First, I haven't bought any of this yet. I'm trying to figure out if this works. I have a frame with 126mm spacing at the rear and italian threaded bottom bracket. This is what I'm looking at buying if I can make it fit:

Shimano UN54 70x107mm italian bottom bracket ($20)
Pake 165mm cranks ($60)
Mavic CXP22 wheels, Formula Hubs ($139)

Problem is the hubs are for 120mm spacing. Do I need a different hub? Do I have to buy a longer axle and spacers?

Will that crank/bb combo match with that hub for a good starting point for my chainline? I can get the bb in 110 or 115 also.

Thanks for the help!

Sheldon Brown has info on frame bending..

Also he has one's on chainline. Basically you need to mount your crank and do the measurements, we can't really tell before you do that.

Chainline has nothing to do with the frame - it's a measurement of the line between the chainring and the cog which should be 42mm or thereabouts. You need to fit the frame to the hub, either by bending the frame to 120mm (which should be fine if steel but not if aluminum) or by adding spacers between the cone and the locknut on the hub (3mm on each side, obviously). get the 107mm BB which will give you the right chainline for a track hub.

Thanks for the info and help. I'll go do some more reading.

If it's steel, just put in the hub and crank down the track nuts. It'll bend enough. If your really paranoid, you can get some 3mm axle spacers, but it really isn't worth the trouble
