* Boostinator converts regular spacing wheels (15x100mm, 12x142mm) to Boost spacing (15x110mm, 12x148mm), so you can keep your good “old” wheels on your new Boost frame!* Wheels will need to be re-dished after installing the Boostinator* Please note that using the Boostinator may void the warranty of the wheel or hub* Rear DT kit fits all hubs with DT internals, but is not compatible with Center Lock hubs* For more compatibility questions, please see: http://www.wolftoothcomponents.com/collections/wheels-and-hubs/products/boostinator
