The Crankbrothers Synthesis E 11 - Project 321 Hub Black 27.5" Shimano Boost Pair exemplifies advanced mountain biking engineering, purpose-built for enduro riding and racing. This high-performance wheelset features a meticulously tuned design that addresses the specific demands of rigorous mountain terrain, delivering a harmonious blend of durability, control, and speed. Each wheel is engineered with distinct characteristics: the front wheel enhances traction and handling, while the rear wheel prioritises stiffness and power transfer, ensuring an optimised riding experience.
Constructed with premium Sapim spokes and equipped with the innovative Project 321 hub, these wheels provide quiet, reliable engagement through magnetic pawls, facilitating smooth and responsive pedalling. The front wheel’s wider inner rim width supports a larger tyre volume and contact patch, improving cornering grip and responsiveness. Conversely, the rear wheel’s narrower rim width reduces rolling resistance and sharpens tyre edge grip, enhancing stability and efficiency at high speeds. This combination is ideal for riders seeking a precise balance of performance attributes in a durable package.
Designed for mountain biking enthusiasts who demand reliability and performance, this wheelset is backed by a lifetime rim warranty, underscoring its quality and long-term resilience. Explore more from the mountain biking collection to complement your setup with components that meet professional standards.
Is this wheelset compatible with all Shimano Boost setups?
Yes, the Crankbrothers Synthesis E 11 wheels are specifically engineered for Shimano Boost hubs, ensuring seamless compatibility and optimal performance within this standard.
What advantages do different rim widths front and rear provide?
The wider front rim accommodates a larger tyre profile, enhancing grip and handling in corners, while the narrower rear rim reduces rolling resistance and sharpens tyre edge grip, improving efficiency and stability during high-speed riding.
