The latest addition to the Storck fleet, the new Adrenalin 1.7, is the result of a deep dive into the engineering box. The frame is manufactured using the V.V.C. process (vacuum-assisted process to optimise the resin content) and, as a supported single-pivot frame, dispenses with the lower bearing in the seat stay and instead works with a flexing flattening of the tube. This is intended to ensure high rigidity on the one hand and low weight on the other. With 81 Nm/° (STW 33.96), the frame is also promptly at the top of the field in terms of stiffness.
On the trail, the Storck surprises with the most sensitive suspension. The rear suspension and fork work together perfectly to filter even the smallest bumps out of the ground, making the rear end feel like it has significantly more than the measured 96 millimetres of travel on descents. However, the shock tends to compress slightly under powerful acceleration. Downhill handling suffers due to the narrow handlebar and the combination of a high bottom bracket, steep steering angle and short head tube. The equipment of the Adrenalin is solid, but contributes to the highest overall weight of the test group.
CONCLUSIONThe stiff Adrenalin 1.7 impresses with the most sensitive suspension in the test, but loses points in the criteria "downhill" and "weight".
