Went out with a bunch of family to Sherwood Pines. I didn't die! It was fun! The Proflex worked almost perfectly on its first proper outing. One rear V-brake jettisoned a brake pad cartridge, but my brother had some spare crap brake pads in the car. Going to blame the 30 year old retaining pin for that one; I think I'll just replace them all with single-piece ones.
