  • "Before I found the Surface I’d tried a bunch of 29ers and although the benefits of the wheels were obvious often the bikes they were attached to felt a little too cross-country for my liking. I wanted a bike that I can race at the local midweek events, have a beer instead of washing it, then throw it in the back of my truck to go away for a weekend of epic, all-day rides with my buddies and never have to wonder if I have the right bike, no matter what trail we ride. I also want a bike built by Chris Dekerf because I know his heritage as a frame builder combined with the Chromag design philosophy and aesthetic."

  • Big wheels, all mountain

    We focused our carefully honed design ideas on the big wheel platform and the result is the Surface. Slack at the front and short at the back, ready to rip and beyond awesome. The Surface features a 44-millimetre headtube to accommodate tapered steerer forks and a 31.6 I.D. seattube for dropper post options.  It is made with custom drawn True Temper tubing and features our machined 'yokel' and asymmetrical chainstay arrangement for tire clearance.  This frame is made in limited productions so contact us for waitlist details.
