in particolare mi ha colpito questo :
Another place where light wheels are claimed to have great advantage is in climbing. Though one may hear expressions such as "these wheels were worth 1-2 mph", etc. The formula for power suggests that 1 lb saved is worth 0.06 mph (0.1 km/h) on a 7% grade, and even a 4 lb saving is worth only 0.25 mph (0.4 km/h) for a light rider. So, where is the big savings in wheel weight reduction coming from? One argument is that there is no such improvement; that it is "placebo effect".
Cioè se ho capito bene con 1 libbra in meno sulle ruote (che sono ben 450gr.)
si guadagna solamente 0.1km/h in salita
SOLO ???
