Gravity Basecamp 3.0 Mountain Bike Frame Set - 26" Wheel

The Gravity Basecamp 3.0 Mountain Bike Frame Set provides a solid foundation for anyone looking to build a custom 26-inch mountain bike without paying for a brand-name frame. The frame is constructed from 6061 aluminum with TIG-welded, hydroformed tubes, striking a balance between weight savings and structural rigidity. Its gloss black, unbranded finish keeps the aesthetic minimal and allows builders to personalize the look. The frame is designed exclusively for disc brakes and uses standard 135mm rear and 100mm front hub spacing, ensuring broad compatibility with readily available wheel sets.

What sets this frame set apart from a bare frame purchase is the inclusion of the SunTour XCT V3 suspension fork, which offers 100mm of travel along with preload adjustment and an advanced lockout mechanism. This fork alone can cost a significant portion of a budget build, so having it bundled adds real value. The kit also includes a standard 1 1/8" headset and a 31.8mm quick-release seat clamp, reducing the parts list for your build. You will still need to source a 27.2mm seat post, a 68mm English threaded bottom bracket, wheels, tires, drivetrain, brakes, handlebars, and stem to complete the bicycle. This frame set is best suited for trail and recreational off-road riding rather than aggressive downhill use.
