Synthesis Alloy 2.0 DH wheel combines tuned aluminum feel with I9 Boost performance
What Our Gearhead® Experts Are Saying:
"This Boost version of the Synthesis Alloy 2.0 DH wheel has been my go-to for downhill and park laps. The rear feels glued even on blown-out lines. The I9 hub offers near-instant engagement, and I haven’t touched a spoke all season. It’s everything I want from a gravity-ready alloy wheel—tough, responsive, and totally confidence-inspiring."
When every line matters and every hit counts, we ride with confidence on the Crankbrothers Synthesis Alloy 2.0 DH 29in Boost Wheel with Industry Nine hubs. Born from a collaboration with Commencal and battle-tested on the roughest tracks, this alloy wheel redefines what aluminum can do. It blends tailored ride feel with downhill-ready toughness designed not just to survive, but to thrive under pressure.
The Synthesis Alloy 2.0 DH is tuned with purpose. This rear wheel's 29.5mm inner width and 32-spoke layout ramp up stiffness and strength, allowing for confident cornering and reliable braking. Crankbrothers upgraded the rims to 6069 aluminum and added a shot-peened finish for maximum impact resistance and fatigue life. With a Boost-spaced Industry Nine 1/1 hub at the core, we get snappy 4° engagement that helps us power out of every corner and compressions with precision. This is a wheel we trust when the ride gets wild.
