Marin Quake Bike The Bike Park Gets Serious Gravity riders who have been beating up their trail or enduro bikes at the park know the difference a purpose-built DH bike makes. The Quake is exactly that, a dedicated downhill machine with a Series 4 aluminum frame running the Multi Trac 2 LT suspension platform, which moves the rear pivots from the seatstay to the chainstay. That change matters. It reduces anti-rise so the chassis stays controlled under hard braking, delivers more mid-stroke support, and gives you better feel when bottoming out on the biggest hits. The Flip chips let you tune BB height and chainstay length to your preferred setup, and the seatstay chips can be repositioned to run a 29" rear wheel if that's your preference. The build spec matches the frame's intentions. A Rock Shox Boxxer fork up front handles 200mm of travel, and the Rock Shox Vivid Coil Ultimate DH shock out back delivers hydraulic bottom-out control with adjustable high and low speed compression damping. The SRAM GX DH 7-speed handles shifting duties with the tight cassette range that gravity riding demands. SRAM Maven Bronze four-piston brakes with 200mm HS2 rotors give you the stopping power to carry speed into the park's gnarliest sections. Maxxis DH-rated rubber and SRAM's Descendant crankset, bar, and direct-mount stem keep the parts spec dialed all the way to the contact points. The 56ZS zero-stack headtube opens the door to aftermarket headset options if you want to fine tune your reach or head angle down the road.
