...

The newer quick releases don't work on horizontal dropouts. I reinstalled my Campy skewers and that solved the problem immediately. Neal

Use an old steel-handled Shimano skewer and ensure the cam is lubricated with a drop of oil.

I'd make sure the dropout alignment is correct (that is, their faces parallel to the central plane of the frame). Tom Ace

Adjusting the bearings and then tightening the **** out of the
quick-release is definitely the best solution. I have a steel-framed singlespeed that didn't have good bite with the locknut serrations. It took me a decent crash when my chain derailed to figure that one out. I use a old-school steel-handled Shimano QR and I have to yank on it pretty hard to get it off. Whatever you do, don't use any of the small late-model Specialized skewers. They're crap. Phil

The dropouts are almost parallel to the chain line which probably doesn't help. Try a drop of oil on the cam of the quick release. It can bind and prevent proper tightening of the QR. (Concerning other question: Adjust bearings a bit loose, such that tightening the QR compresses the axle enough to take up the play and give a very modest pre-load.) -- Ned Mantei Zurich, Switzerland
