Hi guys,

Im redoing a Sekine (japanese bike made in Canada) and I wanted to change the old bottom bracket system with a sealed one. However, its a 70 mm with an english thread. Those are impossible to find (70 are always intalian thread).

What is the best solution (I would like to avoid to have it faced) to fit a 68 mm or a 73 mm ? Have someone had try any of those and what was the results ?

Thanks
