Gravity Bullseye Monster Fat Bike Frame Kit 26 Inch

The Gravity Bullseye Monster Fat Bike Frame Kit provides the structural foundation for a custom 26-inch fat bike build. The frame is crafted from 6061 aluminum alloy, a material valued in cycling for its favorable strength-to-weight ratio and natural resistance to corrosion — an important quality given that fat bikes regularly encounter snow, sand, wet trails, and salt. Paired with a CrMo (chromoly) steel fork, the front end benefits from steel's inherent ability to dampen vibration and absorb trail chatter, offering a smoother ride on rough surfaces than a comparable aluminum fork would.

The kit ships with several ancillary components that simplify the build process: a headset, stem, seatpost, and seatpost clamp are all included, reducing the number of individual parts a builder needs to source and ensuring proper fitment with the frame. The rear triangle features 170mm symmetrical spacing, while the fork uses 135mm front spacing, so builders will need to select hub and wheel combinations that match these specific measurements. With clearance for 26 x 4.0-inch tires, the Bullseye Monster accommodates the wide rubber that gives fat bikes their distinctive traction on soft and unstable surfaces, making it a practical platform for snow riding, beach cruising, and trail exploration.
