Rear wheel not all the way back in dropout
 
2 Attachment(s)
Bought this beater bike at a garage sale (I should really stop doing that). Needed quite a bit of work. The only problem remaining is that the rear wheel hits the frame if I set it all the way back in the dropouts. When I align the wheel straight it is forward in the left dropout as pictured. I’ve ridden it a bit around the neighborhood and it seems to hold as is, even jumped a few curbs on purpose w/o problems.


Pretty sure it’s not the wheel, seems true. I’m thinking it’s the frame. So do you’all think the wheel will hold as is? Or am I just asking for trouble? Bike rides really smooth BTW.

Thank you

Plenty of room there, wheel seems to be angled. Wheel or rim bent? Hubs tight? Proper sized wheel for frame? Tire too large? Couple more pics and info please. Frame and brand, current rim size and tire size?

1) does the frame has a fixed derailer hanger, or is the hanger clamped under the acorn nut of the q/r?
Clamped hangers usually come with a screw and a funny looking nut that fits in the dropout slot to keep the derailer in place when the wheel is removed. That tends to eat up 1/3" or so of driveside slot.
2) with horizontal dropouts, the length of the chainstays and dropout insertion doesn't have to be spot on. As a consequence, it may well not be.
Although rarely as offset as yours.
3) If it works, it works. Ride more, fret less

+1. A claw-mounted derailleur was my first guess, too.

If your rear derailleur is mounted via a "claw", as opposed to a hanger that's part of the frame, the claw itself and the nut that helps hold it in place take up a portion of the dropout slot on the drive side. The axle will be able to slide all the way back on the non-drive side, but not on the drive side because of the claw, so the wheel will sit crooked if you pull the axle all the way back on both sides.

The solutions are to either not slide the wheel all the way back on the non-drive side, or to put a spacer in the non-drive side dropout that takes up the same amount of space as the claw.

Why do you want the wheel all the way back in the slot? It's not necessary. Just set it so it's straight in the frame and the derailleur works properly and be happy.

Its A choice.. Its a long Slot Dropout, anywhere it is securely clamped is Adequate..

Wheel moves off center because the QR is not tight enough, to resist the pedal force pulling the chain.

Go buy new rear wheel with track nut and problem solve!

Ditch that rear QR wheel, its not gonna work with your current horizontal dropout, obvious!

Is this statement in jest or actually thought as correct? Millions of bikes have had horizontal drop outs and their rear wheels were held in place perfectly well (assume proper tightening of the QR).


If you're advocating for the OP to go single speed/fixie just say so, don't go around the block and blame a QR for a problem that doesn't exist. The OP stated the QR holds the wheel where ever he locates in within the slot.


Remind me of the distraction with alternative facts that we see elsewhere... Andy.

???

Why? OP has a proper, enclosed cam quick release, not a modern open cam QR intended for vertical dropouts. Properly tightened, the OP's current skewer should be more than adequate to hold the wheel in place.

The OP doesn't state he has a problem with the wheel staying in place. Just that the wheel is crooked when fully rearward in the dropouts. I would just put the wheel straight, tighten the skewer, and call it a day regardless of the axle position being symmetrical wrt the dropouts.
