145 mm spaced rear wheel in a 135 mm hole

I am thinking about getting this set of wheels for a touring bike I am building for myself. the frame is a Trek 730 multitrack.originaly a hybrid,but full chromoly steel and a great ride for a big guy like me. Can the shimano hubs in this set be spaced down by 5 mm on each side? Or if not ,how bout 2.5 mm each side and spread the frame 5 mm? I had a set custom built around this set of hubs in late 98 and he built them to fit a 135 frame,but I am not sure how he did it.
If it can be narrowed evenly on each side,would it need to be redished to center the wheel? (I dont think it would,but there might be a detail I am missing),thanks for any opinions or answers

You can swap the axle to 135mm, but then you will have to recenter the wheel, increasing wheel dish. Kind of defeats some of the purpose of buying a tandem wheel in the first place. Provided your frame has enough crank and heel clearance, I would cold set the rear triangle to 145 and make full use of those very strong wheels.

You can get an exploded diagram of these hubs on the shimano europe web site by typing in tandem in the search box. I have thought of doing the same thing. you only need 2.5 mm space between the smallest cog and the droupout this will get you down to about 142mm. you can put a 138mm hub in a 135 mm space without bending your frame. you will then need to add 2mm dish to your wheel. If you want to get radical you can remove the 8 cog body and put on a 7 cog body this will get you down to 138mm without redishing your wheel.
