HA, I did'nt have a fan but now I do and thats helps alot, the temp in the house is a comfortable 70 degrees, but I've since measured my cadence, after I warm up it's hovering around 90 with easy gears. But 2 yrs ago I used to be able to ride hard for an hour, complete a 20 mile course and my cadence was 100-105. But I guess that was then, and this is now
