Today, I am honored to bring you a review of a crossover mountain bike that combines speed, handling, and comfort – the Supercaliber SLR 9.9 Flight Attendant Gen 2 from Trek Bicycles.

In the following evaluation, I will comprehensively analyze this bicycle from multiple aspects such as exterior design, performance parameters, and riding experience. Let’s embark on this journey of speed and passion together, experiencing the infinite charm and possibilities brought by Supercaliber SLR 9.9 Flight Attendant Gen 2.

Riding Experience

On a weekend morning, I decided to temporarily escape the hustle and bustle of the city. Riding my new companion – Supercaliber SLR 9.9 Flight Attendant Gen 2, explore the unknown beauty hidden on the outskirts of the city.

As the wheels slowly rolled, I gradually moved away from the tall buildings. Entering a peaceful suburban path, the sunlight filtered through the sparse clouds and sprinkled on the winding path, adding a touch of mystery and anticipation to my journey.

Climbing

Soon, I encountered an uphill section, which was a necessary path leading to a small hill. Although it was a bit steep, Supercaliber’s transmission system gave me enough confidence. I adjusted my breathing, increased the pedaling force, and felt the continuous power coming from under my feet.As the height gradually increases, the surrounding scenery becomes more open and magnificent. I stood on the mountaintop, overlooking the fields and villages beneath my feet, filled with the joy of conquest.

Descending

The downhill section is even more exhilarating. I raced down the winding mountain road, feeling the excitement of the wind whistling past my ears. Supercaliber’s braking system is sensitive and stable. It allows me to stay calm on the highway, deal with bends and obstacles. Every sharp turn is like a seamless dance with a bicycle, as we together perform the legend of speed and passion.

As the sun gradually set in the west, I rode my Supercaliber back to the city. Although the body is somewhat tired, the heart is filled with satisfaction and joy. This cycling not only allowed me to escape the hustle and bustle of the city, but also rediscovered the beauty and infinite possibilities of life.

Specifications

The Supercaliber SLR 9.9 Flight Attendant Gen 2 features IsoStrut technology, which connects the main frame to a rear seat strut without a pivot, providing approximately 80 millimeters of rear wheel travel. This design combines efficiency, traction, and fatigue resistance to keep the racer fresh and in control. The IsoStrut integrated suspension system provides sufficient travel to maintain control, fully adjustable like standard rear shock absorbers, but without the weight penalty of a fully suspended bicycle.

The SLR OCLV mountain carbon framework uses high modulus carbon fiber layers, reducing material usage and thus reducing weight. At the same time, the internal conduit was omitted for cable routing, minimizing material usage and minimizing weight.

Flight Attendant technology analyzes data from sensors on the front fork, shock absorber, and crankshaft. Automatically adjust your suspension settings between the open, pedal, and locked positions, no need for you to worry. The bicycle is equipped with a crank based power meter, allowing Flight Attendant to collect rider and trajectory inputs in real-time.

Adaptive ride mechanics compiles your previous ride data to calculate personalized effort zones and achieve fully personalized suspension customization. This bicycle is designed specifically for racing and has a relatively light overall weight, making it suitable for long-distance competitions. Equipped with SRAM Level Ultimate 4-piston hydraulic disc brake, providing powerful braking force and stable braking performance. According to different sizes, the rear transmission adopts SRAM XX SL Eagle AXS T-Type or SRAM XX SL Eagle AXS, ensuring fast and accurate shifting. Provides convenient cable routing ports for adding and upgrading seat cushions, allowing you to easily lower them in complex terrains.
