Reactor 275 Carbon Frame

This MTB speed measure favors setups that roll efficiently without sacrificing too much traction. It trends this way because of a very light build, a lighter-feeling build that helps when you're pedaling for speed, typical trail-width tires, and a basic drivetrain spec that prioritizes practicality over outright performance. Taken together, those choices reduce wasted energy when you're trying to go fast.

Climb score: 8.6/10. Within Mountain bikes, it lands near the top. When it gets steep, the gearing feels very easy. In numbers, the low gear is roughly 16.9 gear inches. On the ‘easier low gear’ scale, it sits around ~77% versus similar bikes. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. This kind of low gear helps you stay smooth on long or steep climbs. Build kits can differ by size and spec level, and not every detail is published by every brand, so use this as a practical guideline.

Overall suspension support: 8/10 (“High-impact ready”). This level is aimed at repeated impacts and rougher terrain, keeping the bike more settled at speed. Full suspension means both ends can absorb impacts, helping the wheels track rough ground more consistently. Travel means the suspension’s movement range over a bump. On this bike it’s about 155 mm up front. Generally, more travel helps when hits get bigger or come faster. It’s designed to stay composed when impacts come quickly one after another, especially at higher speeds.

Sporty fit - a performance-leaning position that encourages speed. This is mainly because bars are around 89 mm lower than the saddle, which is a large drop, and the forward stretch measures around 635 mm (very long). Expect a lean angle around 35 degrees.

What drives the fit flexibility here: A modular front-end gives more freedom to change stem length or bar width, and Because cables are routed internally, adjustments may take more work. That is why we tag it Moderately Adjustable.

Comfort comes out to 7.4/10, which usually translates to a easygoing over rough patches ride. Within Trail, Firm basically means 'less plush than the softest builds' even though the ride still feels easygoing over rough patches. The posture is forward, attacking (posture 8/10, torso ~35°), which loads the front wheel, which feels great for control but a bit more direct through the bars.

This is the kind of deal people usually notice quickly. 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). Based on the spec estimate, it comes in about 22% under the typical level for similar builds. In its peer group, it tends to be better-priced than many, beating about 75% of listings. Quick reference: €3.120 listed versus about €3.980 for a comparable build. Some manufacturer details aren’t fully published, so use this as a helpful direction rather than a final verdict. Bottom line: you’re getting a lot of bike for the money compared with typical options.

This bike is built for everyday trails with a mix of roots, rocks, and turns. It has about 140 mm of suspension travel (how much it absorbs bumps), which works well for everyday trails. Suspension type (Full) fits this kind of terrain.
