What is the biggest obstacle to a fast ride: bearings or tyres, steep hills or air resistance? And what can you do to actually get faster with little effort? Here's the lowdown.

The enemies are invisible, but they attack the performance reserves of every cyclist: the tyres roll, the bearings rub, the air swirls. In many places on the bike, friction drains the energy from our legs and prevents us from simply going faster and faster. You know how it is: although your road bike is an incredibly smooth-running machine, there is a point for every rider at which nothing works any more. You look at the brakes, but nothing grinds. The physics of riding and our limited muscle power put us in our place. When drive power and driving resistance are in equilibrium, the speed stagnates. But how great are the individual resistances that prevent us from gliding even faster over the tarmac? And can these resistances be minimised?
