Jon over at Can You Dig It dropped a review on an interesting cassette hub by a brand called Onyx racing. We’re not too familiar with Onyx, but they’re a company that, similar to Profile Racing, produces their products here in America and make some really high quality and dialed products. Jon has been testing out their Ultra cassette hub for quite a while that utilizes a Sprag Clutch system that we haven’t seen in BMX hubs before. It’s a really interesting design and he explains some of the pros and cons of this system. Check it out here — Onyx Racing Ultra Cassette Hub Review
