DirtLabs is a team of rider/mechanics obsessed with bikes and the science-meets-art of dialed suspension. DirtLabs was founded by Mike “Luby” Luebesmier. Luby has a long history of wrenching. His focus on suspension started in 2004 at the Shock Treatment Center in Minneapolis rebuilding and tuning Rock Shox, Manitou, Marzocchi and other brands. As the industry and technology evolved the stack of worn seals and wipers next to Luby’s bench piled up. In 2006 Luby went to Maverick Bikes to handle suspension builds, tuning and repairs. Working directly under Maverick/Rock Shox founder Paul Turner and machinist/engineer Frank Vogel Luby deepened his understanding of suspension from concept, R&D and testing to production and tuning. It was time to take this knowledge base and strike out on his own.

In 2008 DirtLabs opened and quickly became the go to shop. Word of their ability to give bikes that magic feel quickly spread with riders, bike shops and suspension manufacturers and they soon outgrew their shop. In 2012 they added staff and equipment, but kept the same low key vibe and attention to detail.In 2016, Dirtlabs made the move out of Boulder to Longmont for a bigger and more efficient facility. They’ve become a trusted service partner for Fox, Cane Creek, RockShox, MRP, Manitou and more, as well as provide service on most all major brands.

Whether you’re hoping for a spot on the podium at the end of the day or just a spot at the bar after an epic ride Dirtlabs can make your ride better, sweeter, plusher — Stop by, email or give them a call. They’ll set you up.


Mike “Luby” Luebesmier

Back in 2004 at the Shock Treatment Center in Minneapolis Luby rebuilt and tuned Rock Shox, Manitou, Marzocchi the handful brands out there. In 2006 Luby went to Maverick as a suspension technician. Working directly under Maverick/Rock Shox founder Paul Turner and head machinist/engineer Frank Vogel allowed Luby to learn suspension from concept and R&D through testing and tuning. In 2008 Luby started DirtLabs and has watched the industry explode with dozens of brands and hundreds of products available — and Luby has worked on all of ‘em. Luby is laid back and low key, and takes good care of his customers, his staff and his family.


Chris Harris

Business Operations
Chris began his professional career as an audio and acoustical engineer:

“Audio signal processing and suspension theory are very analogous.  [Spring] rate, compression, and rebound damping exist in both fields.  Low-speed and hi-speed signals in audio are the same low-speed or hi-speed hits on a bike. It’s input versus output really and keeping your wheel on the ground is the same as leveling an audio signal. Having an in-depth understanding of both has provided me with a unique perspective on suspension theory and mechanics”

Chris is s former lead technician and is still involved in problem child fork or shock repairs. Chris also heads up most of our marketing efforts and keeps up our brand exposure in the biking community. Our go to guy for in-person suspension setups, Chris, helps riders get the baseline established and then fine tune to resolve issues they are feeling on the trail. His Yeti sb6 sees a lot of trail time as well as a race in the Enduro circuit here and there

James Liepolt

Technician / Purchasing

James started his career in the bike industry back in 2007. Within the tight confines of his college dorm room, James was often found repacking bottom brackets, lacing wheels, and bleeding brakes for his friends. Since then James has expanded his mechanical expertise in various bike shops and classrooms with the continual drive to further his diverse knowledge in the industry.
James hails from an island off the coast of Maine where he developed his passion for cycling and the outdoors. After moving to Colorado in 2014, James dove head first into mountain biking and suspension which led to his additional to the team in early 2018. When not sporting the musk of suspension oil, you can usually find him on two wheels, but not always on a mountain bike. James occasionally rides his road or gravel bike to his favorite fishing spot up the Poudre River.
