Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Threaded Tube Stem/Wheel Direction?

Couple of stupid questions...

I got my Reynolds Alta Race wheels today and went to put the tubes in, the threaded tube stems don't fit.. should I just file the hole a little bit or should I be using a threadless tube?

Also, how do I know which direction the front wheel should rotate, or does it not matter?

Hmm I would probably just file it a little...but I also prefer threadless valve tubes so it is a little bit of a toss up.

The wheel should always spin clockwise when viewed from the drivetrain side of the bike......

yeah they are presta stems, threaded.. the wheel questions is more of which way should I put the quick release lever for the wheel to spin the correct direction. It's easy for the rear wheel cause the cogs are on one side but the front wheel doesn't appear to have a way to determine the direction it should spin.

the QR should be on the same side of the bike - front and rear wheel as I understand it. Of course, you can pop out the skewer and put it in the other way . . . so I have no idea of which way a front rim should spin . . . or that it matters.

If you haven't already, do yourself a favor and replace the rim strips that come with those wheels with some quality rim tape (Velox is good but I'm sure others will work too). Make sure it covers the rim from flange to flange so it can't shift around. I had tremendous problems with the stock Alta Race rim strips.
Never even thought about the front wheel direction issue. I hope it doesn't matter....

Front wheel direction really doesn't matter, but...

Place it so that if there is a logo on the hub it can be read "right-side-up" from the riders position.

Place the skewer lever on the left side (from riders perspective, or "bike non-drive side") of the fork.

If there is no logo on the hub then look for a single sided rim decal. If there is a rim decal that is only on one side them place the wheel so that the decal is on the drive-side of the bike. - Note - If this doesn't match the orientation of the same decal on the rear wheel then just match the rear...and find a new wheel builder - it's the details folks.

Is there a reason for this? I actually do the opposite, for the not too important reason that it ends up on the same side as the brake release.

Just preference. I run the QR on one of my beaters on the right, because the rear wheel doesn't have a QR so I only look at the drivetrain side when I'm adjusting things. Makes no difference.

Well...I don't know of anything official, but here are some possible reasons for it.

-Rear wheel has to have lever on Left so that it doesn't interfere with derail, drive-train, etc... Front should match.

-Wheel changes done in race by mechanics. These mechanics are probably right-handed for the most part. It is probably easier for most right-handed people to close a skewer lever with their right hand (in a race situation). Left hand doing the supporting of the bike will naturally be towards the top of the fork (near the brake)....really close to the brake caliper quick release.

Just some thoughts.

Want another one?

Unless you have a radial front wheel, check how the spokes leave the hub. Install your wheel so that the front spokes match the back.
