I think Suntour made some interesting stuff in that era. I’ve got one of these I swapped the cage with on an XC mech to better suit the build. Straight swap so easy to put back if needed.
"The LePree I remember was the version introduced in 1985 on Nishiki models. It had three pulleys to achieve a 42T of chain wrap. It had been developed in conjunction with Nishiki and as a result, Nishiki had one year exclusive availability on the three pulley version."
42T of wrap is a lot, apparently because mountain bikes were becoming a thing.
