At the heart of the Solix rear hub is a continuously-phased five-pawl freehub seamlessly integrating with a 121 tooth drive ring - offering 605 points of contact translating to an ultra-fine .59 engagement. Crafted from A2 tool steel using precision wire EDM, the pawls and drive rings are engineered for maximum durability. To bring resistance and freewheeling noise to a minimum, we've reduced the driving diameter, pawl rotation, and pawl spring pressure, and changed the FH seal layout. Matched hubshell bearing specs to evenly distribute loads, an updated bearing preload method to optimize performance and longevity, and freehub bearings with up to 233% higher capacity vs Torch The combination of endcap debris shields and new full-contact lip seals provide exceptional bearing protection in even the worst conditions Unique scalloped design of the hub flanges effectively distributes stress - improving strength while reducing weight Item Specifications Bearing Type Sealed Cartridge Cassette Body Type Shimano Micro Spline Color Black Defined Color Black Hub Drilling 28 Hub/Brake Compatibility Center-Lock Disc Rear Axle 12mm Thru x 148mm Skewer Included No Spoke Interface J-Bend Weight 227 Industry Nine Solix Classic Rear Hub Rear Hub UPC: 197769682544

From its scalloped spoke flange to its new seal design, the Solix Classic front hub represents the pinnacle of performance and longevity. Verses Torch front hubs, Solix employs matched bearing specs with up to 41% higher load capacity to evenly distribute loads, and an updated bearing preload method to ensure smooth performance and long service life. The combination of an endcap debris shield and our new full-contact lip seals provide exceptional bearing protection in even the worst conditions. Unique scalloped design of the hub flanges more effectively distributes stress than a simple round shape, improving strength while reducing weight Hub flange locations are perfectly placed to offer the best balance of bracing angle and spoke tension, ensuring a solid foundation for any custom wheel build Item Specifications Bearing Type Sealed Cartridge Color Black Defined Color Black Front Axle 15mm Thru x 110mm Hub Drilling 28 Hub/Brake Compatibility Center-Lock Disc Spoke Interface J-Bend Weight 120 Industry Nine Solix Classic Front Hub Front Hub UPC: 197769682384
