On the tarmac and in the crash test, it becomes clear which helmets offer the greatest safety reserves. Seven manufacturers, from Abus to Uvex, each sent an inexpensive and a top model at prices between 100 and 300 euros into the test race. One realisation up front: all the helmets are much better than the standard requires - but some offer a small safety advantage, regardless of price. Here: the Abus Game Changer 2.0 and the Abus Stormchaser ACE in a test duel.

Abus Game Changer 2.0: clever ventilation

All-round fit; without a rotation system (it is also available with mips), the sleek aero helmet offers slightly less protection than those with mips; among standard helmets, it achieves a high level; despite the closed shell, it cools excellently thanks to clever air routing; adjustment works well, only around the ears there is little room for manoeuvre; very light for an aero helmet; sunglasses can be safely parked at the front and rear.

Abus Stormchaser ACE: good protection even without mips

All-round fit, from a head circumference of 58 centimetres it presses slightly on the forehead and back of the head in size M; the helmet, which is available in 15 colour variants, is the lightest in the test; comparatively high protection even without Mips; the head always remains well cooled under the open shell; the Y-band cannot be adjusted, but the height adjustment works perfectly and a pigtail fits through well at the back; the reflective strips on the back are a safety plus in road traffic.
