Hello again:

I posted before, and thanks to you kind fellows, I managed to finally get the rusted cotters off my old Raleigh Sprite 27.

(However, since I discovered the HAMMER before bikeforums.net, unfortunately I had to drill them out).

Now I've got the bottom bracket apart and am doing internet research about the 26 TPI issue ...

I'd like to use a square taper spindle with the existing cups/cones (they are in good shape). Where can I find a proper sized spindle? Any hints?

My BB shell measures 71mm,
the existing spindle is 136 mm.

My reading suggests a five or seven series spindle (letter code), but I cannot find a source.

Has somebody here already done something similar, and could help me out?

Thanks again!
