Although I have never noticed it before, it is clear now that my entire rear wheel is dished about 1.5-2mm to the drive side.

It is a Bontrager Race Lite. I could pull it back but don't want to do it if this is common. Is this supposed to be the case?

Note: I am not talking about the angle of the spokes being different on the drive side. I am talking about the rim being closer to the break pad on the drive side when placed on any bike I have tried it on.

No.. it's supposed to be centered...

jerlwe

he's definitely correct, right down the middle

Wait... is the rim off center in relation to the ends of the axles, or is it off center in relation to the flanges where the spokes attach. If it is (a), then something is wrong with your wheel (although I don't know how it could clear you frame/brakes like this...). If it is (b), then this is normal. It must be like this because the cassette gets in the way.

Thanks guys. The case is definitely (a). I will move it back to center. How wierd that the entire rim is this way (off center and still true). I can only surmise that it was built up this way.

Check with a dishing gauge and get back to us. It's the only way to rule out other factors.

Mine were the same way... I noticed when I would swap the rear out to put it on the trainer and the brake did not like up. Mine was about the same amount off.

Sawtooth

good idea. I don't have a dishing guage but I have a wheel true stand with a single sided lateral indicator (maybe that is a dishing gauge). If I mount it on one side, pull the indicator over the rim, then flip the wheel to the other axle end, shouldn't I be able to get the same knowledge?


Hmm, very interesting....Perhaps I will wait to see if others' have the same issue before I pull them back over. Did you pull yours over to center?

I've used my 1-sided truing stand as a dishing gauge.

The rim should not be dished to one side when installed inside of the drop out, it should be dead center. However if you are referring to the offset spokes, and one side of the rim being more slanted than the other, then yes this is intentional because the drive side receives more stress than the non-drive side, obviously.

What year is your wheel? Does is have the paired spokes? I had an 08 set with the paired spokes and that thing would NOT stay true for love or money. It was also difficult to get the dish right for a very inexperienced person like myself. After several returns to my dealer for re-truing they finally replaced it under the Bontrager 5 year warranty. It was replaced with an 09/10 model and Bontrager no longer uses the paired spoke method....I wonder why?

Also, my original wheel appeared to be laced wrong wherein the spokes never overlapped when crossing each other just outside the flanges. I always thought that was a requirement because it adds more strength when the spokes are interlocked like that basically extending the flanges. Just a heads up to this potential problem.

You know... I should, but I haven't bothered to yet. I had to send the first rear back due to a bad hub and was waiting to see if this one would hold up. So far so good after about 3000 miles so I will probably re-dish it soon but it is not causing an issue with clearance or anything like that in the short term.

I had the same issue with my Bontrager wheel. I mounted my new powertap wheel and noticed that the brakes for the Bontrager wheel were positioned differently. So I measured the dish and it was off.
Took it to the Trek store to get it centered only to be told that the wheel is perfectly fine Friggin amateurs.

If it's 1-2mm I wouldn't mess with it.... you're more likely to mess something up trying to dish it perfectly and it really isn't hurting anything now correct? That is assuming that it's in good true/tension now. I'd just wait until it needs truing and then fix it.

Any chance this wheel has had the cassette body changed from campy/shimano, etc? The freehub bodies are different dimensions and on some hub designs this can change the dish by a millimeter or so. (Again though, nothing to really worry about unless it is causing you problems.

Maybe you are right....I have been riding it for 2 years now and not even noticed. I only noticed this weekend because I am running 25c tires and tried to put the wheelset into a pretty tight frame (tarmac pro). It is not like it is slowing me down or affecting my handling all that much;.......right?

BTW, I bought the wheel used so it may have been swapped over to Shimano in the past....not sure.
