BIKE AHEAD COMPOSITES impeller 26 "ac-26 biturbo Clincher MTB
Carbon wheelset with independent construction
The wheelset ac-26 biturbo is the further development of the known ac-26 biturbo. Particular attention was paid to the considerable decrease of the weight and maintaining high lateral stiffness. The result on the one of the best STW values (ratio stiffness / weight) available at MTB wheelsets. One reason for this is the special-spoke design of the wheels.
Instead thin with a variety spokes, the rim is connected by 6 hollow carbon spokes to the hub. This results in a higher rigidity and a simultaneous reduction in weight compared with the usual thin steel spokes, resulting in better acceleration and handling.
In the manufacture of the wheels no high-modulus fibers may be used. Thus, the wheels are resilient and absorb shocks better.
In addition, the rim is not damaged so quickly through the lower brittleness as edges.
The high strength of the carbon fibers, the rim hardly deform, so they do not have to be centered.
The rims and spokes are of the development and manufacture of composites Ahead itself.
The hubs of the wheels are from Acros and promise so that the same high quality of Acros products. There is thus achieved a long service life and very smooth running.
Quote BIKE MAGAZINE 05/13: results of this comparative test: "bike ahead" has the best 29er wheelset with the lowest weight, by far the best acceleration and the highest ever recorded in a 29er wheelset stiffness.
The company Ahead Composites develops and produces in Germany.
