Ajax
The urban ninja
Shhhh. What was that? Ajax moves through the city with stealth and speed, an urban ninja in matte black.
Wired bestowed Ajax with their "Gear of the Year" award and called it their “favorite urban velocipede we tested this year;” lofty praise from the oracles of innovation.
At the heart of this bike’s performance is its new-school drivetrain: an eight-speed Alfine internal hub and super-smooth belt drive that slices through the city like a shinobi in the night.
A favorite of tech-heads and entrepreneurs from Palo Alto to Brooklyn, Ajax delivers across the metrics that matter: performance, engineering, and — with many of the same high-end features as our Acme — it's also a great value. (We know that even urban ninjas need to complete their missions on a budget.) And like all of our street bikes, Ajax has hard mounts for racks, fenders, and a kickstand.
Technical Information
Gates CenterTrack
Next-generation Carbon Drive System. Unique, super-strong, carbon-reinforced polyurethane system that requires no lube and provides a nearly silent ride. CenterTrack is stronger, lighter, more compact, and better at shedding debris than the prior Gates systems.
Shimano Alfine 8-Speed Internally Geared Hub
Super-high quality with simple shifting and low maintenance providing a 307% gear range.
Spot Custom 7005 Aluminum
Proprietary, shaped, butted and tapered frame tubes designed for optimum strength, comfort, and durability. Lightweight aluminum tubing with precise tubing configurations for each frame size, results in a smooth and stable ride. Advanced performance styling of seat stays, top tube and down tube, in conjunction with finely tuned geometry deliver an astonishingly nimble ride in the urban environment.
Spot Custom Carbon Fork
Our newly designed all carbon fork rides smooth, yet is stronger and lighter that its predecessor. Steering is precise with the tapered carbon fiber steerer tube. Perhaps the highest performing street fork on the market.
Urban RocketSled Geometry
Cruise with your head up and pass on the left.
Dropout Compatibility
Newly designed Wagyū 2 Slider Dropouts allow belt-driven or chain-driven configurations, and painless wheel removal with no need to re-tension the belt.
Hydration Friendly
Water bottle mounts on down tube and seat tube.
Fender and Rack Mounts
Newly-designed frame and fork accommodate full fenders and racks, for urban versatility and utility.
