The dissident
A21
This is an archive page for the A21. Please refer to details and pricing of updated A21[M] here.
Utilitarian Fork - carry more
We've now updated our carbon fork to have 3-pack mounts on fork legs for extra water bottles or cargo cages. Front of fork crown is also drilled for light mount.
1x or 2x
The choice is yours - the A21 can handle them all.
Fully Internal Cable Routing - better shifting
Shifting degradation due to dirt and water ingress in your shift cable housing is one of the most frustrating things on a gravel bike. That's why we've painstakingly designed a 3D-cast titanium bottom bracket shell with integrated cable guides to make sure there is minimal exposure to the elements
Mudguards and Rear rack mounts
With a full array of mounting points for full fender and rear rack, when you're not doing a solo adventure in the middle of nowhere, the A21 slots in perfectly as the daily driver. Commute in comfort and style
Dropper post
Provision for internally routed dropper post: droppers are fun, you'll be glad to have one when you are under-biked down some serious single track, or stopped at a traffic light on your commute home with a foot down, dreaming about your next big adventure
More is not always better
Years of experience touring and bikepacking has made us sensitive to the number and location of all mounting points on the bike. Hours have been spent dialing in the precise location of mounting points to ensure maximum real estate for bags and other accessories. Case in point: did we forget to put in a bento-box style mount on the top tube you might ask? That was left out deliberately. It's neither elegant in function nor appearance, and they always interfere with frame bag straps. No mounts here increases your flexibility.
