I have been riding since 92. The standard for wheel QR's has been to have the lever on non drive side of wheel. With disc brakes I like having the lever on the other side, away from the disc. is there any drawback having the lever on the same side as the derailer??

There is a standard? Weird I didn't even know. I run it on the drive side. Never did it the other way :D

It's supposed to be run on the left typically. But I don't see any reason you couldn't run it on the right. I'm not really sure what advantage you'd have, but whatever tickles your pickle I guess?

Want to avoid touching the disc("they" claim by touching disc, hand oils can cantaminate the pads) also could be hot if changing a trailside flat, and they are sharp. ha ha

if it doesn't get in the way of the der. you can go for it. im running discs with the QR on the disc side though, no problems.

We switch all of the QR's on our Disc equipped hybrids and comfort bikes as those customers tend not to care about the tech mumbo jumbo. "I had a Schwinn back in '42 and I could fix it - no problem." They see it set up one way and just assume it's right - kinda like valve caps you don't need them but god forbid you forget one. :rolleyes:

Bryan - you really don't have a clue do you? Never had a contaminated pad? Never burned your knuckle on a hot rotor fixing a pinch flat? I didn't think so.

I don't get flats often enough to justify that, nor have i ever had contaminated pads, either.

Yes you do need them. They prevent the dirt from getting in to the valve and save you 5 dollars ;)

I've switched mine around to the Drive side, only because of the potential of touching the disc when opening or closing the lever for either contamination or heat reasons.

I run them on the disk side. I wear gloves most of the time because I get cold hands and for safty so it doesn't matter if the disk is hot and there is no risk of contamination. I don't really think it would be an issue if I didn't wear gloves I could easerly open the lever without touching the disk and a little hand contact on the disk has never contaminated mine and by the time I get all my stuff ready the disk will be cold anyway.

Never new there was a proper way side, just put them on the left of the bike because the rear one fits nicely under the chain stay and the front one fits nicely up the fork leg.

Yes you do need them. They prevent the dirt from getting in to the valve and save you 5 dollars ;)Unless it's a blow out which would cost you the fiver anyway (or if you let all the air out) there's normally enough air in the tube to blow the little bit of dirt out especially if you fill with the valve at the top. Valve caps protect the tube from being abraded in the box. That's it, that's all they were intended to do. :rolleyes:

from Sheldon Browns site:
Valve Cap
A metal or plastic screw-on cover intended to protect the innards of a tire valve from dust and other foreign matter.
In the case of Presta valves, which have non-removeable, built-in caps, external caps are unnecessary in use. The purpose of these redundant caps that come with Presta tubes and tubulars is so that the pointy end of the valve won't puncture your spare tube or tubular while it is rolled up.

These caps are actually dangerous if you ride tubular (sew-up) tires: Should your tubular come unglued and roll off of the rim, with luck, you will be able to roll to a semi-controlled stop on the bare rim. If you have a cap (or Schrader adaptor) screwed onto the valve, the wheel will only roll until the captive tubular bumps up against the frame or fork, then the wheel will lock up, and down you will go!

Right, but not everyone run's Presta valves.

Why cant you just answer the question without bashing someone??? http://www.dirtpassion.com/fawk.gif I guess you cant detect sarcasm.

To answer your questions, No I have never had a contaminated pad, Yes I have burnt myself on a hot rotor. Jim Thorpe PA, wet, steep technical Downhill. Had a stick get caught between chainstay and tire, reaching for it, burned my forearm on the rotor. The main reason I asked the question is with the qr closed, it is a fairly tight space between the qr and rotor, looks like a place where A stick or tree limb can get stuck. Before you ask, no I have never had a branch grab a qr, But my best freind had a branch grab a barend at 40mph. severe road rash on his legs, pebbles having to be scrubbed from under his skin on his back, and a rash with bone visable on his elbow were the result of the crash.

Bryan You read this post:

Bryan
and tell me it doesn't look like a troll. With the "they" and the haha what the heck are we supposed to think? It didn't look like "sarcasm" it looked like you responded to a question that you didn't like the answer to.

What was there not to like??? I wanted to know if ther was any drawback to the qr on the other side, the question was answered. Done. You chimed in with the "you dont have a clue" comment. "They" was refering to hayes and avid stating to not touch the rotor. I used the "haha"' rather than a smile beacause I replied using the "quick reply". I was hoping to get some feedback and opinions on the subject. Not be flamed.

And I answered you in the first part of the post. The "you don't have a clue" was realted to your SECOND post which I already explained my perception of. Heck I didn't even look at who posted the original question (didn't really matter) I just answered it and responded to someone I thought was bashing not realizing they were the same person. Get over it.

I'm afraid that some members of this forum got a bad habit of calling people trolls without any reason. So, Bry 03 cobra, let them think what ever they want and not lower ourselves to their level by arguing with them.
