Mountain Frames

Developed in conjunction with freeride legend Matt Jones and taking its name from the most rough and tumble piece of Marin County, the San Quentin collection lives up to the notoriety of the namesake maximum security California State Prison. Blending the strength an style of our Alcatraz dirt jump frame with the natural trail savvy of the best hardtails, the San Quentin family of aggressive trail hardtails is the perfect mash-up for the modern trail rider. TWO FRAME SIZES Newly updated for 2022, the Alcatraz is now offered in either short (385mm reach) or long (430mm reach) to better fit a wider range of riders. FUN, STRONG, AWESOME Usually in life you can't get everything you need, but with the Alcatraz dirt jumper you can – a fun, burly bike that will let you explore what is possible with two wheels. IF MATT JONES SAYS IT'S GOOD... What better way to know a product will perform than having it proven on the FMB World Tour by Matt Jones?

Big mountains, epic passes, and all-day ripping descents. If you live for the alpine adventure and gravity-fueled downhills, look no further than the Alpine Trail series. Updated for 2021, the Alpine Trail is built around the longest travel version of our critically acclaimed MultiTrac platform with progressive slack headtube/steep seattube geometry, low-slung aluminum frames, and 29" wheels. The Alpine Trail is here to conquer all singletrack in its path. Unidirectional Carbon Fiber Frame - Alpine Trail Carbon 1 and 2 models feature high modulus carbon fiber and monocoque construction to deliver the strongest and stiffest Alpine Trail to date. Modern Geometry - The Alpine Trail is at the cutting edge of aggressive enduro geometry, bringing you the best long travel bike for the job. A 63.5° headtube angle, 78° seat tube angle, short 430mm chainstays, and a long front center unlock the trail for pure long travel bliss. Functional Long Travel - The Alpine Trail was built to give riders long travel with no sacrifice in pedaling efficiency, providing a bike that will outshine the competition on the climb and still allow you to hold it wide open on the descents.

The El Roy is the ultimate aggressive steel hardtail that’ll get you to the top, and then really shine on the way down, with a spicy mix of progressive geometry and supple steel. The classic robust yet forgiving character of chromoly steel meets modern-day long and slack geometry, a match as perfect as mountain biking and post-ride burritos. This new 29" wheel trail slayer was purpose-built for silly fun days in the woods, no matter the conditions. Use it as a back-to-the-roots, all-in-one trail slayer, or as that perfect "n+1 bike," on days when the full suspension bike stays at home in the shed. Named in honor of our favorite post-ride taqueria, the El Roy is overflowing in solid spec choices, all wrapped up with a stout Series 3 double-butted and formed CrMo frameset. Grab one of two frame sizes, Regular or Grande, and enjoy the delicious goodness that we've cooked up. TECHNOLOGY: SERIES 3 CRMO FRAME The El Roy is built on a stout Series 3 4130 CrMo frame with investment cast dropouts, integrated drop-in headset, external brake and hose mounts, all fully ED coated for longevity. GEOMETRY Gravity-oriented geometry, with a 63° headtube and 78° seattube angles, 44mm fork offset, and long reach measurements (Regular = 480mm, Grande = 510mm). TWO SIZES Regular and Grande frame sizes fit a wide range of riders, with included 150mm (Regular) or 170mm (Grande) dropper posts. INVESTMENT CAST DROPOUTS Custom investment cast CrMo 148x12mm Boost thru-axle drop outs provide strength and stiffness where you need it most. TOPTUBE STORAGE MOUNTS Bosses on the underside of the top tube give the rider the option to mount tools and other accessories in a tidy and secure fashion.

The Rift Zone is our most speed oriented MultiTrac bike, created for the rider looking for the speed and roll over capabilities of 29" wheels in a trail capable package. Long, low, and slack trail geometry is more aggressive than an XC race bike for more control at top speed, and more fun while chasing seconds.
