IRO Hub. Converting 130mm spacing -> 120mm. Is it possible?
Hi, I just got a new track frame with normal 120mm rear spacing. Now I wonder if is it possible to convert my rear IRO hub that I actually have on my road conversion with 130mm spacing to 120mm.
It looks like there is a 0,5cm spacer on each side of the extremes, so removing them would give me the desired 120mm. It makes sense as the hubs should be the same except the longer axle and spacers on the 130mm version, however I've never dissassembled a hub so I don't really know if that would be possible. I'm also looking for a quick & easy solution, machining down the spacers is not valid for me.
Just asking in case anybody knows before I hack it and check it myself....

yeah, just remove the spacers. Take off the lock-nuts (those are the nuts on the outsides of the spacers) and take the spacers off. Then put the lock-nuts back on. Ta-da!

you have to remove the same size of spacer on each side
if you can.. it's better to control with this tool
the first time i've broken an axle cause i had removed the spacer only on one side

that's the quality process..
sometime the spacers aren't of the same size on each side so you have to cut them and control the alignment of the wheel
in this case this is the interest of a wheel alignment gauge

if you think they aren't the same size, just stack them up like quarters when you're done to compare..

Mission accomplished! 
The only problem is that now the axle looks really long on the new frame, but I don't really care, and I prefer not to cut it just in case I put the wheel back on a road frame some day.

it's good to know
or it's a Misunderstanding (my translator don't know the term "dishing") but i understand the terms "remove spacers" and "alignment of a wheel"
