Bontrager Quantum£44.99

Great value helmet

BikeRadar score4/5

Rather than being ‘cross-country’ or ‘trail’, the Quantum from Bontrager (Trek’s in-house components and clothing brand) is an all-rounder. Essentially, it’s a well-designed helmet to save your noggin from cracking if you kiss a tree. 

It’s a bit deeper than most pure cross-country designs, with a squarer back. Where the Quantum really scores is with its inherent stability. This thing feels like a socket on your head, and without feeling claustrophobic, as everything is simply just right and where you want it to be. The shape and retention device are so effective that there’s no need to yank hard on the nylon straps to keep it planted, even when bouncing down big trails.

Granted there will be some head shapes that don’t work. But those in the largest section of the bell curve will find the Quantum comfy like a favourite pair of slippers. 

Bontrager have taken design cues from Giro’s Xar to make this a one-stop shop of a helmet, something that can be sold to roadies, cross-country racers and epic all-mountain riders alike. That’s a pretty clever trick.
