I've ridden tire/wet dirt surface combos that felt like fly paper. I've felt like I had no strength. I've felt strong only to get my doors blown off by a rider one wouldn't categorize as strong or fast. I've felt so fast that I thought my tires would burst into flames. have an off day? don't sweat it. cuz on another day, you'll feel the opposite. like days where time goes slowly & other days fly by
