Thanks for all the advice so far. Our team weight is 320, exclusive of the bike. And, yes, as steve53mg surmises, we will be on the conservative side, especially in our early days as a team. We enjoy biking not for the speed but for the experience, the scenery, and the beer at the end of the ride. Our goal is to live to ride another day.
Question for steve53mg: Do you recommend purchase of an Arai brake because A) they are the only drag brake made by anyone, anywhere, or B) it is your preference over any other manufacturer?
Please keep the feedback coming!
