OK... it has taken 120 miles (I have 520 miles logged on my bike)... but this spinning thing and how to use my gears... finally CLICKED!
Mind you, I mashed through about 400 miles on my bike... thus, I ended up wtih acute knee pain.
Also, I didn't have a clue about how to use my gears, what spinning, or cadence meant.
So, I slowed things down... backed off... kept at 10 MPH, just spinning my legs as fast as I could on my lowest gear.
Then, last weekend, I got up to 13 MPH average... but the spinning didn't click.
Finally... TONIGHT... I was averaging 16-18 MPH... and so fearful of hurting my knees... but I was spinning on the lowest gear... then when my butt would start to bounce in the seat I would go up a gear... amazingly enough, I wasn't mashing... but still spinning.
I also learned when to downshift to keep my spinning constant and to keep my cadence the same (I don't have a monitor but when by *feel*).
Moral of the story... don't mash on the pedals... start out right... learn how to spin... and you WILL get down the road FAST... but PAIN FREE!
Best of luck to everyone!
