The full potential of the engineering staff is evident in the all new, full suspension Crossfire model which becomes not only more race ready but also somewhat of a trailblazer thanks to innovative solutions throughout. To render the bike more agile, reactive and efficient the Crossfire adopts the shortest chainstays available on the market. Measuring an amazingly short 428mm the Crossfire is able to locate the rear wheel closer to the bottom bracket than nearly anything else in cross country mountain biking currently in terms of a full suspension ride. The resulting performance gain is impressive and renders the bike extremely competitive in even the most demanding scenarios.

Shortening the chainstay to a mere 428mm on a full suspension bike was no small feat as traditional suspension link construction places additional hardware between seat tube/bb and the rear tire. The Lee Cougan engineering team developed an innovative and very atypical solution to overcome such an obstacle by moving the chainstay bridge in front of the seat tube. Not only does this revolutionary design allow for a shorter chainstay along with all of its performance advantages but it makes for optimal torsional rigidity while allowing for tire clearance up to 2.25”.

Moving the chainstay bridge forward allowed for better and more race worthy geometry but the design of the link and rear triangle together make for unsurpassed efficiency. The horst link was eliminated in favor of a solid semi triangle. To compensate for its removal and eliminate the negative side effect that derives from “bobbing” the new 2nd Gen 3D link as well as the form and construction of the rear triangle have been designed specifically to reduce to a minumum the movement of the top link and therefore less flex of the seat stay. The result: more efficient, comfortable race-ready suspension performance. The Crossfire’s rear triangle design benefits from Lee Cougan’s True Internal Cable Routing system that see cables pass from BB directly into chainstay, leaving them exposed for only 1cm.

Not only for a cleaner aesthetic the routing design aids in protection from external elements as well. Internal cable routing finds its way into not only the frame but also the cockpit as the Crossfire cements itself firmly among the first in the mtb world to route transmission and brake cables within the stem and steer tube. The 1.5” upper and lower bearing with subsequent oversize headtube design was incorporated specifically for this puprose. To keep both frame and cables safe the internal block system prevents instances of oversteering from causing damage. While the rear triangle represents a solution to render the handling more reactive and immediate, the front end was developed in order to offer more stability. For pure cross country courses are becoming increasingly extreme and a more open head tube angle aids in overcoming difficult terrain. XC marathon riders too will welcome the plush yet reactive front end with a 68.5° head tube (for 100mm travel fork) by rendering the terrain more manageable after hours in the saddle.
