Despite being a trail-focused bike with 150mm of rear travel, the Sentinel surprised me with its climbing capabilities. The Horst Link suspension system efficiently mitigates pedal bob, allowing me to maintain traction and power on steep ascents. The seated position feels comfortable and efficient, thanks to the steep seat tube angle. I found myself easily conquering technical climbs that would have been more challenging on other bikes.

The 160mm fork complements the rear travel perfectly, providing a plush and controlled ride when tackling rough descents and drops. I felt like I could charge through rock gardens and take on berms with ease.

Downhill Dominance: Conquering Descents 

When it comes to downhill performance, the V3 truly shines. Its advanced suspension system and stable frame geometry ensure a smooth and controlled descent, allowing you to tackle even the most challenging trails.
