With raucous off-road ability and a Sherpa-like carrying capacity, it’s ready for expeditions in the high mountains.

Fast-rolling 29" wheels plus the chance of using oversized 27.5"+ tires give you the option to experiment with home-based modifications. As if these features were not already enough to hit the trails, the bike comes with a dropper post and suspension fork, avec plaisir.

The Passionate Pioneer It will steel your heart. The classic TransAM returns! After a seven-year hiatus, the reliable trail-shredding hardtail is back in the lineup for a limited time. Now with modern geometry, dual 29-inch wheels, a capable build spec or frameset options, and two classic color schemes, this will be one to hang on to and pass down for many generations. The updated geo encourages hard-charging but rewards thoughtful line choice. It orchestrates a fast-paced ballet through the landscape of your choosing. The new TransAM is ready for the core rider looking to get back to their roots. SIMPLE IS FUN For the rider who loves refined simplicity with the feeling of the wind in their face as they rip beautiful ribbons of terra firma in both directions, we give you the TransAM. The TransAM brings a feeling of nostalgia and reminds its rider of that first taste of freedom when they were young. For those that watch The Wizard of Oz while listening to the dark side of the moon. For the Off-Road Cyclist. For the person who doesn't always have a plan but knows that whatever lies ahead will be a most excellent adventure. The TransAM pays homage to the free spirits of yesteryear who found rolling through the mountains on two wheels to be the best way to experience life. LESS IS MORE Tech keeps getting more complicated, the list of features gets longer, and the number of batteries keeps increasing. While we too are a bunch of bike nerds, excited about the latest and greatest, at our core we are mountain bikers who simply care about good dirt and good company. The new TransAM has no batteries, no motor, no apps, just a Chromoly frame that'll last a lifetime. In contrast to the times, we wanted to resurrect a bike that was clean and simple. With just enough updates and features like adjustable sliding dropouts, a UDH, and options for different wheel sizes, you can customize your bike to fit your style. Get the complete or the frame, either way, get out there and leave the fuss behind.

Dirt Jump Inspired Frame Style Taking cues from the Alcatraz, the San Quentin line up provides all the benefits of the DJ style with massive standover, slick frame tubes, and a sexy paint job. Modern Trail Geometry The slack head tube angle paired with a steep seat tube angle create a ride that will fly uphill with perfect front wheel precision but then descend like it's on rails. The balanced rider position thanks to the steep seat tube puts your weight between the wheels for impressive climbing and handling on flats, while the slack front end and short rear center help to pull you through the rough descents and corners with an intuitive feel. - Series 2 aluminum frame - SR Suntour XCM32 120mm fork - Microshift 1x9 drivetrain - Tektro M275 hydraulic disc brakes - Vee Tire Co 27.5 x 2.6" tires

Lighter weight, with up to date geometry, and engineered to the same exacting standards as the rest of our line, it packs a ton of performance in a more accessible price. GEOMETRY Inspired by the World Cup Race Win­ning Exie USA, the DV9 fea­tures a row­dy-but-not-too-row­dy 66.5° head angle and ultra-play­ful 425mm chain­stays. A low stan­dover improves fit for the inseam chal­lenged rid­er, while size spe­cif­ic seat tube angles give rid­ers of all heights an effi­cient yet enjoy­able rid­ing position. TIRE CLEARANCE Whether you pre­fer the cushy and con­fi­dent ride that 2.6" tires deliv­er or the blaz­ing speed of weight-con­scious 2.25" rub­ber, we've got you covered. INTERNAL CABLE ROUTING Inter­nal cable rout­ing used to be a pain in the ass but our inter­nal tubes make rout­ing easy. Just pop the hous­ing through and it comes out the other end, no need for swear words or a pickset. FRAME PROTECTION Our thick rub­ber down­tube and chain­stay pro­tec­tion help damp­en noise and pro­tect the frame. We've also included a sim­ple-yet-ele­gant adjustable top guide that allows you to drop the ham­mer, not your chain. 2X BOTTLE CLEARANCE The DV9 has clear­ance for two water bot­tles inside the front tri­an­gle of every size frame. Even the small. LIFETIME WARRANTY If it's our fault, we'll fix it. Sim­ple as that.
