The BOX Three Pro cassette disc hub is a hand built to a double wall rim using stiff stainless steel spokes. With this kit you will be able to adapt a Hydraulic brake to your 29" single speed bike. It comes with everything you need including the Box Three Pro disc cassette rear hub, Stainless steel spokes, and SE bikes J32S double wall rim already bolted up ready to go. The hub has 120 points of engagement to give faster power to the wheels. It comes in the correct single speed frame rear end width at 110mm. The hub has sealed bearings all around to keep your wheels rolling smooth. The American made Stacked Hydro power brake adapter is perfectly made to add a disc brake to a V-brake 29" bike. The correct Shimano adapter is centered and bolted up to the caliper evenly for superior stopping power. The hydraulic brake is bled and the cable is cut for your selection of height bars (email us after you place your order with your order number in the subject line and state how tall your bars are.

Stacked Word about Hydro power adapter

Do you need a Hydraulic Disc brake on your stock bike? The Stacked BMX Hydro Power Hydraulic 160mm Disc Brake adapter allows you to put a disc brake on any bike with a 3/8" horizontal dropout. This fits most bikes on the market including brands like Throne, SE bikes, Haro, Crew, Mafia, Hyper and many more. Simply slide this on the axle in-between the hub & frame with the block in the dropout slot to take advantage of its stopping power. You can bolt any 78mm mechanical or hydraulic brake to the mount and wallah you now how disc brakes. Make sure you use a disc compatible hub, we do not recommend a fixed/disc conversion (there is not a quick fix to mount a disc on a no disc hub). Most inexpensive disc compatible wheel is the mag version, the most trust worthy is the Profile Racing Elite with disc hub. Pick it up and have a wheelie good time.
