BBB ActionStem Suspension +10D 31.8 Bicycle Stem

BBB ActionStem Bicycle Stem (BHS-52)The BBB ActionStem is a revolutionary bicycle stem that introduces a new level of riding comfort thanks to its integrated shock absorption and vibration reduction system. This exceptional product has been designed for cyclists seeking a balance between performance and comfort, regardless of the surface they ride on. Thanks to its unique construction, the ActionStem effectively absorbs vibrations and shocks caused by uneven terrain, significantly reducing hand, wrist and arm fatigue during long rides.The ActionStem stands out with its adjustable damping level, made possible by the additional elastomers included, which allow the stem’s performance characteristics to be precisely tailored to individual preferences and riding conditions (up to 20 mm of damping). The varying angle depending on the stem length (from 0° for 60 mm to +3.5° for 100 mm) makes it possible to adopt an optimal riding position – from active and sporty to a more performance-oriented one. Made of high-quality 6061 T6 aluminium, the stem ensures excellent strength while maintaining a relatively low weight. Its versatility makes it an ideal choice for gravel enthusiasts, traditional road cyclists and people who commute to work by city bike every day.Key features:Integrated shock absorption and vibration reduction system for increased riding comfortAdditional elastomers for adjusting the damping level (up to 20 mm)Variable angle from 0° (60 mm) to +3.5° (100 mm) for different riding stylesMade of durable 6061 T6 aluminiumAvailable in five sizes: 60 mm (309 g), 70 mm (317 g), 80 mm (347 g), 90 mm (365 g), 100 mm (386 g)Designed for handlebars with a diameter of 31.8 mmDirect mounting on a steerer tube with a diameter of 28.6 mm (1 1/8")Compatible with BHS-91 Stemfix and BHS-92 GoFix mountsCertified for use with electric bicycles (E-Bike, EN 15194) and road bikes (EN 14781 / ISO 4210)Ideal for gravel, road and city bikesSignificantly reduces hand and wrist fatigue during long ridesSpecifications:Available lengths: 60 mm, 70 mm, 80 mm, 90 mm, 100 mmWeight: 309 g (60 mm), 317 g (70 mm), 347 g (80 mm), 365 g (90 mm), 386 g (100 mm)Angle: from 0° (60 mm) to +3.5° (100 mm), depending on the lengthMaterial: 6061 T6 aluminiumHandlebar diameter: 31.8 mmSteerer tube diameter: 28.6 mm (1 1/8")Damping: Up to 20 mm (adjustable using elastomers)Accessory compatibility: BHS-91 Stemfix, BHS-92 GoFixCertification: E-Bike (EN 15194), Road (EN 14781 / ISO 4210)
