In many instances I feel that it is possible to construct a retro bike and produce a 'fast' bike. This is probably a direct consequence of the attention to detail and the desire to pursue excellence. Maybe, the feeling of speed, is the end product of our efforts to minimise friction in mechanical movement and it manifests itself in reduced rolling resistance.
A colleague in a shop and I, built a Sabbath Silk Road for me.
It felt responsive, light and lightning fast. I loaned the bike to a regular customer for a Saturday club race, while we had his same bike in for an upgrade. He returned the bike with huge praise and uncontrolled enthusiasm. He did not win, but came close.
His assessment was that it was faster, smoother and 'tighter'
We agreed to strip and rebuild his month old Silk Road.
After using his rebuilt machine for the next race he enthused that it was the same as my bike and that this is what he meant by 'tighter'.
Responsive, Intuitive are words often used these day to describe characteristics of bikes. Such descriptions are to draw us in, to have us believe that the bike is 'alive' and can decide how to perform.
The truth is that we decide how a bike performs, we reap the reward of our efforts and integrity.
If a bike, old or new feels fast, it is fast. The most important distance that a bike can travel is the six inches between our ears.
