Hi everyone i went to Halfords today to get the new Bottom bracket the size i measured was 68 x 126 but that was wrong as he measured it at 122.5MM he got me the correct bracket which was a VP-BC73 68 X 122.5 Square which cost me £9.99 and a B/H/brakt Shimano tool i installed no problems although i didn't have enough grease as i would have wanted most of which was smeared from the old bracket the installation went fine no wobbles used my wrench to get everything nice and tight and everything is perfect now thanks everyone for there replies i will keep these measurements for future use when this one hits the dust thanks guys
