Frequently Asked Questions
MIPS is a low-friction layer inside the helmet, designed to reduce the rotational forces some impacts produce and to add protection in angled impacts, the most common kind in real-world cycling. Bell's 4Forty Air and XR MIPS use Mips Evolve, and the XR Spherical uses Bell's Spherical Technology powered by Mips.
Measure around your head with a soft tape about a finger-width above your eyebrows. Bell sizes are S 52–56 cm, M 55–59 cm and L 58–62 cm. If you land on an overlap, try both: the helmet should sit level, low on the forehead, and not move when you shake your head.
A mountain bike helmet covers more of the back of the head and has a peak for sun and branches, like the Bell 4Forty Air MIPS. A road helmet is lighter and has no peak, like the 260 g ABUS GameChanger 2.0 aero road helmet. The Bell XR range sits between the two for gravel riders.
Replace it after any crash hard enough to mark it, even if it looks fine. Bell say a helmet is built to protect you in one crash. Between rides, keep it out of a hot car, rinse the pads after sweaty rides and let it dry in the shade.
How to choose a bike helmet
• Trail and MTB helmets:How to choose a bike helmet
• Trail and MTB helmets: look for deeper rear coverage and a peak. The Bell 4Forty Air MIPS has a 3-position visor that lifts over goggles and weighs 360 g in medium. The ABUS CliffHanger MIPS adds lower edge protection and an adjustable peak (Small only).
• Road and gravel helmets: lighter, with more venting. The Bell XR MIPS Solid is 310 g in medium with a Deep Road fit, and the ABUS GameChanger 2.0 is an aero road helmet at 260 g in Small.
• One helmet for everything: the Bell XR Spherical is built for riders who mix road, gravel and singletrack. It weighs 285 g in medium.
• Kids full-face: the ABUS YouDrop FF Kids fits heads of 48–55 cm. The chinguard comes off for easy rides, and the peak is designed to detach in a fall.
MIPS and rotational protection
Bell's 4Forty Air and XR MIPS use Mips Evolve, a low-friction layer inside the helmet that adds protection in some angled impacts. The XR Spherical uses Bell's Spherical Technology powered by Mips, where the outer liner rotates around the inner liner in a crash. The CliffHanger also has a MIPS layer. All three Bell helmets close with a Fidlock magnetic buckle you can do up one-handed.
Fit and Australian riding
Measure around your head about a finger-width above the eyebrows. Bell sizes run S 52–56 cm, M 55–59 cm and L 58–62 cm; between sizes, try both. A helmet should sit level and low on the forehead and stay put when you shake your head. For a summer climb in Queensland heat, venting matters as much as weight: the XR MIPS runs large vents front to back. Riding Nerang, Derby or Stromlo, a trail helmet with rear coverage and a visor suits the terrain. Bell say to replace a helmet after any crash, even if you cannot see damage. Add bike lights for dawn rides.
