Front-end Compliance

Front-end Compliance

Synthesis Enduro Carbon front rims feature a bespoke rim profile, internal width, and carbon layup to provide lateral and vertical compliance characteristics where you need it most. Plow through rock gardens and root sections with increased directional control and reduced unwanted torsional feedback through the handlebars. And, a wider internal 31.5mm internal width allows for a large tire contact patch, resulting in more grip and confidence on the trail.

Rear-end Stability

Rear-end Stability

Synthesis Enduro Carbon rear rims feature a reinforced rim profile and carbon layup to provide additional stiffness and stability when loaded hard into corners, and also results in a robust wheel with superior impact resistance. A slimmed down internal width of 29.5mm allows for a fast-rolling tire profile relative to the front rim for pedaling efficiency.

New Ratchet Drive Hub

New Ratchet Drive Hub

Our entry point to Synthesis carbon wheels feature our new Ratchet Drive hubs, a low-drag hub design with improved engagement and durability in mind. From the factory, our Ratchet Drive hubs feature 36t ratchet rings resulting in 10° engagement, and all of our Ratchet Drive hubs can be upgraded with our 54t ratchet kit for an even quicker 6.6° engagement. A machined alloy hub shell and alloy axle help reduce system weight without sacrificing strength, while sealed cartridge bearings keep things rolling smoothly. Finally, a gloss-black anodization process with laser-etched Crankbrothers icons keep things classy. 

Quality Components

Quality Components

All Synthesis wheels are crafted with quality J-bend spokes from Sapim that are hand-selected for each wheel system's intended riding application - in the case of our Enduro Carbon wheel system, we choose Sapim's D-light model up front to allow for increased lateral compliance, while the slightly thicker Sapim Race spoke is selected for the rear wheel for added support and durability.
