Building Cadence.....

[sarahspins]

All other things being equal (grade, wind including whether or not you're drafting, road conditions, bike), then yes, there will be more force at a higher speed than a lower one - but all things are almost never equal, on a bicycle. That's why people spend thousands for power meters.

That's what I meant... all things being equal.. I realize that rarely happens, but still.. lol :P

But I do think that with increased fitness comes the ability to maintain a faster cadence... so it should come with time I don't think that 65-70 is dangerous at all.
