Mechanical disc brakes, a frustrated review

I suppose I can say I was a pioneer of disc brakes on road bikes, having bought the first one in December 2009. Ok, it was sold as a cyclocross bike, but the knobbly tyres got immediately replaced with slicks, so it was in practice a road bike. It came with some dreadful Shimano BR…

Calculations of speed and power
