Trek Boone 5 Cyclocross Bike
Embrace the thrill of cyclocross racing with the Boone 5 Disc, a high-performance carbon race bike meticulously crafted to dominate any CX course, even those renowned on the UCI circuit. The lightweight carbon frame features terrain-smoothing Rear IsoSpeed technology, complemented by top-notch components like the SRAM Apex drivetrain, vibration-absorbing handlebar, and powerful disc brakes. These elements ensure peak performance in varying conditions, offering precision and stopping power on bumpy, muddy terrains.
Tailored for the avid cyclocross racer who seeks podium-topping performance, the Boone 5 Disc is designed for mid-air maneuvers, bunny hopping over barriers, and conquering every course. The 600 Series OCLV Carbon frame with Rear IsoSpeed enhances comfort and traction, while the hidden cable routing protects against the elements. The 1x12 SRAM Apex XPLR drivetrain, Trek IsoSpeed Cross carbon fork, and flat-mount hydraulic disc brakes contribute to the bike's cutting-edge technology.
Built for speed and podium aspirations, the Boone ensures a remarkable racing experience on every section of the course, regardless of the conditions. As you crush frites and flyovers, this bike stands as a testament to its durability, capability, and the clean shifts offered by the SRAM Apex XPLR drivetrain. With the input of cyclocross royalty, including World Champion Sven Nys and US National Champ Katie Compton, the Boone combines race-specific geometry, tube shapes, and Rear IsoSpeed to excel in all aspects of the race, including run-ups.
In the dynamic world of cyclocross, where agility and efficiency are paramount, carbon rules on the cross course, providing a lighter, more forgiving, and more efficient experience compared to aluminum alternatives. The Boone 5 Disc is a testament to this, offering a competitive edge to riders who demand the best from their cyclocross racing experience.
