| Features | OCLV Mountain Carbon: Every carbon mountain bike we make is built using OCLV Mountain Carbon. We start with our patented OCLV process, then tailor it to the rigors of off-road use. We reinforce the right areas with unique materials, while still preserving the light weight and great Trek carbon feel. It’s tougher carbon, built for the trail. We have the deepest carbon fiber know-how in the industry. Our carbon engineers and designers have pioneered new processes, obtained over 52 carbon-specific patents, and built more carbon bikes than any other manufacturer. No wonder our carbon mountain bikes are the best in the world.
OCLV Mountain with InTension: Trek’s proprietary InTension material is an advanced low-density, ultra-stiff material built directly into the layup of complex shape and molding areas. It has 4X the flexural strength of a similar carbon-only structure, and is 8X stiffer. InTension acts as the web of an I-beam-like structure, transferring loads between two flanges. We use it in ultra-high-load, high-bending problem areas like pivots, bottom brackets, and seat tubes. InTension is the latest in a long line of Trek mountain biking solutions Invented, engineered, and perfected in Waterloo, WI.
OCLV Mountain tested: Every OCLV Mountain frame endures the same punishment: 21 separate fatigue, load, strength, and energy tests (15 more than the industry standard), followed by our Anvil Strike Test that simulates rock kick-up in susceptible areas of the frame. If a frame doesn’t pass even one of the tests, it’s back to the drawing board, and then we test again. Each of our carbon frames is designed and built for a specific category (Cross Country/Trail, Technical Trail, or Gravity) that determines what force we apply to each of our 21 frame tests. It’s how we ensure our XC race bikes are light enough to podium, and our gravity bikes are plenty strong enough to survive the run.
Carbon Armor: Sometimes you need a little extra protection, so we developed our light, tough external Carbon Armor polymer shield. It provides reassurance when you know your down tube is bound to take some abuse.
Integrated frame protection: Removable, replaceable down tube guard increases damage resistance, and allows riders to shed valuable grams on race day, or to replace the guard as necessary. We build fork bumpers directly into the frame for a sleek, streamlined setup with enhanced durability and performance. Integrated chainstay protection minimizes chain-slap noise and keeps the frame fresh underneath.
World champion geometry: The results speak for themselves: Trek World Racing team riders have ridden Session to multiple World titles.
ABP Convert DH: Other full suspension systems firm up under braking, reducing your control when you need it most. Trek’s patented Active Braking Pivot solves that by keeping your suspension active whether you're on the brakes or off. ABP DH features a wider hub stance to accommodate wider 157x12mm DH wheels and is at least 30% stiffer than an open dropout design. A conversion kit available at your Trek retailer will give you the option to switch to 150x12mm. When your suspension stays active under braking, you stay in control. You can brake later in a turn, maintain better rear wheel traction in stutter bumps, go faster, and just have more fun. Try it on any other system: find a downhill with stutter bumps. Apply the brakes and feel the suspension stiffen. Your rear wheel will skip across the top of the bumps. Now, try it with an ABP-equipped bike. Feel the extra control, and imagine how much faster you can go. That’s the ABP difference. We were delighted when ABP was awarded US Patent # 7,837,213 in 2010. But fun as it's been to add the patent number to our frames, the real satisfaction comes from building ABP into every full suspension bike we sell, because it means you get to ride a better bike.
157x12: Wider 157mm hub for greater wheel strength, paired with the DH-standard 12mm thru axle.
E2 tapered head tube: E2 is the evolution of the traditional 1-1/8" headset to a tapered head tube, fork, and headset system. E2 tapers from a 1.5" lower to a 1-1/8" upper headset to provide more material where it matters most, resulting in a stronger, lighter frame with point-and-shoot control.
MicroTruss: MicroTruss housing guides are built directly into the frame, for the lightest, cleanest external cable routing.
Routing options: Session’s Internal Control Routing takes care of messy brake and derailleur cables by routing the housing directly through the frame itself. It’s the cleanest, quietest setup for full-on race day performance. Don’t want to route internally? Skip the traditional method and opt for Session’s exclusive MicroTruss housing guides. Trek’s patent-pending technology is built directly into the carbon structure itself, acting as a routing channel. MicroTruss is stronger than the structure it replaces, is virtually indestructible, and is yet another Trek first.
Mino Link adjustable geometry: Mino Link is an adjustment link located on the EVO Link that allows you to fine tune head tube angle by 1/2° and BB height by 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance.
Full Floater: Most suspension systems attach the bottom of the shock to a fixed frame mount. That fixed mount can contribute to a harsh ride. We solved that with Full Floater, attaching the shock to two moving linkage points so it can better respond to bumps across a wide variety of terrain. It feels like more travel, but it's not. It's smarter travel.
Carbon EVO Link: EVO Link is Trek’s evolution of the rocker link from the plate-and-bolt style used on most suspension bikes to a one-piece rocker link. This lighter link provides a stronger connection point between the front and rear triangles, creating a stiffer frame for greater control with minimal weight.
ISCG mounts: International Standard Chain Guide mounts offer easy chain guide installation and adjustment.
Coil suspension: Coil shocks are typically more sensitive to differences in terrain than air shocks, resulting in higher performance.
Single ring and chain guide: Downhill-specific drivetrain setup keeps it all together through the toughest terrain.
