Sorry Brian, couldn't find any specs myself apart from 120 mm wheel travel. I could look at mine but I am not planning on pulling the rear shock at this time, or even soon - I don't feel benevolent towards the old girl right now.
If the model can be identified, an enquiry towards the manufacturer may be beneficial, though I can't even remember the manufacturer. CRAFT disease rears it's ugly head again (and again, and again, and again).
Hopefully others will be more knowledgeable than I and can assist in short order...
