Hi there I have just measured the inside were you mentioned and its defiantly 68mm now I have just measured my bottom bracket in total length and I get 126 mm without the threads so that's 68-126 mm that seems a little big I mean ever since I had this bike its seemed like an unusual size when I replace the unit is there some sort of washers/spacers available just encase its a little long as this bike was second hand so I can't be sure what has been replaced here is were I measured from
If this is indeed correct which I have checked 4 times then the measurements are 68-126 mm can you recommend me good affordable bottom bracket please from eBay UK or Halfords and I will buy it tomorrow :-)
Cheers
Joe
