Bell Sixer Mountain Bike Helmet with MIPS - Solid Matte Black

Season:SP26

Brand:Bell

Code:40119-255

The Bell Sixer MIPS Mountain Bike Helmet is a premium trail and enduro MTB helmet built for riders tackling everything from technical rock gardens and steep descents to fast-flowing singletrack and long backcountry adventures. Combining advanced protection, exceptional ventilation, and all-day comfort, the Sixer MIPS is designed for serious mountain bikers who demand performance and reliability on every ride.

At the heart of the helmet is the MIPS Evolve rotational impact protection system, engineered to reduce rotational forces during certain angled impacts. By integrating the MIPS slip-plane directly into the helmet’s retention system, Bell delivers a sleeker, lighter design with improved ventilation and a closer, more comfortable fit for aggressive trail riding.

The Float Fit system provides a secure and fully adjustable fit with three-way customisation including height, pad width, and tension, allowing riders to fine-tune the helmet for maximum comfort and stability on rough terrain. Combined with the Sweat Guide padding system, moisture is channelled away from the brow and eyewear to keep sweat out of your eyes during long climbs and demanding descents.

For superior cooling, the Sixer features advanced ventilation with internal air channels that actively draw cool air through the helmet while pushing warm air out, helping regulate temperature even on intense rides or hot summer days.

Built with a durable full hard-shell construction and variable-density EPS foam liner, the helmet effectively manages impact energy while maintaining lightweight comfort and durability for demanding trail conditions.

Trail-focused features include a 4-position adjustable visor for sun protection and easy goggle storage, plus a rear goggle strap grip to keep your goggles securely in place during aggressive riding. The helmet is also goggle compatible and includes an integrated breakaway camera/light mount, allowing you to attach action cameras or lights without the need for zip ties or tape.

Additional premium details such as quick-adjust strap fasteners, quick-drying antimicrobial padding, and a secure ergonomic fit system make the Bell Sixer MIPS one of the most versatile and comfortable trail mountain bike helmets available for enduro, trail riding, and all-mountain adventures.

Whether you're tackling technical descents, fast alpine trails, or epic backcountry rides, the Bell Sixer MIPS MTB Helmet delivers the protection, ventilation, and performance modern mountain bikers demand.

Sizing Information

Helmet Size Guide

How to measure your size – Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide. Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit. SOME MIPS® LOW-FRICTION LAYERS, ALONG WITH OTHER PARTS OF A HELMET, MIGHT CAUSE LACERATIONS TO THE WEARER’S HEAD/FACE IN SOME ACCIDENTS. THIS MIGHT OCCUR DUE TO THE HIGH PRESSURE ON THE SCALP FROM THE IMPACT OR AS A BY-PRODUCT OF THE LOW-FRICTION LAYER’S MOVEMENT IN CERTAIN ANGLED IMPACTS TO HELP REDUCE THE ROTATIONAL ENERGIES TO THE HEAD.
