MBoSC / IMBA Joint Membership
MBoSC is a chapter of the International Mountain Biking Association (IMBA). Your membership dues will be shared with IMBA to support advocacy and legal representation on the local, national, and international level.

By growing our membership we increase our leverage in negotiations with elected officials and land managers. Please join MBoSC/IMBA so that our collective voices can be heard and we can work together to provide more mountain biking opportunities for you. MBoSC and IMBA sincerely appreciate your support of trails and mountain bike facilities in Santa Cruz County.

MBoSC members receive benefits at local bike shops—learn more here!

NOTE: Donations to MBoSC are separate from MBoSC/IMBA membership dues. Donor information will not be placed on a membership list. Donations to MBoSC remain in the local community to support our trail efforts here in Santa Cruz County. Donations fund expenses such as web hosting, office supplies, insurance, trail building equipment, bike park contributions and event costs. Click here to donate.


Email List
The MBoSC email list is a forum of discussion and a source of news about issues affecting mountain bikers who enjoy riding and trail building in the Santa Cruz area. Topics covered on the list include land access issues, trail work status and recruitment, as well as social discussions about rides, trips and events. Browse list archives.

Messages sent will forward to all members of the list. The traffic is generally light, so it won’t overwhelm your inbox. There are several notification options for receiving messages, including no notifications at all, notifications for each message, daily summaries, and combined updates. The list gets no spam, because it is both subscription-moderated (no one can join unless a human approves it) and membership-semi-moderated (only list-members’ messages are sent out to the whole list automatically; other messages are seen and must be approved by a human).
