Last week, I wrote a story breaking down the aerodynamic implications of the various available configurations of carrying water bottles on your bike. The story was primarily aimed at road racing cyclists, with the tested configurations covering one, two or three bottles, aero bottles, and a mixture of where you could put them on most bikes.
But with Unbound Gravel set to light up our social media feeds over the coming week, we also wanted to run some tests on carrying a hydration pack to see whether there were any gains to be found.
