Gravity: The fun part of mountain biking


Guerrilla Gravity is a mountain bike manufacturing company. We believe businesses exist to serve their communities, so we've made it our mission is to make mountain biking more awesome. What does that entail? Improving trail access, increasing ridership, and of course making badass mountain bikes.

Our design philosophy centers around a high level of refinement and focus on efficiency, creating bikes that are made for goin' fast, built to last, and are easy to work on. Plus, we provide extensive customization options, from build kits to frame colors. This means you're building a bike that's dialed for you.


Our frames are designed, tested, and built in-house here in Denver, Colorado. This unique holistic structure allows us to link all aspects of the process to ensure quality and take advantage of manufacturing efficiencies. We are also proud to take the lead on the reshoring movement in American manufacturing. Take a photo tour of our manufacturing process.

Who Started Guerrilla Gravity?

Kristy Anderson

Ride It Grrrl Director
Kristy rode and raced mountain bikes for a long time then moved to NYC and got distracted. Then she moved to Colorado and re-discovered them and was like "Whoa, these things are fun! They're so pluuush."

Matt Giaraffa

Chief Enginerd
Matt's going to make sure that you get a high performance mountain bike that you're stoked to ride for a long time. He used to design race cars and airplanes, now he's applying all that knowledge to his passion for bikes. He hates the word "plush."

Will Montague

El Presidente
Will decided to ask a few questions, "Why do companies keep making mountain biking more expensive? Why can't you get exactly the bike you want out-of-the-box? Why are so many bike companies so distanced from their riders?" Then he told Kristy and Matt about the idea and they said "Let's do it." Now we're doin' it. He doesn't understand why everyone doesn't like bikes and punk rock shows.
