Sender CFR 29 Underdog

For mountain riding, it captures how the bike carries speed when you're pushing the pedals on less technical surfaces. This means it trades speed for comfort, durability, or practicality. The biggest contributors are a heavier build, typical trail-width tires, and a solid drivetrain that supports efficient riding. On smoother terrain, the tire setup is biased toward rolling speed on firm ground.

On steep roads, it comes in at 3.0/10. Within Mountain bikes, it lands below average. For hill work, the easiest gear is very tall. In numbers, the low gear is roughly 34.6 gear inches. Most comparable bikes have an easier low gear; this is easier than only about ~4% of them. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. Weight is around 17.4 kg — on steep, slow climbs that extra mass becomes more noticeable. Expect more grinding on climbs than easy spinning. 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.

Suspension: 10/10, classed as “Extreme rough-terrain ready”. That’s built for big impacts and very rough terrain, where keeping wheels tracking matters most. Full suspension means both ends can absorb impacts, helping the wheels track rough ground more consistently. This is maximum composure territory: traction and control are the goal. Travel is how far the suspension can move when it hits a bump — here it’s about 203 mm up front and 200 mm at the rear. As a rule of thumb, more travel gives more headroom for bigger impacts.

Sporty fit - you'll lean forward more and feel ready to push the pace. That's driven by bar height comes out ~85 mm below the saddle (large), with about 654 mm of forward reach - a extreme stretch. Expect a lean angle around 34 degrees.

That is why we tag it Moderately Adjustable. What affects adjustability on this bike: The cockpit is modular (separate stem and handlebar), so it is easier to adjust or swap fit parts; A more service-friendly routing setup makes changes easier. This mainly reflects how easy it is to adjust or swap key fit parts over time.

Comfort comes out to 8.8/10, which usually translates to a plush ride. That’s the reason it lands as Comfortable. The posture is forward, attacking (posture 7/10, torso ~34°), which loads the front wheel, which feels great for control but a bit more direct through the bars.

Compared to similar bikes, this is priced very competitively. The value score is 1–10. Higher means better value for money; lower means the price is high for what you get. 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 14% under the typical level for similar builds. In its peer group, it tends to be better-priced than many, beating about 79% of listings. To anchor it: price €4.724 versus an estimated €5.465 for a similar build. Overall, it looks like a great-value pick in its category.

This bike is made for very rough terrain, big hits, and bike-park riding. It has about 200 mm of suspension travel (how much it absorbs bumps), which is useful for big hits and steeper descents. Suspension type (Full) fits this kind of terrain.
