However, thought the power transfer might be more efficient, the weight reduced, the aerodynamics might be better, tyres thinner, less rolling resistance.
All these things are real, but ….
…as with ‘lighter wheels’, as with a ‘carbon frame’, as with ‘deep section rims’, as with ‘energy drink’, as with ‘race tyres’, as with a ‘super light bike’, the basic issue of moving you still remains.
The reason I am so sceptical of all the ‘Oooh, I got some lighter wheels and now my bike flies like the wind’ posts is because it’s just not true.
People think that losing a few hundred grammes will make their bike soooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo much faster, and it is demonstrably cobblers.
