Product Description

The Nimbus Hatchet Ultimate build is taking the amazing Hatchet and upgrading all the parts. We pulled no corners, the Ultimate build includes the behemoth 26" x 5.05" Snowshoe 2XL tire! This frame will hold a tire up to 26" x 5.05", 27.5" x 4", 29" x 3.0" and a 32" x 2.125.

  • Please Note: Do NOT use tire levers on B.A.D. rims! Nothing else offers the same combination of easy tubeless setup, stiffness, and jaw-dropping weight savings. They're utterly fat-tastic.

  • For all types of wheels, a hard strike on the rim is likely to result in rim damage. At the point of impact, an aluminum rim will dent, causing the rim to be a unsafe condition that requires a rim replacement. 

  •  The HED rim supplied with the Hatchet Ultimate comes supplied with a tube, you can setup to tubeless by purchasing a tubeless valve and sealant from your local bike shop. The rims do come with the Inflatobam parts from HED for tubeless setup. 

  •  Also please note that extreme force applied to the pedals can cause the frame/wheel to flex enough that the tire may rub the frame or your leg slightly, this is considered normal due to the large size of the tire depending on the psi in the tire.

    Note: Michigan Trail Tested, snowy conditions approved!
