| Features | 500 Series OCLV:
Over two decades ago, Trek engineers developed our Optimum Compaction, Low Void carbon manufacturing process, enabling us to produce carbon bikes with consistency and quality previously thought impossible. To this day, Trek OCLV Carbon continues to lead the industry, advancing what's possible in carbon frames. Each level of OCLV offers the best ride for the money, thanks to an optimal balance of areal weight, stiffness, and compliance. 500 Series OCLV achieves a superb balance of light weight, strength, and stiffness that's perfectly suited to the sophisticated frame technologies that distinguish Trek frames.
Net Molding:
An OCLV Carbon exclusive. Our proprietary molding process allows us to create the precise, extremely-tight-tolerance shapes required for the best ride quality and performance, like our integrated cupless BB90 bottom bracket and our cupless Net Molded head tube.
Electronic drivetrain optimization:
Full internal routing with a proprietary seatpost electronic battery mount allow for a perfect interface with the industry-leading drivetrain systems without a single cable tie or strip of tape. It's the most seamless component integration in the industry.
BB90:
BB90 is the widest bottom bracket available on a road bike. This Trek-exclusive carbon BB makes the frame lighter, stiffer, and quicker to accelerate. BB90 eliminates the need for extra inserts and parts in the bottom bracket/frame junction. Fewer parts mean a lighter frame. And a lighter frame means a faster ride.
DuoTrap compatible:
DuoTrap seamlessly integrates the computer sensor into the frame to measure speed, distance, and cadence with no added aerodynamic drag. It works with all the major ANT+ wireless technology players, including Bontrager, Garmin, PowerTap, and SRM.
Ride Tuned Seatmast:
Our Ride Tuned seatmast is the lightest, most comfortable solution for day-in, day-out performance and comfort. The no-cut design eliminates traditional seatpost clamping forces, so we can use less material at the seat tube junction, resulting in a lighter frame. Most seatmast systems have to be cut, leaving little or no room for adjustability. Our Ride Tuned seatmast system has more than 10cm of adjustment, making it the most adjustable system on the market.
IsoSpeed fork:
It's a one-two punch: generous ride-tuned sweep and shape increases compliance for a smoother ride, and unique dropout placement optimizes the wheelbase. An extra curve above the dropout in our swept-leg design creates a smaller angle to the direction of road vibrations. This angle increases fore/aft compliance, better positioning the fork leg to absorb road force rather than transmitting it straight to the rider. We’ve also increased fork lateral stiffness, maximizing both smoothness and control.
E2 head tube and fork:
Our E2 head tube tapers from a 1.5" lower bearing to a 1-1/8" upper bearing, and is wider side to side than front to back. This asymmetric steering system minimizes weight while maximizing power transfer and keeping the fork stiffer under cornering loads. Result: a more powerful and confident ride.
IsoSpeed decoupler:
At the core of Trek's endurance comfort technology is the IsoSpeed decoupler, the result of an 18-month study of how a racing bike performs over rough roads, and how that performance affects the rider. Trek engineers designed a decoupler that allows the seat tube to rotate independently from the top-tube-to-seatstay junction, increasing vertical compliance to twice that of our nearest competitor, without compromising pedaling efficiency. Result: you can ride harder, longer.
E2 asymmetric steerer:
A fork has two competing directives: provide lateral rigidity for precise cornering, and offer vertical compliance to absorb road vibration. Trek’s full-carbon E2 asymmetric fork/steering tube is the first steerer specifically shaped to manage both. The fork is wider side-to-side to stiffen under cornering load, narrower front to back for comfort.
3S integrated chain keeper:
Our 3S chain keeper is integrated directly into the bike frame. It's an elegant solution that provides flawless shifting even on rough roads and under heavy loads. No more standing on the side of the road, covered in grease, unwedging your dropped chain as competitors race by.
Power Transfer Construction:
Get the most out of every pedal stroke with Power Transfer Construction. This Trek innovation applies more of your pedaling power to the road by optimizing the head tube/down tube/bottom bracket/rear wheel connection. It's made possible by two features found only on Trek race performance frames: our asymmetric, wider-at-the-bottom E2 head tube, and our BB90 bottom bracket, the widest available on a road bike. Power Transfer Construction connects the two with a wide, ultra-stiff down tube that transfers more power, for more speed out of every pedal turn.
Performance cable routing:
Trek’s performance cable routing is highly engineered for unshakable precision and the real-world performance that comes from better compatibility with current drivetrains. Optimal routing through the frame provides flawless shifting, better braking, sleeker aerodynamics, and easier assembly and maintenance.
