I had a RockCombo for several years, however, I would pick my 71 Paramount over it any day on just about any condition trail. The RC was kind of funky to me…very heavy and felt like you could go over the bars going down steep inclines ( I was borderline too tall for the largest size). I did go over them once on a sudden emergency stop…I landed on my feet in front of the bike…the guy in the car I avoided got quite a show! Got rid of it shortly after. I ride all my bikes on gravel and the Paramount did fantastic at Cino a couple years ago. 32s help but I take my 28mm clad Rivendell on the flat gravel rail trails here in Seattle all the time.
