I hope this isn't too obvious to ask but I'm trying to find out what the rear axle spacing is for a 1990 Wicked. In the mid nineties I switched from the stock Suntour XC pro rear hub to an XT 8 speed, so for the last ten years I've been running a 135mm rear hub. It shifts OK, but I suspect it was originally built for 130mm hubs and would shift better if I got it back to the original chainline (I'm still running the stock XC pro cranks). I'm also wondering if the switch (from or back to 130mm) will call for a frame re-alignment.
