Unfortunately I have two of them: one is on my son's (formerly my first race) bike. It is fairly ground down due to several crashes by me, but it is still working like a champ. The second one (actually a complete Suntour SP drivetrain) I have still new in boxes as spares. I say "unfortunately" because I will not sell them, sorry.

But, I know I have several worn pullies in my parts box, I will check tomorrow if any are for the SP and if they have the bolts.
