rear wheel alignment

[lackofgrip]

I noticed the other day that my rear wheel is closer to the frame on the left of the bike, so I undid the quick release and re centred it, only to find the same problem after a quick ride.

Does anyone know why it's doing this?

It's a focus Cayo full carbon so I don't want to overtighten the quick release. How tight should it be and can the body tension screw on the derailler effect this problem??

Please help as it's starting to bug me.

Tighten up the QR .... simples ... The QR should be tight enough to stop the wheel pulling over ... experiment... or use bolt on rear wheels as i do ... 45 - 50 Nm torque

Closer to the frame but straight, or twisted round a bit?

Is the frame symmetrical?

It looks slightly off, plus I dont want to overtighten the QR or would that break before the frame? The wheel looks straight when I spin it ie it doesn't wobble like a wheel that needs trueing

I guess what I'm saying is wheel looks slightly kitty cornered in frame and I can straighten it by reclaiming QR maybe I'm not doing it tight enough. Its worth pointing out that when I spin the wheel it stays same distance from brake pads on both sides

Others may correct me but I feel that you need enough pressure on a Qr to be uncomfortable when doing it. Your hand that is!

That's what I thought but don't want to give it too much with it beig a carbon frame

The dropouts will be alloy, they will be strong enough to do up the Q/R so that the wheel doesn't pull over.
The Q/R needs hand-grip pressure to be tight enough, not a couple of fingers...you will feel the Q/R cam "go over" when its tight enough, ie it goes past its tightest spot, thats what stops it rattling loose.
Line up the lever with the chainstay, grip stay and lever to tighten.

I know virtually nothing about carbon frames but I presume that the dropouts (the bits the q/r grips) are metal inserts so you can tighten up the q/r without fear of damaging the frame.

There are various things that can cause the wheel to slip, loose fastening (q/r or track nuts being the most obvious) A wheel slipping can also be the symptom of a broken axle - the q/r will keep it all more or less together for quite a while. Then there at least on style of q/r which is OK for keeping a wheel in vertical dropouts but is useless in a horizontal pair.

(I see others have posted more quickly along similar lines.)

cheers for all comments guys, I'll try tightening up in line with chainstay I was just petrified of damaging dropouts

You could always go to an lbs as well...

Are they not vertical dropouts, then?

[The Mechanic]

Just what I was going to say. If the frame has vertical dropouts, which I am sure it will have, then the wheel should not pull over even it the QR is open apart from a very small tolerance in the dropout. The ethos behind vertical dropouts is that the wheel slots in and that is it. No fiddling about with alignment like with horizontal dropouts of the past.

[lackofgrip]

It's vertical dropouts yes.
