Heyday! Advent - Fat Bike

• 6066-T6 Aluminum Frame: Top-shelf, double and triple-butted, heat-treated 6066-T6 aluminum tubing is used throughout the frame. This 6000-series aluminum has better strength and fatigue characteristics than 6061 and 7000-series aluminums, allowing for a stronger and lighter overall frame. Additionally, the tubing is strategically shaped and formed for additional stiffness and strength optimization in key stress areas

• Heyday! geometry: Heyday! geometry works extremely well in all conditions and use cases, whether it's riding groomed singletrack at your local trail, exploring a coastline, or embarking across the wild frozen expanses of Alaska. We use the shortest chainstays possible with a headtube angle and fork offset that place the rider’s center of gravity farther back. This combination of front and rear center is key to getting a fat bike that is stable, steers well in loose conditions, and still feels nimble despite the massive wheels and tires. A low bottom bracket also keeps the rider’s center of gravity low and makes dabbing, dismounting, and remounting easier

• 26 x 4.6” Wheel & Tire Size: Heyday! rolls on 26 x 4.6" tires on 80 mm rims. This huge tire delivers massive traction, stability, and optimum floatation on soft surfaces such as ungroomed snow or loose sand

• Bearpaw Fork: This aluminum fork features a 150 x 15 mm thru-axle that boosts stiffness and improves steering precision. The fork also features our Three-Pack mounts for accessorizing with Anything Cages or water bottle cages

• Alternator Dropouts V1.0: Alternator Dropouts V1.0The Alternator dropout delivers incredible drivetrain versatility. Run singlespeed or geared, QR or thru-axle, freehub or Rohloff. Set the Alternator dropouts all the way forward for a shorter wheelbase that results in quick and nimble handling, or set back for more stability—the power is yours. See our Alternator page for more info
