The Heyday! Advent is a machine made with adventure in mind. 26 x 4.6″ tires have no trouble rolling over loose terrain or tracking through overgrown paths. The aluminum frame blends durability and weight savings with stable geometry for roaming far and wide. And Heyday!'s versatility is unmatched: Alternator 2.0 dropouts allow for multiple drivetrain setups; cargo mounts let you load up for a day or a week; your wheel and tire options also include 27.5 fat and 29+. All this, paired with microSHIFT's trusty Advent wide-range 9-speed drivetrain, will remove “unrideable” from your vocabulary.
FEATURES:
On-Bike Storage: Carry more on your bike and less on your body. Our frames and forks feature mounts for extra bottles, camping gear, and ride accessories.
Alternator Dropouts: Tune your ride characteristics and switch to single speed with ease. Our swappable dropout plates allow for multiple drivetrain options.
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
Tire Clearance: 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
