Escape, enjoy bigger adventures, go further and explore harder. There are no more excuses.

The road goes on forever and the party never ends. When the Stigmata was resurrected in 2015, we fused a number of MTB standards and design features to create our spin on the modern CX bike. Something must have clicked, because, within months of launch, it raced to victory at the legendary Three Peaks and has continued to contend at elite cyclocross races around the world. Nowadays, the internally routed disc brakes, generous tire clearance, and thru-axle approach that made the Stigmata famous have become more of a norm, so we took a fresh look at which standards the riders of tomorrow wanted access to today. Threaded bottom brackets remain a perennial favorite across our entire line thanks to their proven robust, cost-effective, and compatible design. "If it ain't broke…" ...and it never is. Fender mounts add a bit of CYA and highlight the Stigmata's ever-widening scope of purpose. We added to that with three bottle cage mounts so that the frame can still hold at least one normal bottle even when running a front triangle bag. Deeper adventures and bigger tires, perhaps? The frame now clears up to a 45mm 700c or a 2.1" 650B tire. Marry the latter to our Force/X01 AXS mashup kit, and you've got yourself the kind of drop-bar singletrack and gravel rallycat we can all get onboard with. And, when it comes to good old-fashioned off-road etiquette, the Stigmata's had some coaching at the Highball school of stiffness, handling, and offroad feel. The carbon layup borrows knowledge gained from not just the Highball, but also Danny MacAskill's trials bike, to produce a ride so law-abiding you'd think HR had sent it on a compliance training course. Geometry plays a big part here, too, so we've made tweaks to improve handling for smaller riders and reduce toe overlap. The reworking of the 52/54cm frames means the Stigmata now comfortably suits riders from 5'3" and up. Meanwhile, different fork offsets (50mm for the 52-54cm sizes, and 45mm for the 56-61cm sizes) help ensure your little piggies don't go to market on the front wheel. Topped off with tidy details like 12mm front axle, flat mount brakes, and build-specific Reserve wheel packages, the Stigmata is designed to let you decide whatever the heck you want this category to be.

ARE YOU THIS RIDER? Do your friends ask if you intend to ride the chairlift when you invite them out for a 'few' park laps? Do your top routes frequently involve pushing up and down trails that aren't on any map? Do your favorite rides begin or end with headlamps, an ice chest, and great friends? Does your bike have to do everything well to get you there and back again? If you think you might be this rider, then Occam should be your bike. - Intended Use: Trail To Light Enduro LINKAGE UPDATE Occam uses a new two-part linkage design. Fewer pieces mean fewer interfaces, greater rigidity, and a lower chance of something working loose. Additionally, we have created a space in the axel and filled it with a handy 4 key multi-tool which is held securely in place with magnets. Always have the most-used tools close at hand for quick tweaks. INTERNAL CABLE ROUTING Occam has our latest, fully internal cable routing, using silicon plugs at the frame entry and exit points and clever conduits linking the front and rear triangle so your cables are fully protected. ASYMMETRICAL DESIGN Instead of using a less-efficient "shock tunnel", the Occam offsets the shock to the left side of the frame, allowing the right-side support to be more central and more efficiently deal with the suspension forces acting on the front triangle. This solution enables us to tune the stiffness of this high-stress area without adding unnecessary weight. THE ASYMMETRIC/OFFSET DESIGN OFFERS UNIQUE ADVANTAGES BEYOND STIFFNESS AND LOW WEIGHT. Avoiding an interrupted seat tube gives more space for dropper posts plus improves access to the shock controls. Additionally, the tidy design leaves room for a water bottle with easy left-side access.
