THE NEXT EVOLUTION OF JUNIOR MOUNTAIN BIKING
The Siskiu D24 is the next evolution of dual-suspension bikes for children who have outgrown riding their hardtails. If your child is riding hard and needs a bike to keep up with them, let us introduce the D24.
READY FOR ANYTHING - The D24's lightweight dual-suspension alloy frame is ready for any challenge on the trail. Airsprung fork and shock are completely tuneable for your kid's weight and riding. The tuneability also allows the bike to be adjusted as your child grows.
AGILE AND ABLE - The D24s geometry mimics its older siblings and promotes agile riding. Agility also leads to easier riding for smaller kids as they can maneuver the bike with less effort. This allows them to build their skills and ride better.
STABLE AT SPEED - Thanks to the subtle 120mm of suspension front and rear, the D24 is stable even over the roughest terrain. Stability at speed encourages riders to push their boundaries and skills in safety.
LIGHTWEIGHT ALLOY FRAME - Even though the frame is super light, it has been built to take the abuse of challenging trails. Rocks and roots have no chance against our ALX Frame.
RELIABLE - Polygon understands that riders want to spend more time on the trails and less time fixing their bikes. Polygon has gone out of their way to spec the D24 with robust components from SR Suntour, Microshift, and 32 spoke wheels.
CUSTOM TUNED SUSPENSION - Polygon understands D24x riders have big dreams, even though they are still smaller in stature. They have custom-tuned Suntour rear shock and forks with a softer tune to inspire confidence as your child pushes their limits.
HYDRAULIC DISC BRAKES - Promax hydro disc brakes provide minimal fuss, supreme modulation and tonnes of power in those moments the rider may need to pull up quickly and get out of a sticky situation.
MICROSHIFT ACOLYTE 1X GEAR SYSTEM - Microshift's one by eight drivetrain provides smooth shifting, robust reliability and a range of gears to get your child up any mountain.
WIDE RANGE CASSETTE AND TRIGGER SHIFTER - To work well with one gear upfront and provide your child with the best gear for any situation, the Microshift wide range cassette will always have the correct gear for any obstacle.
ADJUSTABLE AIR-SPRUNG SUSPENSION - Air-sprung suspension is adjustable to your child's weight so as they grow the bike will perform perfectly throughout the years. Thanks to the 15mm thru-axle and 32mm stanchions, the Suntour fork's stiffness will hold your child's chosen line and change direction accurately.
BIG TIRES FOR BIG TRACTION - The bigger 2.4-inch tires add more grip, more comfort and extra confidence through the rough stuff. A high-volume tire will also require less pressure, so your child won't be bouncing all over the trail.
