Alpha Platinum Aluminum: Our premium lightweight aluminum is continuously cold extruded and butted at multiple points for ultimate weight reduction and superior strength. Frames built with Alpha Platinum are hydroformed to create the most sophisticated shapes for the lightest weight, and are finished using Trek's smooth-weld finishing process.
Down tube guard: Replaceable external shield protects the down tube from trail debris.
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.
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.
Alloy EVO Link: The EVO Link is Trek’s evolution of the rocker link from the plate-and-bolt style used on most suspension bikes today to a one-piece alloy rocker link.
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.
Dual crown fork: Nothing beats the stiffness of a dual-crown fork. It’s an absolute necessity for full-on DH racing.
20mm thru axle: Burly 20mm front thru axle offers ultimate steering precision.
Single ring and chain guide: Downhill-specific drivetrain setup keeps it all together through the toughest terrain.
