The Grindstone Compound is a progressive training environment designed for the aspiring MX athlete.

Unlike traditional “training facilities”, Grindstone is a launchpad – a central location in the heart of Southern California that provides riders with essential needs and services to focus on their riding career. On the main floor, each member has their own personal work bay for bike maintenance with access to a community wash station. The upper level offers living and recreation space to unwind, and outside, head out the shop doors straight for La Cresta mountain bike trails for the imfamous  “La Cresta Road Loop”. . Grindstone is located within an hour of SoCal’s best tracks including Milestone MX, Pala, Cahuilla Creek,  Perris MX, Comp Edge and Glen Helen.
