I recently got Time Z pedals and am absolutely LOVING THEM!

However, about 4-6 times, when going up serious hills in like 1-3 .... my rear wheel "LOCKS" ... All I've changed is that I got the new pedals and have more power uphill now ...

I have to dismount, unlatch the tire, then re-latch it. It seems really tight when I latch it ... so the only thing I can think of is that the amount of torque I'm creating is forcing the wheel to move!

Any ideas? Had this happened to you before?

Any visible signs that the wheel has moved? When you say "unlatch" and "re-latch" I assume you mean the quick release lever, correct? I'm not sure how it could move in vertical drop-outs unless the wheel isn't seated all the way. Even then, I would think that the forward movement of the chain would pull the wheel forward or up.

Are you shifting while climbing? The only time I've ever had my wheel lock was because of chain suck.

Right, I mean quick release.

Basically, I'm chuggin' up a steep hill in like 1-3 ... while pressing pretty hard on my right pedal, all of a sudden the wheel LOCKS.

I dismount, look at the back. The tire is touching the left side of the frame. I undo the quick release, and the wheel goes back to normal resting position.

It's more like the left side is pulled "out" than any initial un-eveness

a couple of things i can suggest: try cleaning and greasing up the quick release skewer especially on the thread and cam/lever point. also clean up the dropouts (eg/ paint flakes). put everything back together and tighten up the quick release (but don't go overboard). go out and ride and see if it slips again.

If it still keeps slipping it might be worth using a different skewer (a mate had trouble with the stock skewer (a piece of crap) slipping on his fork so he change it with an old one lying around and has had no problems since.)

hope this helps!

The reason I say torque is 'cause we're talkin' about steeep stuff, like straight up root style ... not normal inclined driveways.

I'll give that a whirl this week. Thanks!

What brand of bike is this? I have had Specialized(plural), with the replaceable hanger that also is part of the drop out. The hanger would get a little smooth and the wheel would cock all the time esp when climbing.
On a personal note I had some Ti skewers and they were just to springy. Didn't matter how tight you got them on a climb or hard sprint the wheel might pop out. Swapped out for a nice steel skewer and the problem quit.

It's a 2003 Specialized Rockhopper ... I weigh in around 250 ...

The Rockhopper has the hanger with the plate that the axle nut seats against. Pull out your wheel and take a look at it. If it has wipe marks where the axle nut has slid against it, replace it. Other wise the wheel will keep shifting. Your shop might give you one as a warranty(might). You also might want to get a skewer that has a full steel end knob rather than the Shimano with just the insert, they are about $10.

Remove the qr and leave the wheel in the dropouts. Check to make sure the axle is not flush with the dropout face. Shimano qr's are a quality product and usually hold quite well. The lever should start tightening, ie you should feel resistance when the lever is straight out and in line with the axle.

awesome! Thanks guys!

It was the skewer. I brought it over to the shop and the tech knew what I meant. I wanted to be armed when I got there.

He threw in a solid metal one in the back, said I didn't really need one for the front at this point ...

I went out yesterday and didn't lock up once!

w00t!

Thanks again!
