Thunderflash FRAME

On trails, this rating is about rolling speed and momentum, not suspension feel or handling sharpness. In day-to-day use, it prioritizes confidence and everyday riding over outright pace. Key drivers include typical trail-width tires and a basic drivetrain spec that prioritizes practicality over outright performance.

Climb score: 8.6/10. Within Mountain bikes, it sits near the top. When it gets steep, the gearing feels very easy. The easiest gear works out to about 16.9 gear inches. In its peer group, it lands around the easier ~77% for low-gear climbing. “Gear inches” sounds nerdy, but it’s just a quick way to describe how easy your lowest gear is to turn uphill. Lower usually means easier. This kind of low gear helps you stay smooth on long or steep climbs. Different builds can shift the feel a bit, and some manufacturer specs aren’t always publicly listed, so consider this a helpful direction.

Suspension sits at 8/10, in “High-impact ready”. It’s designed to stay composed through rough sections and repeated hits. Suspension at both ends helps keep wheel tracking steadier when the surface gets rough. 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. It feels this way because you get a moderate drop: roughly 69 mm from saddle to bar, plus about 649 mm of stretch forward (extreme). You'll likely be near 31 degrees of lean.

In Mountain, That is why we tag it Moderately Adjustable. Fit flexibility summary: Standard cockpit parts make it simpler to fine-tune your position over time - A more service-friendly routing setup makes changes easier.

This scores 6.7/10 for comfort, so it feels nicely smooth out on the road. So it’s tagged Race-Stiff 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. Suspension type (Full) fits this kind of terrain.
