The Clutch v2 Hub is a traditional clutch-based coaster hub design that eliminates all of the problematic elements on ordinary hubs and only keeps the parts that work. A new, super-strong FULL 14mm axle, bearing configuration, and drag mechanism design stops the need for constant repairs. Equipped with external slack adjustment, which can be done with a 2.5mm hex key through a hub shell access hole (can be adjusted without removing the wheel), and an improved plastic hub guard spec. Same Clutch coaster hub you’ve come to love, but with a few upgrades. ###section### Product Specs HUB TYPE: Freecoaster AXLE: Female Bolts DRIVER: 9t SPOKE HOLES: 36h WEIGHT: 640g / 22.5oz
