Big Swingin' Rippers Al and Charlie ride the new connector trail from Packer Saddle to Pauley Creek in the Sierra Buttes

We freakin' love to ride mountain bikes. We also spend a lot of time on our road and gravel bikes, but in our minds, nothing beats riding in the woods or high up in the back country. We pride ourselves in being the "go to" shop for your mountain bike needs. We have a dedicated workbench to professionally service suspension forks, shocks, and disc brakes - we do this all in house. We also have the City's deepest fleet of demo bikes from Yeti, Transition, Orbea, Giant, and Niner. Doesn't matter if you are a newbie, or a seasoned ripper - we've got your back. Come by and demo the best bikes on the planet.

LOTS of Rad New Demo Bikes

We're constantly updating our stellar fleet of demo bikes - some of the recent inductees to our fleet include Niner's completely redesigned RIP9 RDO trail slayer, Yeti's new SB130 and SB100, including Beti versions for the Lady Shredders, Yeti Beti SB5, Liv Intrigue Advanced women's trail bike and its men's counterpart, the Giant Trance Advanced. Get down here are try the best mountain bikes on the planet. We might also suggest you grab a demo and take it up to our new spot in Fairfax, The Lodge.

Shop Video

Special thanks to San Francisco's 12FPS for our new shop video featuring music from The Black Lillies - we wanted to create a brief movie introducing folks to our retail store, legendary workshop, and guided mountain bike tours - thanks for takin' a look.

Our workshop - the heart and soul of our business.

Not really anything new, but our service department is the essence of our operation. Our entire staff is competent in the workshop, with the best tools and up to date training to make your bike purr. Our technicians have been with us years, not months, and are passionate cyclists who empathize with other riders.

We can handle any job, but thrive on sophisticated work: suspension overhauls, pro builds, custom wheels. Parts are cleaned in an industrial grade ultrasonic cleaning tank, suspension forks are removed from the bike and overhauled on a dedicated work bench, and bearings are installed with precision presses. We are as comfortable upgrading a Di2 system with the latest firmware as we are installing a basket on your townie bike.

We love that our shop is just that: a work-shop. It's not a clean room or a laboratory. We work on bikes here. And bikes are a wonderful mix of metals, rubber, carbon fiber, plastic, dirt, grease and oil. Our workshop is open, clean, well lit, and organized. But, we don't cry when grime from your bike falls on the floor, or we get some grease on the workbench.

We make your service experience a pleasure from start to finish. We do a thorough triage on every bike at intake to determine what work should be considered. We provide a clear, written estimate of all work before we begin. We communicate with you - like us, we assume you don't like surprises. We're happy to schedule appointments (call or e-mail us) for your service job, minimizing down time. We can also pick up your bike for service, and return it to you when the work is done :)
