bike helmet

A simple approach to going aero which works well

Bontrager Velocis bike helmet tested and rated by our expert reviewer

Comfy, and offers top-line performance for a great price

Innovative features and great ventilation, but at a price

Reasonably light, comfortable helmet, with a solid retention system and replaceable X-Static padding – but a little bulky

Just lacks a little in looks, but still a really nice, well-priced lid

Not the lightest, but stylish design and a big tick for Rollsys

Unique design, well ventilated, but might not suit wide heads

We review Kask's Mojito bike helmet and make it one of our all-time favourites

A little heavy, but overall a solid long-tailed TT bike helmet with good venting and lots of aero R&D effort

Versatility, low weight and comfort – a serious option for long, hot races

Expensive and not the best for T1, but a high-quality TT helmet

Great value and packed with triathlon-friendly features, it also comes with Lazer's Rollsys dial adjustment for a comfy fit

Comfortable, adjustable, tunnel-proven and cool to ride in

Delivers a sleek-looking balance between aerodynamics and ventilation
