How many beginners don't understand how a QR works?

Hang on a minute, don't you ride a fixie with no QR???

Guilty as charged, only 2 of my bikes have QRs

But really, it doesn't matter, unless you have directional tread on the tyres!

I still don't understand why directional tread has a bearing on what way round the QR should be. Please enlighten me.

So the lever is on the non-drive side (assuming standard road bike with no quirky reason nor gimmick that dictates otherwise), whilst the directional tread is aimed in the right direction.

I only mention it as I think for many it's a reasonable assumption that one can just whack in the front wheel whichever way around after fixing a puncture or whatever. It wouldn't really matter that much, unless one had directional tread.

Okay, assuming the tyre has been fitted correctly, why is it functionally important that the cam is on the non drive side?

Agreed!

^^^^
Just answered my own question by going out to look at the bike! Things are rather cluttered round the drive side, with the derailleur and cable etc, so I guess it's far better to have the cam on the non-drive side.

 

[Globalti]

Yes, and it must be facing up and forwards into the frame triangle while the front QR must be facing up forwards of the fork.

Don't ask why, just do it right.

But before we discuss sides we need to agree which side is left and right?
As you look at it or as you sit on it?

If the tyre is on the wrong way then you have to take the tyre off and put it on the right way, not spin the wheel round so the QR is on the wrong side!

I bought one pair of hubs once and there was something about their direction in the manual, think it was Dura Ace track hubs...

In short though, the QR never goes on the right, it's just the way it is, it's the rules!

" If the tyre is on the wrong way then you have to take the tyre off"

This only applies to disc hubs, you can put a normal road hub anyway round, and insert the QR from whatever side takes your fancy.

Dura ace track hubs don't have QR do they ?

Queen's Regulations

(first published in 1731 and known as King's Regulations when the United Kingdom has a king) are a collection of orders and regulations in force in the Royal Navy, British Army, and Royal Air Force, forming guidance for officers of these armed services in all matters of discipline and personal conduct. Although originally a single set of Regulations were published in one volume, by the mid 19th century there were separate editions of Queen's Regulations for the Navy and the Army, and there is now one for each of the United Kingdom's armed services.

HTH. But if it doesn't, it's a Quick Release. The wee lever that helps hold a wheel in place. Unless of course you have nuts.

I know this may sound strange but isn't a QR short for Quick Release (ar thats better Though perhaps sometime a slow release is better) But I thought perhaps misgiudedly that if your looking at the bike from the front then the Quick release assemblies go with the Q R lever on the right hand side mainly I thought so it's nowhere near the derailleuer mech. Of course I am only going on bikes I've looked at and how mine were when I first got them from the dealers But what do I know

Ow right, Can I join in? Just stick them on any side, who gives a fck!
