    金属製フレームがお好きな方もご安心を。Stumpjumper Comp Alloyは、最先端のアルミ合金フレームを採用しています。左右非対称のデザイン、新しいジオメトリー、改良したサスペンションキネマティクス(リンク設計)、コストパフォーマンスに優れたスペックを備え、いつでもトレイルに繰り出すことができます。

    • トレイルの新基準
      Stumpjumperの設計を見直すにあたり、ある大きな目標を掲げました。その目標とは、耐久性、勢いを保ったままコーナーを曲がれる高い剛性、誰でもしっくりくるジオメトリーを犠牲にしない範囲での最軽量でありながら、私たちが熟知している最高のサスペンションキネマティクスを持ち合わせること。そんな欲張りなバイクが、新しいStumpjumperです。

    • トレイルを平らに感じさせる130mm リアトラベル
      トラベル量がどれだけあろうと、適切なサスペンションキネマティクス(リンク設計)を採用しなければ意味がありません。そのため、新しいStumpjumperでは最先端の技術を駆使して設計しました。前作Stumpjumperのサスペンションキネマティクスから得た知見と、数えきれないほどのフィールドテストおよびサスペンションラボでの研究をもとに、新型ではライダーが望む走破性および効率的でキビキビした走りと、大幅なペダリング効率の改善を両立しました。新しいStumpjumperは、スイスイと上れながらも、下りでは完璧なコントロール性能を発揮します。※S1サイズのリアトラベルは、125mmになります。

    • 先進的なジオメトリー
      新しいStumpjumperのS-Sizingジオメトリーは、上りから下りまでバランスよく楽しむために最適なジオメトリー。リーチが長く、低重心、ヘッドアングルは寝かせ気味でシートアングルは立たせ気味。そして短めのオフセットのフォークと来れば、すばらしい走りは保証されたようなもの。Flip Chipならジオメトリをより細かく調整でき、あなたのStumpjumperはどこでも走りたい場所にぴったり合った完璧な走りを約束します。

    • RIDER-FIRST ENGINEERED™ — Rider-First Engineered™ frames use a size-specific approach to ride characteristics that ensures benchmark handling and flawless performance, regardless of frame or rider size. Whether you’re a jump-happy grom riding an S1, or a DH-fiend giant in need of the lengthy S6, you’ll experience the same ride traits – rail-sharp cornering and balanced front and rear stiffness – at the lightest-possible weight, And by light, we mean real light: 2,250 grams (S-Works, S-3 size, with rear shock).

    Great bike, but needs some upgrades

    I have really enjoyed my 2021 Stumpjumper Comp Alloy, it was a huge upgrade over my Norco Fluid HT2. It handles all the blue/black trail riding I do and makes me want to ride as much as possible. However, I have already had a few issues with the bike after 2 seasons. 1) The rear shock had to be rebuilt after the first season. 2) the rear hub had to be replaced after the 2nd season. It is a good value bike, but be prepared to upgrade the rear hub if you ride a lot.

    Heck ya, so fun!

    This bike is awesome! I fitted it with some cool upgrades and rode the heck out of it last season. I have ZERO complaints with my new Stumpjumper! It rides smooth and handles excellent, so fun!

    No confidence in this one

    I own multiple bikes and this one is by far the most unstable. The butcher front tire lets go without warning unlike the dhfs and agassi I have on my other bikes. I have tried multiple pressures with no luck. The SRAM brakes take a longer pull to grab than shimano brakes. The suspension is great but too many front tire wash outs and too hard to stop.

    Nailed it

    This bike has been great for me. At 5'11 S4 is perfect. Feels planted and confident at speed and lively and flick-able everywhere else. Comfortable and easy to climb with. Get the bottle cage and Specialed tool as well.

    OMG! All you have to do is think it.

    I have about 1,500+ miles on mine. It has saved my bacon so many times. In situations I knew were not ideal I would just think it and the bike would say give me more. 27.5 for ever!

    Love my Bike

    Got my hands on a new S1 and it is awesome. I love taking it DH at Keystone Bike Park while also using it to do some nice uphill and as a beginner it's a better bike than I'll ever be a rider that's for sure!

    I glad I bought this bike!

    My first full suspension bike. I'm 6'2'' riding a s5. Bike is glued to the trail. Pedals great. Turns awesome feels super stable turning but still nimble. I was nervous about going to 29ers from 27.5 on my last bike. Well I was nervous for nothing . I used sizing guide and sized up one for a more stable ride I feel it was a great decision. The welds are pretty nicely smooth out. It's great looking bike with modern geo tons of stand over.
