The bike is a mid 1980s Raleigh road bike, the bottom bracket is on its way out and needs replacing. Its stamped "Japan Tange 1.37 x 24T K1". The spindle is square but I cant see any other markings which might indicate how long it is. Does anyone on here have any idea what is available these days which will fit, if anything? I dont mind if the spindle is a different shape as I'd like to fit lighter cranks anyway.
Thanks for any info.
