I recently picked up an mid 80's road frame with 126 spacing. I've ordered a Suzue Basic/MA3 wheel from harris cyclery and now need to buy cranks and a bottom bracket. What spindle size do I need to achieve correct chainline?

Rear spacing doesn't mean anything because the axle spacers(from 120mm to 126mm) will on the outside of the cog.
Any matching track crank/BB should give the correct chainline since the Suzue basic is a track hub.

The track hub will have a 42.5mm chainline (center of hub to chain) which will line up almost perfectly with a standard road double crank's inner chainring position. Using a 110mm BB with a double crank should put the inside ring at approximately 43'ish mm which is basically spot-on for a chainline.

A typical track BB has a spindle of 109.5mm, which is very close to the 110 mentioned above.

I'm using a 109.5mm BB, tapered, on an old Sugino 175mm double crankset. The fixed cog on the Suzue basic hub falls just about perfectly on the inner ring position, but the BMX-style shimano freewheel on the other side falls just about perfectly on the outer ring. So, I run 2 rings, a 45 tooth inner, and a 42 tooth outer, with a 16 fixed cog and an 18 tooth freewheel. My short-lenght horizontal dropouts can't handle a lot of difference in chainlength..
I like it. All kinds of possibilities. (nm)TFerguson
