In the morning, the sunlight shines through the treetops, casting mottled light on my green dark toned chariot. The deep green seems to be the most secretive call of nature. I gently adjusted my helmet, put on gloves, and stepped onto this Trail mountain bike equipped with top-notch accessories, ready to face unknown challenges.

Climbing

As soon as we set off, it was a continuous winding uphill climb. The OCLV Carbon frame of Slash 9.9 is lightweight yet sturdy. Even when facing a steep climb, one can feel the stability and strength it conveys. Front fork RockShox Zeebon Conti Air Spring with precise damping adjustment. Perfectly absorbing every bump on the road, allowing me to concentrate on every step under my feet.

The SRAM XX1 AXS 12 speed transmission system responds quickly. With a gentle flick, the gears seamlessly switch between them, allowing me to find the right gear ratio on any slope and effortlessly conquer one height after another. As the altitude gradually increases, the air becomes fresher and the scenery before us becomes more magnificent.

Descending

While enjoying the pleasure of climbing, my eyes suddenly opened up. A winding downhill road stretches ahead, like a giant dragon, inviting me to release my inner wildness. The 29 inch Bontrager SE5 wheelset of Slash 9.9 is paired with Maxxis Minion DHF/DHR II EXO+tires. The grip is amazing, providing stable and direct handling feedback on both slippery rocks and soft soil. I raced all the way, and the Bontrager Line Pro Carbon braking system provided powerful braking force and delicate adjustment space. Allowing me to confidently navigate between curves on high-speed downhill slopes. Every sudden brake is just right, safe and enjoyable.

Of particular note is the rear gallbladder Fox Float DPX2 Performance EVOL of Slash 9.9. It seems to have magic, automatically adjusting its support according to the road conditions. Keeping the vehicle in a stable posture even when quickly passing through bumpy roads gives me an infinite sense of security. The Reverb Stepcast seat bar installed on the entire vehicle allows me to easily move up and down when I need to quickly adjust my riding position. Whether it’s jumping or skillful movements, it’s more effortless.

As the sun set, I completed today’s ride. Sweat soaked the back of the clothes, but the heart was filled with unprecedented satisfaction and joy.

Trek Slash 9.9 XX AXS T-Type Gen 6 VS Specialized Epic Hardtail Bike

The Specialized Epic Hardtail is a hard tail mountain bike characterized by lightweight and fast climbing. It also uses a carbon fiber frame, but at a more affordable price of only $2500. The carbon fiber structure of the Specialized Epic Hardtail makes the entire vehicle lighter. The lack of rear shock absorption design reduces the weight of the vehicle and reduces the speed increase loss caused by the absorption of kinetic energy by the rear shock absorption, thereby improving energy efficiency.

This car is equipped with SRAM Level T hydraulic disc brakes and SRAM NX Eagle 1 × 12 transmission system, providing a smooth and reliable shifting experience. Its 100mm front fork stroke and air spring maintain lightweight during descent. At the same time, it responds sensitively to bumps, allowing riders to easily handle various complex terrains. Although it may not be comparable to professional downhill bikes in terms of performance degradation, the Specialized Epic Hardtail’s performance in actual cycling is still commendable.

When comparing these two cars, it can be seen that the Trek Slash 9.9 XX AXS T-Type Gen 6 is more suitable for riders seeking all-around high performance, especially in complex terrains and long-distance cycling. The Specialized Epic Hardtail is more suitable for riders who prioritize lightweight, fast climbing, and have limited budgets.
