    So, bought myself a used Focus Culebro tt frame nice and cheap as the bb threads were stripped, thinking I’ll stick a threadless bb in an away I go.

    Only problem is I’ve no idea what axle length I need. Have been hopelessly searching the Web to no avail, can anyone help?

    Thank’s in advance

    Axle length is more specific to the crankset than to the bike. For instance I know, having fitted a lot of them, that a Shimano FCM 171 takes a 122.5mm BB.
    So, start at the crankset, not the bike. See how you get on. 🙂
