I noticed that when I really give it hell after stopping or riding slow (I do that all the time on commute), I have to shift two gears at a time in the lower gears, to keep up with my acceleration. I then asked myself whether there's
any better way for the shifting to keep up with my acceleration. The shifting process itself goes very smooth and I can time it very well in my opinion.
Also, how do real bike racers do it? The reason I ask is that I hardly believe that racers always loose time with shifting over several gears before the next "thrust". Or does that not cause lots of time loss?
Do racing bikes have special gear ratios for optimizing speed of the shifting process?
I only cycle as a commuter (just 3.6km), but I probably behave somewhat like a racer (regarding speed) as well on that short route.
