KROSS ESKER FL

The KROSS Esker Flatbar is a gravel bike for those who appreciate speed and performance but prefer the comfort of flat handlebars and a more upright riding position. Equipped with a second-generation GEN2 aluminum frame and a carbon fork, it offers strength and comfort at a low weight. The SHIMANO Cues 1×10 drivetrain and hydraulic disc brakes give you complete control on any trail—whether on fast stretches of asphalt or challenging gravel roads. The KROSS Esker Flatbar is the perfect choice for anyone looking for a versatile bike for the city, gravel roads, or long weekend trips

Cross bike in a new edition – GEN2

The first-generation Esker impressed both experienced cyclocross riders and newcomers seeking a versatile and reliable companion for exploring new routes and adventures. The bar was set high. The new second-generation Esker – GEN2 – is an exceptional choice for those who want to unlock the full potential of gravel bikes and enjoy riding on diverse, even challenging, terrain.

The new GEN2 aluminum frame, made from break-resistant and ultra-lightweight performance aluminum, features a multitude of mounting points for bags, racks, fenders, and more. There’s also a dedicated spot for mounting a kickstand. The lightweight and stiff carbon fork, developed by KROSS, features internal brake cable routing and is compatible with 30mm travel suspension forks.

The lowered center of gravity and increased wheelbase improve the bike’s handling, both with and without luggage. The new GEN2 frame also means a lower crossover height, making the bike more appealing to a wider range of gravel enthusiasts.

Highlights:

  • POWDER-COATED: Coating is achieved by applying electrified powder coating particles to aluminum, which requires thermal treatment. After baking, the coating surface forms a perfectly smooth layer that is extremely resistant to mechanical damage
  • RHS SYSTEM: To protect the frames as effectively as possible, a system of replaceable hooks has been developed, which can be easily and quickly replaced in case of damage. To minimize the possibility of frame damage, a thread is applied to the hook or a special nut.
  • FLAT MOUNT: A new standard for brake mounting that allows for greater integration of the brake caliper into the frame, thereby increasing stiffness, reducing weight and improving aerodynamics, which, combined with the lower weight, has a positive effect on riding dynamics.
  • INTERNAL CABLE ROUTE: Internal cable routing extends the lifespan of the cables, as they are protected from mud, sand, and rain along with the braiding. This saves valuable grams and gives the bike a clean, sporty feel.
  • T-HEAD TUBE: Tapered head tube with a variable cross-section from 1 1/8″ at the top to 1.5″ at the bottom. The larger diameter at the bottom provides greater strength and stiffness, resulting in precise steering.

As with all high-quality bicycles, pedals are not included. These bicycles are typically ridden with a clipless pedal system, which the customer selects and purchases according to their needs. Of course, you can also ride with standard platform pedals.
