Synthesis V2 Alloy Enduro CB Ratchet Boost Wheel - 29in

What Our Gearhead® Experts Are Saying:

"I’ve run the Synthesis Alloy 2.0 29in Enduro wheels through chunky rock gardens and steep chutes without a hiccup. The front’s compliance lets me hold lines through tech while the rear’s stiffness tracks at speed. The CB Ratchet hub’s 10° engagement hits that sweet spot between power transfer and durability. These wheels are dialed for big-mountain abuse."

We crave terrain that challenges both rider and machine. That’s where the Synthesis Alloy 2.0 29in Enduro Wheel with CB Ratchet from Crankbrothers shines. Developed with Commencal’s performance obsession in mind, these alloy wheels are tuned for aggressive riding, pairing a compliant front wheel that boosts grip and handling with a stiff rear that delivers tracking precision and stability under peak loads.

Built from refined 6069 aluminum, the rims are shot-peened for enhanced fatigue resistance and impact strength. Reinforced sidewalls and a new rim profile reduce pinch flats and shrug off high-speed hits. Each wheel is tailored—front and rear specific widths, spoke counts, and tensions—to create the ideal enduro setup. And with the CB Ratchet hub’s 10° engagement, power is always on tap when the trail demands it.
