Lighter is not always better. I used the B6 rear inner titanium hinge pins from Revolution Design (#RDRP0282-INR) as front inner hinge pins for my B74, as they are of the exact same dimensions. It worked for two races, but during my last training, both pins bent. First on the left an a few runs later on the right side. Maybe steel pins would also have been bent, because i hit the timber very hard several times, but to destroy both sides within a few packs is at least ominous.
