    Quick search says its a 68mm square taper axle (110mm long). If you look at the threads - is one left handed and one right handed or are they both the same??

    hi Paul,

    they both came out anti clockwise, both the same :?

    cheers

    oh ok - i was expecting you to say they were opposing threads as the 1.37x24 means 1.37inch x 24 threads per inch. This would be commonly called an "English" or BSA bottom bracket with the drive side having a left hand thread and the non-drive side a right handed thread

    i may be wrong with the thread directions! I have probably described something that doesn’t exist, i will have to retry :)

    lol ok Nick. if it is opposing threads then you simply need a pretty cheap to buy square taper BB - size 110 x 68. Something like a Shimano UN54 will be £15 to £20 and last years
