Chromag Primer
The Chromag Primer is a Canadian-made all-mountain hardtail that blends raw strength with refined ride feel. Built from a custom-drawn 4130 chromoly tubeset, the Primer is known for its durability, vibration-dampening ride quality, and legendary steel resilience. Designed for aggressive riding, it features CNC machined dropouts and yoke, a tapered headtube, boost spacing, UDH compatibility, and a 12mm rear axle. The Primer isn't just tough—it’s tailored, with your choice of custom paint and an attention to craftsmanship that runs from the hand-assembled frame to the timeless head tube badge. Whether you're smashing big lines or setting out for a day-long adventure, the Primer is a modern hardtail built to last and designed to inspire.

Sizing Guide
The sizing chart is a great place to start when picking your next bike but everyone will fit a bike a bit differently. Your torso, arm, and leg lengths all play into what size of bike you may need. Plus, there's your own personal preference.
We always recommend swinging by the shop and taking the bike that you're looking for a spin to see how it feels. If you're unable to come by, looking at the geometry of your current bike and comparing it is a good place to start. If you have any further questions, our customer service team is there to help.
