Re-dish wheel?
I have a powertap g3 hub laced with cxray spokes to stan's 340 rim. The freehub is 11 speed shimano.
I am going to transfer this wheel to another bike that is campy 10 speed. I bought a freehub and cassette. Will I need to get the wheel re-dished? (I am not even sure what exactly this means.) |
I don't think so. If so, it will be a very small amount. Sheldon Brown has a good and simple explanation of dish in his Bicycle Glossary, quoted below:
A bicycle wheel should have the rim centered directly in line with the frame. The forkends are symmetrical with respect to the frame, and the hub axle locknuts (or equivalent surfaces) press against the insides of the dropouts. Wheels should be built so that the rim is centered exactly between the axle ends on the hub. In rear wheels, the spokes attach to flanges which are not symmetrical about the centerline...the right flange is usually closer to the centerline than the left flange, to make room for the sprocket(s). When rear wheels are built properly, the spokes on the right side are made tighter than those on the left side, pulling the rim to the right, so that it is centered with respect to the axle (and to the frame.) Viewed edgewise, a rear wheel built this way resembles a dish, or bowl, since the left spokes form a broad cone, while the right spokes are more nearly flat. By extension, the term "dish" is used as a general synonym for accurate centering, even in the case of symmetrical wheels. |
Assuming everything else is the way it's s'posed to be, you should be good. "Dishing" is the process of centering the rim between the hub's left and right locknuts. Those haven't been changed so your wheel shouldn't need to be redished.

Assuming you are physically swapping the Free Hub "mechanisms" to the same hub-
It depends on the total length of the Free Hub. IF the DS lock nut ends up closer to the actual center of the rim, that much spacing would have to be added to the NDS and the wheel dished toward the NDS 1/2 the amount of added spacing. (one might make a case that it has to be "undished" that amount) |
Why change the freehub to go from 11 to 10? Unless you need to re-use the 11s freehub elsewhere.
Simply install a spacer on the back side of the 10s cassette, and you should be fine with no changes to the spokes. And, it is easier to go back to 11s in the future if you desire. |

IDK about your case , specifically, try it for yourself .. see how it goes .
I do dish adjustments to make lesser cost combinations work adequately .. like a 126 7 speed freewheel repair wheel, into a 5 speed freewheel 120 frame bike. & 5 speed freewheel wheels as a 1 speed freewheel wheel .. |
Okay, it sounds like put on the new freehub and if by eyeball the wheel is not centered or if it doesn't shift well, go for a redish.
