Frame: 4130 Chromoly for Superior Strength

The L100 utilizes a full 4130 Chromoly frame, a material renowned for its exceptional strength-to-weight ratio. Chromoly steel, containing chromium and molybdenum, is known for its resilience and ability to withstand high-impact forces. This makes it an ideal choice for BMX bikes that endure significant stress from jumps and landings. The L100’s Chromoly frame ensures durability and longevity, allowing riders to confidently push their limits without worrying about frame failure.

Drivetrain: Efficient Power Transfer

The L100’s drivetrain is designed for efficient power transfer and smooth operation. It features 175mm two-piece tubular Chromoly hollow spindle cranks, which are both lightweight and strong. The hollow spindle design reduces weight while maintaining stiffness, ensuring optimal power transfer from the rider to the rear wheel. The 25T aluminum chainring provides a good balance of speed and torque, suitable for various riding styles. The mid-sealed bearing bottom bracket ensures smooth and efficient rotation, minimizing friction and maximizing power output.

Wheels: Stability and Grip

The L100 rolls on 20-inch wheels with wide aluminum double-wall 36H rims. These rims are built for strength and durability, capable of withstanding the impacts of freestyle riding. The double-wall construction adds an extra layer of reinforcement, reducing the risk of dents and damage. The 2.4-inch wide tires provide excellent grip and stability, allowing riders to maintain control even on challenging terrain. The 3/8-inch female axle front hub and 9T cog sealed bearing cassette rear hub ensure smooth and reliable wheel rotation.
