MOUNTAIN ALUMINUM Mountain competition bicycles that combine maximum strength with minimum weight for peak performance. Our leadership in mountain bike design is exemplified by our bonded aluminium mountain bikes. We use premium aluminium alloys like Easton 7000-E9 and Alcoa 6061 T-6 to guarantee superior strength and minimal weight. These double buttered aluminium tubes are then bonded to Trek’s exclusive squeeze cast aluminium lugs to assure precise alignment of the frame and increased rigidity for better performance. This year our mountain bikes sport significantly larger headsets which are designed to be stronger, distribute stress better, and create a stronger overall frame. We’ve also increased the blade size of our forks to provide a tighter more responsive ride. These changes provide a noticeable improvement in both handling and performance. All our aluminium mountain bicycles now feature exclusive Triple-Tech top tube cable routing which reduces the possibility of dirt clogging the gear and brake cables and simplifies maintenance. Finally our frame geometry with 71° head and 73° seat tube angle, produces an aggressive combination of frame strength, hill attacking power, and reassuring control on descents. Off-road terrain can be very tough. These bicycles are designed to be tougher.

SINGLE TRACK High-performance bicycles for the serious off-road enthusiasts. Trek’s Single Track Series remains a front runner in mountain bike performance. To stay in the lead, our Single Track bicycles now feature our Optimal Dimension tube design. Our research has proven that as we increase the diameter of a tube, while decreasing the wall thickness we create a stronger, stiffer tube that weighs less. This is the principle behind our new OD technology. With this design aour Single Track bicycles provide maximum strength and rigidity at minimum weight. This gives the frame the toughness that is needed when pounding over rough terrain and the rigidity necessary for efficient transference of energy from your legs to the trail. Geometry also plays an important role in the overall performance of the Single Track. The assertive geometry of the Single Track, with a 71° head and 73° seat tube angle, creates a rigid, highly responsive frame which allows you to aggressively attack the turns, hills and descents. All our Single Track bicycles now feature exclusive Triple-Tech top tube cable routing which reduces the possibility of dirt clogging the gear and brake cables and simplifies maintenance.
