Synthesis E 11 Hydra Carbon Boost Wheelset

As carbon mountain bike wheels have grown in popularity, riders and manufacturers alike have learned that stiffer is not always better, as overly stiff wheels can negatively impact your bike's handling and even lead to bodily fatigue. Crank Brothers offers a creative solution with the Synthesis wheels, which use an independently tuned front and rear wheel to address the specific performance needs of enduro mountain biking. This consists of a more compliant front wheel that maximizes grip and control in turns, paired with a stiffer rear wheel that enhances stability and tracking at speed. Together they improve comfort and provide a boost of confidence in challenging terrain. This version is the flagship model, being laced up with Industry Nine's Hydra hubs that bring snappy pedal engagement and impressive reliability to your ride.
