Learn More About the 2023 Rocky Mountain Vertex Jr 20
The 2023 Rocky Mountain Vertex Jr 20 is made for kids who want to get out on the trails and improve their mountain biking skills. This bike handles rough terrain without feeling like a heavy chore, thanks to a frame and parts designed with young riders in mind.
Frame
The Vertex Jr. 20 is built on a Rocky Mountain 6061 SL Alloy Frame. This frame strikes a good balance. It's light enough to keep the bike nimble but tough enough to take on off-road bumps and crashes. Its geometry is shaped to help kids feel in control and confident as they ride over different types of terrain.
Gears
Shifting gears is smooth and simple with the Sunrace drivetrain. It offers a range of options that make going uphill easier and zooming downhill more fun. Kids won't have to think twice about changing gears. This means more focus on the trail and less on the mechanics.
Suspension
The suspension matters when the ground gets rough. The Suntour XCM JR Air fork has 80mm of travel and uses an air spring that can be tuned to a rider's weight and preference. That means bumps don't get the best of the ride, helping kids stay comfortable and maintain good control.
Wheels
The Rocky Mountain JR25 Tubeless ready wheelset fits this bike perfectly. Built tough and light, they come with Shimano TX505 hubs that keep the spin smooth. Going tubeless means kids can run lower tire pressure, boosting grip and making the ride feel easier and steadier on rocky or loose trails.
Brakes
You'll also find a set of Shimano Deore 2-piston brakes. These deliver consistent, reliable control that lets young riders confidently slow down or stop, no matter the trail condition. They're also built for durability and don't need a lot of fuss to keep them running well.
Tires
The tires are Kenda Amrak 20 x 2.4, offering a great mix of traction and cushioning. With that width, the tires soak up bumps while still rolling efficiently on the trail. This helps kids hold their line and enjoy their ride without slipping or sliding unexpectedly.
Comfort
Comfort counts, especially on longer rides. The Rocky Mountain pivotal kids' saddle is shaped specifically for young riders, giving them support without causing hotspots or discomfort. It's easier to focus on riding when your seat isn't a distraction.
This bike gives young riders a solid, fun, and reliable setup that grows with them as they build confidence and skill on the trails.
