Typically, wheelsets come in a matching pair, and while it's common for riders to run with slightly lower air pressure in the front, most still run the same wheel in the front and back.

Crankbrothers took a different path when designing their Synthesis Carbon Wheelset—recognizing the different rolls the front and rear wheel play. More compliance in the front adds to the wheel's ability to stick to tight lines and hold great traction. At the same time, added stiffness in the rear gives you the confidence to power through big impacts and hold onto tight turns.

Crankbrothers went back and forth with countless designs and prototypes until they reached an ideal combo that offers just the right balance.

The Synthesis front wheel features a reduced number of spokes, lighter gauge spokes, and lower spoke tension. The front rim is also more lightweight and slightly wider than the rear. This design gives you a supple, compliant ride that tracks like a laser.

Crankbrothers then pairs it with a rear wheel with a higher spoke count, higher tension, and a narrower rim. With the added stiffness and different rim design, you get a sharp tire profile that's ideal for cornering. The rim design also features thicker flanges, explicitly built to handle high impacts and increase stability.

They've taken durability and strength to the next level in both rims, too. Backed with extensive research on how carbon rims fail and how to manage and avoid catastrophic failures, the rims have ultra-thick carbon sections that can't be matched in strength by traditional, thin-wall, tubular rims.

Crafted with special high-impact resins and tailored to disperse impacts, the rims have been designed with similar specifications to the carbon protection found in F-1 race cars. Crankbrothers backs up their build quality with a lifetime warranty on the carbon rims, too. 

Crankbrothers Synthesis Carbon Wheelset is truly tuned and optimized to a level that few others offer right out of the box. If you're looking for an enduro or racing wheelset that's purpose-built for the high performance requirements and loads of agressive mountain bike riding - these are your wheels!

    Everything I expected

    This is my first set of carbon wheels and they've meet all my expectations. The compliant front wheel tracks and holds a line as if you were riding hero dirt at all times. That paired with the engagement of the I9 Hydra and stiffer rear makes this wheelset pop and accelerate on demand.
