2015 Trek 27.5 EX and Lush Announced

For 2015, Trek will offer the EX with 27.5in wheels in three alloy-frame builds, as well as carbon versions at the 9.8 and 9.8 levels.

The Fuel EX 9, 9.8 and 9.8 will also come equipped with Trek’s new RE:aktiv suspension technology co-developed with Fox and Penske Racing Shocks.

This new shock uses Trek’s proprietary DRCV air spring and adds damper technology that boosts low-speed compression to improve pedaling performance while allowing the shock to handle larger, high-velocity impacts without feeling harsh.

The women's counterpart to the Fuel EX, the Lush, will also be available with 27.5in wheels.

From Bike Rumor:

The biggest difference that sets the RE:aktiv shock apart from the pack is the inclusion of what Trek and Penske refer to as regressive damping. Most mountain bike suspension is either progressive or digressive, while regressive damping is supposedly true F1 technology that has trickled down to Indy car, NASCAR, and now, well mountain bikes. On the track, regressive damping provides firm support on the straights and corners but as soon as it encounters a bump, the shock instantly opens up to plush, smooth progression. This all happens extremely fast and as Trek points out, “delivers on the unrealized potential of an inertia valve.”

Once Trek and Penske had worked out the damping they wanted to incorporate into the RE:aktiv shock, Fox was brought in to package it into a patent-pending exclusive design only for Trek bikes.

“The thing about Penske is they’re completely focused on being a racing company. So what we’re doing is leveraging their R&D resources and turning that into almost an extension of our own capabilities,” said Trek Director of Suspension Development Jose Gonzalez. “The combined effort with Fox providing the production expertise has produced just an outstanding shock.”

Of course, the bike is fitted with amazing characteristics all around.

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.	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.	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.
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.	Dropper posts are great for while-you-ride seat height adjustments, but cable routing has always been an issue. RockShox Reverb Stealth routes the hydraulic housing directly through the frame for the sleekest setup you've seen.	Our robust and confidence-inspiring rear thru axle is about 35% stiffer than an open dropout design. And now, a thru axle wheel change is actually quick and easy, thanks to a tabbed guide in the frame's dropout.
