• aero considerations(both frame and tyres)
• bb area stiffness
• geometry
• anything else I haven't thought of, or thought to mention

And I am surprised at times how many people would insist that the sort of speed improvement you saw from one bike to the other, isn't likely or even possible.


Obviously the most important aspect of speed is the motor(i.e. rider), but the part all of the other components play is very interesting to me and I am always surprised when people seem reluctant to want to explore this further.


So thank you for your posts.
