Founded in 1983! Welcome to the oldest Mountain bike club on the PLANET! Since 1983, CBMBA has been creating, maintaining, advocating, and putting mad love into over 450 miles of single track in the North end of the Gunnison Valley. Crested Butte is one of the founding homes of Mountain Biking. We are Bike Culture! From the streets in Town to the miles upon miles of track surrounding our Towns, we eat, sleep, and breathe Bicycles and Trails.

All trail users benefit from the work and advocacy that CBMBA puts into our breath-taking backyard.  Help us to keep doing what we do with a donation, membership, or by volunteering at one of our workdays/events.  Check out our updated Master Plan, learn why this club is responsible for and has shaped Crested Butte culture, and get on track with the greatest trails and rides.

Support CBMBA’s Winter Grooming Proposal

Check out CBMBA’s proposal to the Gunnison National Forest Ranger District to groom Fat Bike (and all users) Trails this Winter in several drainages surrounding Crested Butte.  We’re partnering with Al Smith and Camp 4 in Cement Creek, the Chamber and CBMR for Fat Bike Worlds, and proposing to provide a better user experience in the Gothic drainage, and true Fat Bike Singletrack in the Brush Creek – Strand/Farris area.  Click the image below to see our Mission, the full proposal, how to support, and where/who to send an email or write a letter to.
