Tuned Front and Rear Carbon Wheel System for enduro riding and racing. Front and rear specific wheels tuned and optimized to address the specific performance requirements and loads of mountain bike riding.

Compliant tuned front wheel improves handling and maximizes grip and control in turns. Wider inner rim width supports wider tire profile in front, increased volume and contact patch, and rounds tire profile to enhance turning.

Stiff tuned rear wheel supports peak loads and enhances stability and tracking at speed. Narrower inner rim width supports narrower tire profile in rear, improves rolling resistance, and sharpens tire edge for grip.

Snappy, buttery smooth, very strong!

So I've been around a while and have used a variety of wheels, both carbon and alloy, hubs of all price ranges, road, and mountain bike. I am really impressed with this wheelset. The idea of a ride tuned wheelset may sound like just another gimmick, but in practice it's actually quite nice to have a compliant front wheel, and a stiff rear wheel to track through challenging terrain.

The wheel-sets from Crank Brother's past where a bit too silly for my taste. I would have never purchased them on looks alone, but they also did not get good reviews. The new Synthesis wheels take the best of classic wheel design, new thinking on rim width, rim depth, and tire selection, and combine it to make an easily serviceable, strong yet compliant, great looking wheel set! Compared to other rims the profile is flatter, and less deep, aerodynamics be damned! This allows for longer spokes, which in turn adds compliance.

The set I purchased was built around what I believe to be one of the the best hubs, Project 321, with 6 magnetic pawls and 144 points of engagement. They make technical climbs a breeze, and I love how quiet they are!

When they arrived, I was impressed with them straight out of the box. Tubeless tape and valves where already installed, and tire mounting was a breeze! I set mine up with 2.8 front and 2.6 in the rear! Love them!
