I am not expecting a direct comparison between the stationary bike and riding on the road. On the stationary I usually start on about 60 rpm and about 60 watts on level/ gear 4 which shows about 13 mph. About halfway when my legs are warned up i am doing about 70rpm and 14mph.
The main point is I am pedaling without stopping ir slowing down for 45 minutes.
Should I start going for an hour?
I want my legs in decent shape by the tome I drop enough weight to start putting miles on my bike. I read something about the weight limit on ny Roubaix and the big concern being the CF seat post. I’m not far away from a safe weight.
