AIR 9 2-STAR SRAM SX EAGLE

On an MTB, the speed score centers on rolling efficiency when you're pedaling, especially on easier terrain. Compared with more speed-first builds, this build is shaped by a light setup, a lighter-feeling build that helps when you're pedaling for speed, typical trail-width tires, and a more budget-friendly drivetrain that focuses on value.

Climbing rating: 9.8/10. Within Mountain bikes, this comes out near the top. On climbs, the lowest gear feels very easy. In numbers, the low gear is roughly 16.9 gear inches. In its peer group, it lands around the easier ~77% for low-gear climbing. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. At about 11.3 kg, it’s in a normal range, so gearing matters more than weight swings here. You’ll be able to keep a steady spin even when it gets steep. Specs can vary by size and build, and some manufacturer details aren’t always published, so treat this as a strong guide rather than a guarantee.

Suspension sits at 6/10, in “Confident trail control”. That typically means noticeably better bump absorption and more consistent tracking on rougher sections. The fork does the smoothing; the rear stays straightforward and efficient. This level helps keep traction when the surface is uneven and choppy. This level usually brings more reliable wheel tracking on rough patches and repeated hits.

Balanced fit - a neutral road posture that suits most riders. Mostly geometry-based, with a small category-based estimate.

In Mountain, Overall, it falls into Adjustable. What affects adjustability on this bike: Standard cockpit parts make it simpler to fine-tune your position over time, Less routing complexity makes swaps and adjustments more practical. At the same time, A dropper makes it easier to shift between climbing and descending positions.

Comfort comes out to 6.6/10, which usually translates to a comfortable ride. So it’s tagged Firm overall. The posture is neutral (posture 5/10), which gives a steady, predictable feel without pushing you too far forward.

This looks like strong value, even if it’s not the absolute cheapest listing. Value is scored 1–10: higher is better value, lower means you’re paying more than similar bikes. Uses MSRP as a baseline; real-world prices can be lower (discounts can change the value). On the spec estimate, the price is close to what we’d expect for a comparable build. Among comparable bikes, it sits around the middle on price (cheaper than about 61% of listings). To anchor it: price €2.199 versus an estimated €2.231 for a similar build. Put simply: it’s competitively priced for what you get.

This bike is best for smoother trails where speed and efficiency matter. It has about 120 mm of suspension travel (how much it absorbs bumps), which suits smoother trails. It’s listed as Trail, but the parts point more toward Flow Trails.
