The First True MTB-Specific Free Coaster Hub just leveled up: the Sonar is now available in a 148x12mm Freeride/Trail Version.
Built with WETHEPEOPLE’s patented HYBRID System, the Sonar runs like a Cassette Hub but delivers full Free Coaster Functionality—with no extra parts. It’s Super Lightweight, Low-Maintenance, and features an Adjustable Slack System plus the MagnaDrive Magnetic Pawls, making it smoother and stronger than any clutch-style hub.
At 33% Lighter than most Free Coaster Hubs, the Sonar offers Zero Drag Performance and reduces Pedal Kickback on full-suspension bikes. After 4 Years of Testing with Rider Niklas Tilk, this hub is ready for Trail, Enduro, and Freeride MTB.
