This MTB speed measure favors setups that roll efficiently without sacrificing too much traction. On typical routes, it's tuned for reliability and control rather than maximum speed. The biggest contributors are typical trail-width tires and a high-end drivetrain that tends to feel crisp under load. On the road or trail, that typically means it feels quicker to get up to speed and simpler to keep it there.

On steep roads, it comes in at 9.3/10. Within Mountain bikes, it lands near the top. The easiest gear is very spin-friendly on hills. That lowest gear comes out around 16.2 gear inches. Compared with similar bikes, this low gear is easier than about ~92% of them. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. It’s set up so climbs feel controlled rather than a grind. Real-world feel depends on setup and size, and some details aren’t always listed, so this is best seen as a well-informed estimate.

For suspension control, it lands at 8/10. Category: “High-impact ready”. This level is aimed at repeated impacts and rougher terrain, keeping the bike more settled at speed. Suspension at both ends helps keep wheel tracking steadier when the surface gets rough. This is meant for rougher terrain where repeated impacts demand stable wheel tracking.

Sporty fit - a performance-leaning position that encourages speed. This is mainly because the bar sits about 69 mm below the saddle (a moderate drop), and you'll be stretched forward about 649 mm in total (extreme). Plan for roughly 31 degrees of lean.

In Mountain, Standard cockpit parts make it simpler to fine-tune your position over time, The front-end is easier to work on, supporting fit tweaks over time. Plus, Seatpost info looks fairly neutral, so most fit change comes from cockpit choices. Net result: Moderately Adjustable.

This scores 8.5/10 for comfort, so it feels very smooth out on the road. So it’s tagged Comfortable overall. The posture is forward, attacking (posture 8/10, torso ~31°), which loads the front wheel, which feels great for control but a bit more direct through the bars.

This setup suits steeper, rockier terrain and harder hits. It has about 165 mm of suspension travel (how much it absorbs bumps), which helps on rough, technical trails. The Full setup supports this riding style.
