After some shopping and research, I went with the Radix primarily for two reasons. First is that the sizing. I wanted a fitted helmet, not a ‘One Size fits most’. I figured getting a fitted helmet would be more comfortable and more secure. My head was right at 56 CM and the medium fits me well. The second reason was colors. Other models, like Fixture, had some real issues with grey and the visors not color matched to the helmet. The Radix had some great colors and I kept going back on forth. I went with the two-tone grey/lime. I really like the color. The top is a is a dark matte grey and the lime is more green than yellow, but is glossy in finish. Overall happy with the helmet. Good price, good ventilation, looks good, and good adjustability from the Roc-Loc.
