How much can you re-dish?

KBH said:

Wanted some opinions before I attempt this:

Have a rear wheel set for 135mm rear spacing. It has an 8mm spacer on the non drive side that I'd
like to remove for use on an old frame with 126mm spacing, so I'd need to re-dish by 4mm. Can this
be done with the existing spokes? Should I loosen all the spokes and completely rebuild, or just
start by tightening the drive side?

Thanks,

probably not, it really depends on just what length spokes where put in on the build, in this case i
doubt you can. most of the time you only have a couple mm of thread left after tensioning. take a
look at the nipples in the rim holes, the threads can only come through the top by ~2mm then they
bottom. you need to leave a few threads in the nipples on the nondrive side as well!

never adjust the true (on a properly tensioned wheel) by tightening first! lossen the away side then
tighten the toward. on a dished wheel the non drive side needs ~1/2 the turns as the drive side.

Depends on how close the existing spokes are to having the full depth of the thread already in the
nipple. If there's a millimetre or two to spare then it should work ok. I successfully went the
other way with a rear wheel - got a longer axle and spacers from Bullseye and redished a 126mm
7-speed Bullseye hub to 140mm 8-speed for use on a tandem.
