Hi folks,
Not 100% sure but i recall a similar inquiry (here or somewhere else??) and i think Suntour pulleys will work for your intended application. Check it out with a 'ye olde bike shoppe' pro or someone with a Sutherland's though ... im often wrong & am no Sheldon Brown when it comes to bicycle engineering or ingenuity, but I just gotta hunch ;-)
ciao,
