was having a conversation with a weight weenie friend who wont upgrade to rear suspension because he says it adds extra weight!
Anyway, ignoring the fact that the suspension (upto a point) could actually help him on climbs on rocky terrain, surely if you ride a heavier bike your muscles / fitness just improve to compensate for the weight, so after a about 6 months of regular 2x a week riding you'll be about as quick as you were on the lighter bike?
