Lazer Z1–Lotto-Soudol
Thanks to Andre Greipel (four stage wins in this year’s Tour), we’ve seen the Fast version (with glued-on Aeroshell covering the vents) of Lazer’s Z1 quite a bit. The standard Z1 ($279*), shown here, can be converted to look like The Gorilla’s helmet with optional clip on Aeroshell ($20*) when some weather protection or (claimed) enhanced aerodynamics is needed. You can also use without for a bit less weight and magnitudes more ventilation.
*Pricing updated to reflect Canadian MSRP
Check out the Z1, Z1 Fast, and Cosmo (women’s specific version) at your local Lazer dealer.
