Serk A21 “The Dissident” Titanium Gravel Frameset

Description

The Dissident – your magic carpet ride for when the pavement ends. Ultimate dependability in 3Al/2.5V titanium tubing and tyre clearance for up to 650b x 55mm, this is the go anywhere and do anything bike. Combined with a one-piece 3D-cast T47 BB shell, all cables and housing are neatly routed internally so you will never have to worry about dirt or water getting into your cables again (we know, we’ve been there). This is the bike for you if you constantly find yourself strapping stuff onto your bike and escaping the tyranny of the city.[split]

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.

The choice is yours – the A21 can handle them all.

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

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

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

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.

Geometry

Fun, sure-footed geometry: The soul of any bike is the geometry. Through years of experience of riding the backroads of Asia, we have tuned the geometry to represent what an all round adventure bike should feel like. 430mm of chainstay length makes sure that the rear end fits big volume tires and still remains snappy. The relatively steep seat angle ensures your weight is optimally centered between the two wheels and the lowered BB height makes you feel like you’re sitting IN the bike rather than ON it. Along with a slackened out head angle, the A21 will smooth out the roughest roads you can throw at it.
