malvern star (sportstar) bottom bracket solution
Hi folks, I've recently taken on a sportstar frame, late 70's early 80's at a guess, which seems to have an annoyingly unique BB. no thread with locking tabs. the bb itself has a lockring on the non-drive side only and it's a cotter pin design.
the bb I have is still useable so things aren't desperate as yet, but I'm spending alot of time on this bike and I'd like to fit a sealed square taper to give me a wider and lighter selection of cranks. anyone out there had the same problem? Is there a solution?
