Mountain Bike’s First Tuned Wheel System
WHAT IS SYNTHESIS?
A tuned and optimized front and rear specific carbon wheel system that addresses the specific performance requirements and loads of mountain bike riding.
A compliant tuned front wheel to enhance control and handling characteristics through increased dampening while maintaining the wheels contact patch. It “turns.”
The front wheel is balanced with a stiff tuned rear wheel. This offers directional stability, anchoring and responsiveness in handling at speed. It “tracks.”
SYNTHESIS – SCHIERS & BOUWMEESTER
Jason Schiers has a long history in the bike industry and is a frontrunner in composite technology and application. He pioneered carbon rims for mountain bikes and started the era of strong and stiff carbon rims the market offers today.
Mello Bouwmeester, also having extensive experience composites, has more recently pioneered the new trend of wheel design that offers more compliance for better control and ride quality.
The synthesis of these two schools of thought is what Schiers and Bouwmeester bring to Crankbrothers. The new Synthesis carbon wheels offer the best of both worlds; an optimized wheel system with specific front and rear characteristics.
Synthesis11 Hub (Project 321 Internals)
Crankbrothers have exclusively partnered with US hub manufacturer Project 321.
Chosen for their precision and quality workmanship. 100% US made in Bend Oregon.
Innovate freehub design using magnets creating low drag and super fine pawl engagement.
6 Pawl, 144 Points of engagement (2.5°)
Patent pending ‘Quiet or Loud’ pawl design. Quiet pawls standard on Crankbrothers wheels. Loud offered as an aftermarket accessory.
Precision Japanese Bearings
Low drag magnetic pawls – By using magnets as a pull spring (opposed to mechanical or magnetic push springs) to move pawls into the drive ring, P321 are able to achieve less drag and less noise than other high speed ratchet mechanisms. The use of magnets in this configuration the pawl force against the drive ring is at its strongest when the pawl is fully engaged. As the pawl climbs the drive ring teeth during freewheeling the force (and friction) is reduced as the pawl magnets get farther away from the drive ring. This is the exact opposite of traditional mechanical push springs where the weakest point of the spring is at full engagement and the spring force gets stronger (creating more friction and drag) as the pawl is pushed up over the drive ring teeth during free wheeling.
Synthesis Standard Hub
3 Pawl, 21 Points of engagement (17°)
Crankbrothers standard 3 Pawl system hub offers time-tested durability and reliability with low maintenance grease based lubrication system, stainless steel pawl springs, and lightweight alloy freehub with XD or HG drivers.
