A collaboration between HEL and Carder Tech—two brands that have chosen to work together rather than compete to produce the best components.
A stem is just that thing between the handlebars and the fork, right? So why spend too much money on it? But if you have a flimsy stem, your handlebars will wobble, and on top of that, some rides can be really tough. And this stem from HEL looks absolutely great, too—the craftsmanship is truly top-notch. Plus, there’s a choice of eight colors so you can match it with your brakes or HEL pedals.

Back in 1999, HEL Performance – also known as HEL (pronounced hell) began with a simple mission: to set a new benchmark for braking performance. HEL quickly evolved into a globally recognised, race-winning name in high-performance brake and clutch lines throughout the motorsport industry. From day one, there’s always been one clear vision: a refusal to compromise on quality or safety.
As of 2025, HEL is extremely proud to in-house manufacture a wide range of performance braking systems and advanced hydraulic components across three divisions: HEL Motorcycle, HEL Automotive, and now, HEL Mountain Bike. As a Made in Britain approved manufacturer, every HEL product is designed, developed, tested, and hand-assembled entirely in-house at our premises in Exeter, Devon.
After two years of behind-the-scenes development by a small 2-man team of passionate riders with deep roots in HEL’s motorsport division, HEL Mountain Bike soft-launched a new brake system to the market: the HEL Advocate.
June 2025 marked the official launch of HEL Mountain Bike - a new chapter forged from decades of braking expertise and true motorsport heritage, now reimagined for the trail. What comes next redefines the ride.
