What Our Gearhead® Experts Are Saying:
"I’ve been running the 29 Boost version all season—it’s planted, responsive, and inspires confidence in rough terrain. The rim is super strong, and the CB Ratchet hub delivers smooth, fast engagement. It’s that perfect blend of alloy toughness with top-end performance feel."
For high-speed descents, enduro stages, and long park laps, we count on the Crankbrothers Synthesis Alloy 2.0 DH 29in Boost Wheel with CB Ratchet hub. It’s built to go fast, stay planted, and take hit after hit without flinching. From rim profile to hub mechanism, every component is optimized for stability, power transfer, and longevity.
The rear-specific build features a 29.5mm internal width to stabilize wider tires while improving edge control and traction. Its 6069 alloy construction is welded and shot-peened for class-leading durability, while a 32-spoke lacing pattern keeps it stout under pressure. With Boost 148mm spacing, the wheel adds stiffness without extra weight, and the Crankbrothers Ratchet hub offers 10° engagement with upgrade potential to 6.6°. The result? A bombproof wheel that punches well above its weight.
