Bumps and efficiency
Do bumpy road surfaces typically exact costs in riding efficiency?
While doing a loop that I've ridden dozens of times, I noticed that my speed had dropped almost two MPH from my norm on a section that had recently been chip sealed (as opposed to the baby's butt smooth pavement that existed previously). I didn't feel especially cooked (at least, no more than usual), there didn't seem to be any wind, and I was able to ramp the speed back up to normal after turning off the choppy surface, all of which led me to question whether it was indeed the bumpiness that was affecting me. Does anyone have any similar anecdotes? Any studies of this? Was I dreaming? I'm curious if it is more beneficial in a long ride/race where crappy roads are the norm to use 25mm tires vs. 23s. TIA, SYJ |
