I rode Leb a couple weeks ago on my 29’er hardtail. I had about 15 PSI in my skinny Maxxis Ardent 2.4″ tires, with rear tubeless. I’m 150 pounds. Since the intermediate loop was packed pretty well and reasonably wide, I thought I’d be fine. NOT.
If I didn’t stay in the hard center, the softer edges of the packed area would often derail me. I kept thinking “lean the bike more” and “keep your eyes ahead.” I tried standing up more, then sitting down more. Nothing worked. I then ran into Bob Shepherd and a small gang on fatties and told them my tale of woe. Bob and another guy squeezed my tires and said they were way too hard, and in a way that left no doubt of their convictions. I wasn’t as sure but I promptly began letting out air and as Bob got ready to depart, he asked me if I had a pump in case I let out too much. I did.
I blogged a little bit about cornering back in August when I started learning how to pump a flat surface. Practicing pumping flat ground has helped me make some progress in my cornering ability, as you’ll see in the video of me below riding at Lebanon Hills a month ago or so.
Two of the how-to videos I linked to in that post also had segments about cornering technique, and the one called Hip Flexion by MTB coach Simon Lawton (free Fluidride videos here) recommends a slightly different technique for a berm turn vs a flatland or off-camber turn.
