Freshies! New Demo Bikes For Your Enjoyment

Oh Snap! We just refreshed a few of our demo bikes - We now have a large Transition Smuggler, featuring a new, 2018 Boost Fox Elite 34 140mm fork, Shimano SLX 1x11 drivetrain and brakes - this is a super fun alloy 29'er trail whip. Also new is a small Yeti SB45c with the new Rock Shox Pike with Charger 2 damper, and SRAM GX Eagle 1x12 drivetrain - this is basically our way of making a Beti version of the venerable SB45 for the lady shredders. We've tuned the suspension and contact points to better suit you girls. Finally, we updated our medium SB5 Turq series trail ripper - this bike also has the new Pike with Charger 2 damper and SRAM GX Eagle, and Reverb dropper with 1 x remote.

Meet Elby - Our Favorite E-Bike

We've been a big fan and top dealer of Bionx e-bike retrofit kits for years. When we learned Bionx created a sister company to make a complete e-bike, we couldn't wait to see the product. Come ride our Elby demo and be blown away. If you ever thought "it would be cool to have a landspeeder from the movie Star Wars", Elby is pretty damn close. 500 watt silent hub motor, CANBUS digital control, hydraulic disc brakes, regenerative braking, German LED lighting - this thing absolutely rips - it's a stone cold car killer.

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 :)
