In terms of weight and stiffness, the S2 is almost on a par with the much more expensive S5. In the wind tunnel, however, the influence of the standard wheels dominates, as they are not aerodynamic at all and are also quite heavy. The picture looks more positive after the comparative measurement with the Hadron wheels from Swiss Side, which save a whopping 14 watts. No other bike in the test benefited more from swapping the wheels in the wind tunnel. Logical conclusion: if the S2, then go for fast wheels. A weakness of the bike is also the disappointing equipment considering the price. There's nothing to be said against the new 105 gears, but simple brakes and cranks as well as the modest wheels seem a little meagre for € 2,700. The saddle of the S2 is comparatively hard.
