Front wheel slipping

Hello,

My front wheel axle on the Karate Monkey sometimes slips and the wheel comes out of alignment causing the disc brakes to drag. The last time I was out I had to stop and re-adjust it 3 times, and I have the quick release pretty tight. I know this topic has been covered before but I couldn't find the right search words to find it. Has this problem been solved? The guy at the lbs was puzzled.

Thanks.

See the discussion about the fork drop out design in this thread.

I imagine a good quality QR like a shimano would probably help you here.

What BW490 said... and...

a) Make sure you're dropouts are properly aligned... LBS should have a tool for this.

b) Try a different skewer.

I had to 'face' the dropouts on the fork, and I'm using salsa flip-offs, so far no more problems

How do you face dropouts?

I fixed it with one of these:

Maybe I'm blind, but I couldn't find a tool that faces dropouts in the link you provided. The only facing tool I found is one that faces disk brake tabs. Does it also work to face dropouts as well, or am I totally missing it?

Drevil,

My mistake... I did NOT mean 'dropouts' in my original post, I meant the disk brake tabs. One word, one big misinterpretation

... I faced the disk brake tabs and used am using a salsa skewer. whewww...

Sorry for that, now back to the regularly scheduled program.

I really wasn't trying to bust your balls. I just never heard of such a tool, and was curious why someone would want to remove material from the dropout (unless the faces on each side of a dropout weren't parallel to each other).

No, you weren't busting my balls and I didn't take it that way. I just latched on to the previous thread (aostys dropout comment) and didn't realize I wasn't talking about dropouts

... No worries, hopefully chris can ride safely (soon)...

How much...

...was the Hope tab facing tool? Did you order it directly from them?

I have all my tabs faced - nary a chime running my Minis. I always have my LBS do this though because the Maggie Nanomat is prohibitively expensive.

I was referring to this - to align the axle dropouts.

Jl was referring to facing the disc brake tabs.

Two different things.

Do you really need to face your disc tabs to make the brake work? I thought they came with shims for alignment.

Back to the OP's problem, what does disc tab facing have to do with front wheel slippage?

Edit: Never mind...I see it's dropout alignment. Just the same, as flexible as the fork and skewer are I wouldn't expect any benefit from a few degrees of alignment perfection. That looks like a tool for repairing crash damage or cold setting a frame.

Dude needs a knurled steel faced skewer like a Shimano at least, and I wouldn't be happy without horizontal dropouts or V brakes to boot.

I use only Shimano skewers because of possible axle slippage. I have had Salsas move.

I have Shimano skewers but they're used. Do they ever wear out and need replacement?

The cams can wear and reduce clamping force.

Did you file off the fork's lawyer tabs? Keeping them is a good idea with disc brakes.

What are "lawyer tabs"? I haven't done anything to the fork but I got the bike used and I don't know if the previous owner did anything.

The raised lip on the dropout that make you have to unscrew your QR to release the wheel.
