BIKE BOMBTRACK TENSION ONE
SKU: BI4293
Introducing the Bombtrack Tension 1, the ideal bike for those eager to climb the cyclocross ranks without feeling overwhelmed. This entry-level racer is designed to give you a solid foundation for competition with its lightweight yet durable construction and performance-oriented features. Built around a sturdy 6061-T6 double-butted aluminium frame, this bike is engineered to handle whatever the course throws at you, while the full carbon fork impressively dampens vibrations, ensuring that riding remains smooth and enjoyable. Plus, with rack and fender mounts, you can easily customize your ride for different conditions, whether you’re commuting or hitting the trails.
The heart of the Tension 1 is a reliable SRAM Apex groupset that features a single-chainring, 11-speed gearing system. This setup is tailored for racers wanting versatility, striking a balance between speed and control, allowing you to maintain your pace during those critical mid-race moments. The gearing is wide enough to tackle tough climbs without feeling too stretched even after the finish line when you're just out for a leisurely ride.
Equipped with SRAM APEX flat mount hydraulic disc brakes, the Tension 1 ensures excellent stopping power regardless of weather conditions. The 140 mm rotors add an extra layer of confidence, giving you the ability to brake later and harder when needed, be it in a race or during your weekend adventure. The bike rolls on reliable WTB ST i19 double-wall wheels, which provide ample durability and support with their 32h configuration, ideal for rough gravel paths.
One of the standout features of the Bombtrack Tension 1 is its tires. The XS-S models come with VEE TIRE XCX 120 TPI TLR 32-584, and the M-XL options feature CHALLENGE GRIFO TLR 33-622, both tubeless-ready. This combination means you can enjoy superior traction and comfort, while the ability to run tubeless means less chance of flats and reduced rolling resistance, allowing you to maintain your speed on those rough-and-tumble gravel roads.
This bike isn't just about performance, though; it appeals to a wide range of riders. Whether you're a beginner looking to get into cyclocross or an experienced enthusiast who wants a dependable rig, the Tension 1 is designed to cater to your needs.
Riders who have put the Tension 1 to the test often rave about its balance of speed, comfort, and agile handling, making it perfect for those looking to improve their skills and tackle competitive events. Overall, the Bombtrack Tension 1 is an excellent choice for anyone looking to take their riding experience to the next level, blending performance with user-friendly features, making it a solid investment right from the start.
