Alter Events

We believe that cycling is just as much about camaraderie as the activity itself.


Every Friday since 2013 |  HAPP!EST HOUR with Sklar Bikes!

Join us every Friday of the year at 5pm for our "HAPP!EST HOUR!" cycling community gatherings.

As active founding members of our local mountain bike club, The Dirt Concern of GVBC, we've learned the sure-fire way to get riders together and get things done is to provide the beverages. Come have a pint of local craft brewer Outlaw's finest selection of the week or a LaCroix Water on the house, check out the newest bike vids, meet new peeps, plan weekend rides, or discuss issues and ideas that will better our cycling community. Family friendly, bring the little rippers!



Tuesdays in Season  |  Supper Club MTB

Every Tuesday evening during the bike season join us for an all-inclusive group ride leaving from the shop @ 6pm sharp. A mini-grill lives in Stevo's truck, so a trailhead BBQ (with Sklar Bikes slingshots) follows. BYO Drinks, Grillables, and a puffy coat for once the sun goes down!

Focused to the average trail-bike rider, these rides are about having fun out in the woods with 5 to 30 of your friends.

Weather dependent with a different trail every week - make sure to follow our Instagram or call the shop the day of for updates.
