Bontrager has designed its Circuit MIPS helmet as a jack-of-all-trades, whether it’s commuting, road or gravel racing.
It boasts a racy-looking shell where the composite outer acts as an external skeleton that allows for larger-sized vents without compromising strength.
This not only helps to keep weight down (280g in a small/51–57cm) but also aids with cooling.
The 15 vents with internal channelling worked well, so there was never an issue with overheating, even when I was working hard.
Alongside the neatly integrated inner MIPS safety system, I was impressed that the shell remained compact like a more traditional race helmet.
The shell also features Bontrager’s Blendr system on the top and rear that allows rattle-free mounting of a light and camera.
Helmet fit is adjusted with a neat looking Boa dial system that uses wires at the rear to secure tension. It’s incredibly simple to use as well as being lightweight, and it works a treat.
I also greatly appreciated the soft webbing side straps for the added comfort that they gave, and these are also easily adjusted with a flip and lock system.
The Circuit is a good all-rounder helmet and it comes with Bontrager’s free crash replacement in the first year for added peace of mind.
