Not surprisingly 28/18 is also the gear ratios needed for 28mph and 18 mph same cadence.
rgds, sreten.
28 mph no wind, 18 mph into 10mph, both on the flat, drag = 28mph.
sreten you are off base. You can set up a situation with same cadence, same force, different gearing and different bike velocity that gives different power due to the velocity difference. That is what the 18/10 and 28/0 situation is. Not necessary to get more force at the pedals to get the higher velocity in the absence of the headwind. Therefore not necessary to have more force at the pedals to get the higher power generation. I have been paying attention to this ridiculous thread I inadvertently started. Have you?
