When you convert from 10 speed to 11 speed, you install a different axle that shifts the wheel. You need to have the wheel re-dished to center the rim between the dropouts. (For some bizarre reason, for which I do not know the etymology, The term "dishing" is used to describe centering the wheel over the hub.)

The simple explanation is that you need to (or have someone) loosen the spokes on one side and tighten them on the other side to pull the rim over. Then, you re-true it once it is properly centered.

Thanks exxxviii!
A good technician that I spoke with, wasn't supporting the dishing option. you think it can work well ?

The technician that you spoke with isn't good.

Yes, when you convert a wheel from 10- to 11-speed, you must re-dish. Here is a link to Zipp's conversion page for 2012 wheel conversions that specifies the re-dishing.

This is Very helpful! Thank you exxxviii,

I converted an older 10sp 404, using an aftermarket freehub, and didn't re-dish. It's off a little bit, but nowhere near what's shown in the pic up above. I can swap wheels without making any adjustments to shifting and it works fine. I do try to recenter the brake caliper though.

Similar situation with a set of older Reynolds wheels.

I think the need for dishing depends on how the conversion kit is designed. If you do not need to also replace the axle (like some Shimano hubs, I think), then the shift is only like 0.5mm (or nothing, if it is only a freehub body change). But, others shift the wheel a couple millimeters.

In addition to what has been written - the asymetric chainstay on your bike complicates things. Your best option might be a wheel that is not dished to the center of the hub, but instead is dished to account for the big chainstay. That's what you would have to do if the tire were rubbing.

Thank you exxxviii, Andy !

The extra material in the nondrive-side chainstay doesn't affect the centering of the wheel cutout. Dishing the wheel to the hub center will be just fine (incidentally, I just did this a few months ago when converting a set of American Classics from 10- to 11-speed for a 2012 R3. The new hub body and axle shifted the wheel 1.5mm if I remember correctly).

PSA: "Entomology" is the study of insects. "Etymology" is the study of word origins.

I'm just telling you my experience, which has been that a perfectly dished wheel in an S5 results in less tire clearance at the bulgy chainstay than at the skinny one. I have only looked at this on three frames though. Maybe it was different on your bike.

Too funny... thanks for the catch. I swear my mind said etymology, but my fingers typed entomology without permission. I have to go back and edit my post, because those types of errors drive me crazy.

Yeah, they bug me, too. Sorry, couldn't resist...

I agree... I had to re-dish mine too and all was good after that.
