My bike specs:

Cassette: 2010 Shimano 105 HG5600 10 Speed Cassette 12-25T
Chain: 2010 Shimano CN5600 HG 10 Speed
59cm frame for 6'0" rider

What do other people have as average and top speed? Is it conditioning, components, or both?
I would like to average over 30mph on flats, and be able to top out higher than that.
From what I read, the number of teeth in the chain ring is what will increase top speed? And that the crank arm length also, to a smaller extent?
Thanks.
Yes, no

Can only be done by a few world class cyclists for more than a few minutes.
