I assume a 68 x 127 BB is what I need for my wife's Raleigh M30 mtn. bike. It is a triple crank Shimano dual sis 42-34-24
I have found one on E-Bay that is new and I want to get away from the non sealed BB cartridge that has the exposed bearings in a retainer cup if this makes any sense.
Please refer to my post on 1999 Raleigh M30..................
Thanks for any feedback. I hate that sort of BB that is on the bike currently.
