BBB DownForce 31.8mm Stem: Precision Control for Every Ride
Unlock your perfect ride with the BBB DownForce 31.8mm stem. This versatile, 3D-forged aluminum stem offers a +/- 17-degree angle, letting you choose between an aggressive, aerodynamic position or a comfortable, upright stance. Engineered for Road, Gravel, and MTB, its rigid one-piece construction ensures precise steering and efficient power transfer. Durable, stylish, and EN certified for E-bikes, the DownForce is your key to enhanced control and comfort on any terrain.
Master Your Cockpit, Master Your Terrain
The BBB DownForce is more than just a component; it´s the command center of your bicycle. Designed for the discerning cyclist who demands both performance and adaptability, this stem provides the ultimate solution for dialing in your bike fit. The key lies in its reversible +/- 17-degree design. For the competitive Road Cycling enthusiast or criterium racer, mount it for a steep negative drop to achieve a low, aggressive, and aerodynamic profile that cuts through the wind. For epic days of Gravel cycling or navigating technical singletrack, simply flip the stem for a positive rise, bringing your handlebars up for a more relaxed, upright posture that reduces strain on your back and neck during long hours in the saddle.
Uncompromising Strength and Performance
Engineered from a single piece of high-strength, 3D-forged Aluminum, the DownForce boasts an exceptionally stiff and robust structure. This one-piece design eliminates weak points, flex, and creaks often associated with lesser stems. The result is a direct and unfiltered connection between your handlebars and your front wheel. Every input you make is translated into immediate, razor-sharp steering response, giving you the confidence to carve corners with precision and navigate challenging lines with absolute control. This impressive rigidity also ensures maximum power transfer, meaning the energy you exert during sprints or steep climbs goes directly into forward momentum, not into flexing your components.
Finished with a sleek, black-on-black design and secured with durable stainless steel bolts, the DownForce stem not only performs at the highest level but also adds a touch of professional style to any bike. Its reliability is further underscored by its certification for E-bike use (EN 15194), proving it can withstand the increased forces and demands of modern electric-assist bicycles.
