"The pad's knee cup is made from aluminum. Why? Dainese wanted to use a material that would slide over rough surfaces, allowing you to better absorb the impact instead of stopping dead when you hit the ground." Aluminium being a relatively soft material actually generates a lot of friction when hitting things like rock/rough surfaces, its quite "sticky". Probably worse than some plastics. If they wanted to do this "low friction sliding thing", steel might be a better choice. A lot of plastics are also fairly soft, so will also grip due to deformation, but unlike ally, some plastics are self lubricating

sweet! Thanks for the heads up, I'll keep an eye out for speedy Gonzales blasting past me on one of those furax things :D
