Hello killjoyken
From memory they were Suntour XC pro greasegaurd threaded units at 1 inch size. I know they were in 91.
Do a search on here for ameybrook and PM him as he has rebuilt a 92 M2 S Works Ned Overend replica.
Pretty sure its a 1 inch but best to check.
Well, I took of the stem and measured it at 1". I was hoping to put on a newer susp fork, but it looks like I'm stuck with the Manitou SX that's on it. I hope it holds up!
