Ok, perhaps against my better judgment I bought an old steel crankset for my Raleigh town bike build. It's shiny steel and has the heron emblem as one of the arms and looks nice - and it was pretty cheap on ebay so I took it!
Anyway, I need to fit it to a frame that was designed for a cotterless crank and has a 68mm BB shell. I guess that the BB shell design has remained more or less constant for donkeys years, so would the cups etc for a cottered crank be the same as for a cotterless model, with just the spindle differing?
If I have a cotterless crank that fits then can I simply swap in the right length spindle instead? Are cotterless and cottered spindles the same diameter? Please excuse my ignorance in this matter!
Cheers, Gareth.
