Question for Pinarello owners regarding seatstay/rear wheel(6 posts)

Question for Pinarello owners regarding seatstay/rear wheelanzoni
Oct 7, 2003 3:48 AM
Hi!
My Pinarello Marvel has two screwholes on the rear seatstays. I've recently seen other Pinarellos having two screws/fillins (chrome) here in pictures. Anyone know what purpose these holes serve? I am having some problems with my rear wheel under full airpressure touching the seatstay. The holes are seen on both sides, just over the quickrelease.
Thanks,
Glenn

Those holes are for small adjuster screws that most european bikes havethe help cenetr the wheel in the frame and adjust how far back in the dropouts you can set the wheel. If the rear triangle is straight, the wheel should line up fine, if pulled all the way back in the dropouts.
If needed any decent shop should have these screws. i would expect a wheel that is not sitting straught to rub the chain stay, not the seat stay. Is the wheel dished properly ?

Thanks,
the problem is really that the tire (full pressure) sometise rub the rear fork. Seems to me on pictures that some pinarellos have their wheel lower in the back. I was wondering wether those screws were the reason for my problem.

Do you mean it's rubbing the frame right under the rear brake ?
What size tires do you ride? I have a Prince & ride 23c's,
It looks like 25's would fit, but 28's might not.
I also have no problem w/tubulars.

Yes, thats exactly what happens. Tire size is 700*23 (gp3000)on Ksyrium SL's. Should be stated that it only happens under maximum airpressure, but I should be able to have what pressure i want, shouldn't I? My idea was that it may lower the wheel a bit with those screws, but I'm not sure.
get the screws, it will solve your problem.Qubeley

The purpose of screws are:
1.adjust wheel base(very little effect though).
2.make sure the wheel is aligned.
Those screw shouldn't be hard to find, it's the same size as those you use for cycling computer mounting bracket.

Alternatively, just don't put the wheels all the way in, the wheel are not supposed to be all the way in anyway..
