Crank Brothers Synthesis V2 Alloy Enduro i9 Boost Wheel - 29in

Push hard and ride fast with the Synthesis Alloy 2.0 29in Enduro Wheel with i9 hubs—tuned for precision and power

What Our Gearhead® Experts Are Saying:

"I’ve been riding the Synthesis Alloy 2.0 Enduro wheels with the i9 1/1 hubs all season and they’re seriously confidence-inspiring. The tuned front and rear wheels feel completely dialed for great grip up front and precise tracking out back. And with the 4° engagement on the i9 hub, there’s no delay when I’m ready to punch out of corners or hammer up tech climbs."

We designed our dream enduro wheelset, then Crankbrothers made it real. The Synthesis Alloy 2.0 29in Enduro Wheel with i9 1/1 hubs brings together performance-specific wheel tuning and bombproof alloy construction to meet the demands of aggressive trail and enduro riders. Whether we’re sending bike park laps or wrestling through natural enduro stages, this wheelset delivers total control.

The tuned wheel system uses a compliant 31mm internal width front wheel with 28 spokes for more grip and flex, while the rear stiffens things up with a 29.5mm internal width, 32-spoke layout for max tracking and support under load. The 6069 aluminum rims are welded, shot-peened, and reinforced to shrug off impact and resist fatigue, and tubeless-ready design means less hassle and more ride time. The Industry Nine 1/1 hubs offer fast 4° engagement and a satisfying buzz, rounding out a wheelset that balances durability and performance beautifully.
