OK, I'll bite. What makes a bike faster besides the motor?

In my book, fit is faster, weight is faster, and component choice can be faster, gearing design and ratio can be faster. Is this the sort of thing that we are talking about?

Believe it or not, I can recall getting and thinking that the Quintanna Roo was too big for me and that I would never be able to push a 55 tooth big ring, especially considering the tight cog set...


But I was surprised. Was it the 650c wheels that made the difference or was it the 175 cranks or both? The bike is very light, when compared to anything else in my stable, now or in days gone bye.

Anyway, I should start a thread about what makes a bike faster. The one thing I do know for sure that it ain't me:-(
