Everything I read anywhere telss me that when riding I should spin at a high cadence. I'm trying, but I find that this doesn't work well for me. I am much more comfortable at a medium cadence with larger gears. Maybe not a true "gear masher" but I REALLY don't have fast legs. For me it's not just a matter of preference. When I try to spin my lungs end up working twice as hard for the same speed, and the same goes for my lactic acid build up in my legs. Pain happens much faster when spinning quickly than when I use more muscle and push the pedals a bit slower. Anyone else ride the same way? Or should I say have the same problem?
