What Our Gearhead(R) Experts Are Saying: "I was blown away by how well this wheel balances precision and comfort. The tuned front/rear stiffness really works-plush up front, stiff and snappy in back. It's legit for big enduro days." Confidence on demanding descents starts with a wheel that rides smart, and the Crank Brothers Synthesis Enduro Boost Wheel delivers just that. It brings a tuned, asymmetric design that strategically blends compliance and stiffness-softening the chatter up front and locking in control at the rear. This wheel is built for serious riders charging big mountain terrain, bike park lines, and enduro stages. The Synthesis Enduro pairs a compliant front rim for tracking and traction with a stiffer rear rim to improve power transfer and durability under hard hits. Boost spacing improves stiffness and clearance, while the high-flange hub shell enhances strength without excess weight. Whether you're threading technical rock gardens or dropping into loamy chutes, this wheel feels composed, precise, and built to go hard.
