BBracket size of Mongoose Switchback
I need to overhaul the bottom bracket on my winter bike which is a Mongoose Switchback.
I got the bike used so I'm guessing it's one of the first ATB designs, (late 80's), due to its relaxed frame geometry. Before I tear it apart, does anyone know what size the shell is?
I'm guessing it's a 73.
Thanks!
Jim
