Hi there, I'm a bit new to this so bear with me... I want to change my 3 piece bottom bracket on my fixie project as no matter what I try there is some play. I want to change it to a sealed unit so have looked online and obviously the standard is 68mm but according to my tape measure mine is more like 70mm or even 71/2mm which I know is probably not possible. It's an old Sun Worksop frame so not sure why it would follow a foreign format. I'm worried that if I buy a 70mm one it won't align with the thread.
My question is: Can I get away with putting a 68mm one on there and tightening it up or will it not work? My crank is branded "Etc" but seems to fit most tapered spindles.
Any help would be much appreciated.
Thanks.
