I’ve been using ERG mode on my Kickr for about eight months. I started with 50x14 gearing, but about a month ago realized the I was having trouble maintaining 80rpm on flats and steep gradients (above 10%) were pushing my watts above 325 just to keep the cranks turning. Not sure if this was due to automatic power increases by Zwift as I became more fit? I’ve recently upshifted to 50x15 and seem to have found a happy medium.
That being said, I tried Alpe du Zwift for the first time yesterday and really struggled on the early sections. I shifted up to 50x17 and was able to handle the climb. I averaged around 260w versus the 340+ in the harder gear. Is this cheating?
I’m 51 and a large rider - 6’5" @ 225lbs. I want to work hard to continue to improve but don’t want to injure myself by pushing super heavy gears at low rpm. Would appreciate any advice. Thanks
