Additional Features

High-Modulus Carbon Fiber Frame

This material offers the best blend of stiffness, vibration damping, durability, and weight savings

Heyday! Geometry

Heyday!'s 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

Kingpin Deluxe Fork

Featuring full-carbon construction, the Kingpin Deluxe Fork is lightweight and durable, with an amazing array of accessory mounts to help you make the most of your Mukluk: Two sets of Three-Pack mounts on each fork leg for water bottles or Anything Cages / Lowrider rack mounts work with our Down Under front rack for a traditional touring setup / Internal dynamo hub wire routing keeps the front end looking clean

Alternator Dropouts V2.0

Heyday! Carbon is spec'd with a two-position fixed plate. The first of the two openings allows room for a 4.7" tire on a 70 mm rim and keeps chainstay length to 432 mm. The second position sets the wheel farther back, giving you options for larger rim and tire combinations. Adjustable dropout plates are available separately for single speed setups or finer adjustments

Front Wheel and Tire Options

The fork included with this frame works with the following wheel and tire combinations: 26 x 3.8-5.0" on up to a 100mm rim / 27.5 x 3.0-4.0" on an 80mm rim / 29 x 2.3-3.0" on a 50mm rim
