Bell 5Fifty Spherical Solid Mountain Bike Helmet in Black

Brand:Bell

Code:42571-001

Bell has clearly decided that the humble mountain bike helmet deserves a bit more attention. The 5Fifty Spherical isn't interested in simply sitting on your head and looking the part. It's packed with clever engineering, thoughtful details and some seriously impressive technology, all designed to make life on the trails more comfortable, more convenient and better protected. And yes, it looks pretty neat too.

At the heart of the 5Fifty is Bell's Spherical Technology powered by MIPS, a clever ball-and-socket construction designed to help manage rotational forces during certain impacts. But Bell hasn't stopped at protection. Motorsport-inspired Dual Flow ventilation keeps air moving through the helmet, the Float Race Fit system provides precise adjustment, and a Fidlock magnetic buckle makes fastening your helmet almost suspiciously easy. There's even dedicated storage for your sunglasses, a three-position visor and a removable camera or light mount. Bell has thought about the little things that make a big difference when you're out riding. Which is refreshing, because most of us have enough to think about when the trail starts pointing downhill.

Key Features

  • Spherical Technology Powered By MIPS – Innovative ball-and-socket helmet construction designed to help manage rotational forces during certain impacts

  • Fusion In-Mold Polycarbonate Shell – Durable, lightweight construction bonds the outer shell with the impact-absorbing liner for dependable protection

  • Dual Flow Ventilation – Motorsport-inspired airflow system helps draw cool air through the helmet and release warm air, keeping things comfortable when the effort ramps up

  • Float Race Fit System – Adjustable 360-degree retention system provides a precise, secure fit with a simple turn of the dial

  • Fidlock Magnetic Buckle – Clever magnetic fastening system makes securing and releasing the chin strap quick and straightforward, even with gloves on

  • Three-Position Adjustable Visor – Easily reposition the visor to manage sunlight or create space for goggles

  • Front & Rear Eyewear Storage – Integrated silicone grippers provide secure storage for your sunglasses when they're not on your face

  • Ionic+ Antimicrobial Comfort Padding – Specially treated interior padding helps control odour and maintain freshness during regular riding

  • Sweat Guide Technology – Clever padding design directs moisture away from your brow and eyewear. Because sweat in your eyes is rarely helpful when you're trying to spot the next root.

  • No-Twist Tri-Glides – Quick-adjust strap guides help keep helmet straps flat, properly positioned and free from unnecessary twisting

  • Removable Action Camera & Light Mount – Integrated mounting option allows compatible cameras or lights to be attached without complicated additional hardware

  • Motorsport-Inspired Diffuser – Aerodynamic rear diffuser helps encourage airflow through the helmet for improved cooling

  • Aggressive Trail Styling – Angular shell design gives the 5Fifty a distinctive, purposeful appearance

  • Secure Goggle Compatibility – Adjustable visor accommodates goggles for more demanding mountain bike riding

  • Comfort-Focused Construction – Carefully designed padding, ventilation and fit adjustment help maintain comfort during longer rides

  • Trail-Ready Protection – Built for demanding mountain biking with advanced impact management and practical coverage

  • Integrated Accessory Features – Thoughtful details make carrying eyewear and mounting compatible accessories simple

  • Performance-Oriented Design – Combines advanced protection, effective ventilation and precise fit adjustment for confident trail riding

The Bell 5Fifty Spherical is a helmet that's had some serious thought put into it. Every feature has a purpose, from the clever impact management system to the magnetic buckle you'll quickly wonder how you managed without. It's comfortable, brilliantly ventilated and packed with details that genuinely improve your riding experience. Bell has done a fantastic job of making the complicated engineering feel effortless. Now you can concentrate on riding your bike, which is rather the point of all this in the first place.

Buying guide

Standout Feature

Motorsport Inspired Protection

Bell's Spherical Technology is one of those clever ideas that makes you wonder why nobody thought of it sooner. Powered by MIPS, its ball-and-socket design allows the helmet's outer liner to move independently around the inner liner during certain impacts, helping redirect rotational forces. It's sophisticated engineering tucked neatly inside a helmet that looks ready for business. Add the aggressive styling and you get something that looks every bit as capable as the technology underneath it.

The motorsport-inspired Dual Flow ventilation is another particularly clever touch, drawing cool air through the helmet to help regulate temperature. Bell has also included a Float Race Fit system, magnetic Fidlock buckle and dedicated eyewear storage, because apparently simply protecting your head wasn't enough. The result is a helmet that feels properly considered, right down to the smallest details. All you need to worry about now is choosing the right line down the trail.
