Remember the Silent Clutch rear hubs from Shimano? If you’re younger than 25, probably not. For the rest of us though, it was a rear hub that didn’t have the tell-tale ratcheting sound when you coasted. Law enforcement departments rejoiced. Nowadays, the Silent Clutch hub is limited to po po bikes as an Alivio-level hub. But if you miss the silent hub days, or want to build your own wannabe police bike, Chosen Smart Hubs have brought the silent hub back. Check out the video to see how it works. Well at least if you have working knowledge of rear hubs. The biggest advantage I see? No friction coasting. Woot!
