Bike skills (endos, hops, etc) - possible without cages/clips?
I'm just getting more involved in the MTB sport, and I'll eventually upgrade to cages or clipless pedals. however, I do enjoy the challenge of using my mega-heavy Gary Fisher steel bike with no really fancy parts, kickstand, rear rack and all and powering the uphills blowing past some of the ultralight MTBs I sometimes see out there on my trail.
I was wondering if the technical skills such as endos, hops and such are possible without clips or clipless. I'd get started on 'em right away if so! I just can't really see how to do a hop without being able to pull upwards on the pedals, but some of you expert riders always have such surprising skills....
