The bike feels more alive than the day I picked it up new. Mikes knowledge and skills have helped open up the riding envelope for more fun and while adding more control and margins for safety. My riding has improved with the changes made. I will be bringing my other bikes to him.

Great service by Mike. He had me wait until parts arrived and only was without my bike for a couple days. Full service like the good old days!

My go to for all things suspension related. I first met Mike at another shop and learned a lot from him. Since then I've stuck with him whenever I need something done to my fork or shock. The best part is Mike will work with you one on one to help you meet your suspension goals!
