Rear wheel slipping forward
 

Hi guys, I have been having a problem with my rear wheel slipping forward. Every once in a while it happens when I come to a stop then stand up on the pedals and put some power down to start moving again. I have the dang rear quick release cranked down really hard so I dont get it. This frame is made for 125mm rear hub and I have a 130mm hub on it. Could that be the cause?

The QR may not be up to the task of keeping the wheel in place and cranking up too tight can affect the bearing set in the hub so perhaps trying a new QR might solve the issue.

If your dropouts are misaligned this might also be contributing to the shiftiness of the wheel.

Older internal cam q/r work much better re clamping power than modern external cam types.

You just don't need much clamp when using q/r's in a modern vertical dropout

The qr's are new lightweight aluminum ones that came with the wheels. I guess its time to look into some alternative qr's

Make sure the axle is not too long.

I had the same trouble and am afraid it could be not only the QR but also the other hubparts. Modern roadhubs are made to be as light as possible and fit into vertical dropouts. They use soft alloys on all parts of the hub contacting the dropout. Maybe you could change to steel washers and steel qr. It got better when I used an old Campagnolo QR but still happened once in a while.

Cool, thanks for the help guys.:beer: Ill check around ebay to see if there are any decent old campy qr's for sale.

Shimano's are very good.

Yup, that's what I'd check. I'll be you have a wee bit of axle sticking out of one side of the dropouts. A washer between the QR and the outside of the dropout will solve that problem.

Hey guys, I just wanted to update this thread. I grabbed an old shimano qr off of my cannondale and it worked great! Even under high torque situations it doesn't budge. Thanks again everyone for your help. :)

I have had to do this with any forward facing dropout frame. The new skewers must only be made for vertical DO's. The older QRs are great. I think Sheldon Brown has an article about this exact issue.

This is a common problem. On each of the last two Saturday morning rides with my club, I have pointed out a rear tire which was about to rub the left chainstay.

I ride a single speed mountain bike and have the bruises and scrapes to prove that not only does your wheel get skewed, your chain comes off. I was pushing hard up a long steep hill and the chain came off right at the top of my down stroke and now I've got pedal bruises on both legs, I've got skinned knees, a sore wrist and a skinned elbow. I got home and one of the links in my chain was bent at a crazy angle. I had to walk all the hills on the way out.

Great thread. I never realized there was a potential problem matching new QRs to horizantal drop out frames. Now I know. BTW, if the rear hub is a 130, any old MTB 135 QR will work with room to spare.
