BELL Z20 AERO MIPS

£209.99 With striking looks, effective straps, comfy pads and MIPS protection, the Bell Z20 Aero seems to have plenty going for it. But its weight of 281g is a touch high and, for such an aero-looking lid, it largely placed mid-table in the wind tunnel (it was good at 45km/h with a 0° yaw angle), consistently scoring below the Specialized and Giro, and often not much more wind-cheating than the £30 B’twin we tested as a road helmet example. All of which makes us question its worth, especially when venting is compromised by the 10 small channels and the financial outlay is over £200. zyrofisher.co.uk
