Kromo Dirt Jump Bike

We've been designing and building Jamis Dirt Jump bikes for decades. Now there's a new Kromo in our stable.

Kromo’s frame features a 44mm head tube to fit a variety of steerer tubes and headset types. It also offers fully external cable routing, integrated seatpost clamp, and horizontal dropouts.

Dirt jumpers and steel frames go together like tacos and Tuesdays. Our new Kromo sticks to this tried-and-true recipe by using 4130 steel as a frame material for an optimal blend of compliance and performance.

Manitou Circus Comp fork with 100mm travel, tapered steerer and 20mm axle takes care of suspension duties. ABS+ compression damping offers a big range of usable tuning to dial in stiffness.

Kromo includes only a rear brake, but a Novatec 6-bolt front hub and post mounts on the Manitou fork make it easy to add a front brake if necessary.

Samox chromoly 3-piece cranks with 28t ring can handle all kinds of abuse, from endless pump track laps and street sessions to those occasional not-so-perfect landings.

Tektro M275 hydraulic rear brake with a 160mm rotor helps dial in speed. Cable routing is 100% external to make brake swaps or maintenance a breeze.
