Shimano Biopace axle length.

[orbeas]

Does anyone know the correct length of the bottom bracket axle for a Shimano Biopace triple chainset - cannot seem to see it listed anywhere not even on Sheldon Brown ..

Depends on frame and crankset - 'biopace' just referred to the chainrings and not the crank arms

122mm, 125mm and 127mm

I bought a 122 for the 80's vintage Shimano Deore crankset I put on my Miyata hybrid.
