• 150mm travel: A single-crown bike with the travel you need for the steepest and rockiest trails.
• B.O.O.M. BOX : Pack everything you need under the solid flap in your down tube.
• Size-dependent geometry: The chainstay lengths of the Sentinel increase with the frame size and the seat angle becomes steeper. This gives every rider – regardless of size – the same balanced geometry and perfect riding characteristics.
• Size-dependent frame stiffness: Larger riders cause higher loads. That’s why we adjust the stiffness for each frame size to ensure that every rider gets the same ride quality.
• Main Pivot Mud Guard:A pre-installed guard protects the main pivot and increases the service life of the bearings.

If you’re between two frame sizes, we recommend that you test both options. As a guide, you can compare the reach and stack values with your current bike or other well-known bikes that you feel comfortable on. If a test drive is not possible, you can also use the following tips as a guide:

1. A larger frame gives you more stability and confidence. You also have more freedom of movement on the bike, with less influence on the balance. With a larger frame, you have a slightly longer wheelbase, which provides additional safety and stability. You therefore need to use your body more and have a slightly more active riding style to control the bike. Smaller bikes are more agile and react more quickly to the rider’s input.
2. Even if you are the same height, everyone looks different. If you have a relatively short torso and long legs, we would recommend a smaller frame size. If you have a long torso and long arms, you should opt for a larger frame.
