“I finally got to ride my hightower today, broke my foot in June and haven’t been allowed/able to ride it since. Your BB is the smoothest one I’ve ever ridden, and I had 3 Enduro XD-15 and Wheels Manufacturing BBs. Nice job!”

“I’ve worked with these BBs since the first prototypes: silky smooth and outlast the rest”
