Hi,

It does beg the question can you go faster by radically
changing the way you ride your bike ? I don't think so.

Whilst some waffle on about circles and the like, your nervous
system is a lot more adaptive and subtle than you might think.

For regular riding it will adapt to use your muscles in the most
efficient way possible, and a sure sign of the process is the side
effect where you gain conscious control of muscles you could not
control before, but that conscious control has no useful benefit
AFAICT, except perhaps for stretching / relaxing type stuff.

The only way of going faster on a bike overall is a lower,
more stretched, more aerodynamic, riding position.

Or :

Upgrading the engine is the obvious path for speed,
but unfortunately that takes the most hard work.

rgds, sreten.
