Dylan Johnson is back with a follow up to the testing he and Josh did in the spring. The race season started with the two of them in the wind tunnel looking for Marginal Gains that could be used in the Lifetime Grand Prix and the other off-road races Dylan had on his calendar. Dylan reports back with his "on-course" experience and a look at how other racers are adopting some of the advantages he and Josh first discovered. Dylan also has questions for Josh on how some of the new "finds" and Silca products can be used at the pointy end of off-road racing. This is two Marginal Gainers sharing notes on another season of discovery and execution.
