Track season is upon us here and for the next 4 weeks the guys will be riding 74 gear inches to develop their spin before they move up into the low 80's... considering here that the track is smooth and there are no hills and no wind that one has to deal with.

In the old days people started training by doing 1000 miles on a 74-76 inch gear and this is what was often used on the open road to knock down sub hour 40's... you have to spin that at 110 rpm or more for a full hour to knock this down and have to deal with wind and grades.
