Key Features:

• Easy Adjustability: With 29 size adjustments ranging from 90mm to 160mm in 2.5mm increments, you can easily adapt the crank size to fit children aged 3 to 13 years.
• Lightweight Design: Weighing in at only 507g (1lb 1.85oz), this crankset is designed for optimal performance without the added bulk.
• High-Quality Material: Crafted from durable 7075-T6 aluminum, ensuring longevity and resilience during all cycling activities.
• Compatibility: The crankset is Raycelite compatible and works seamlessly with Ultralite Spider and Square Taper Crank systems, providing versatile options for your cycling needs.

Additional Information:

Ensure a safe and optimal cycling experience by adhering to the weight limit of 125lbs. Proper installation is crucial; make sure all fasteners are securely tightened to prevent damage to the crank arms. Remember, the set screws located in the lockrings serve as a locking feature—these need to be loosened before removal and tightened after securing the lockring in place.

Note: The crankset does not include a spider, and the Rennen Smart Sprint is an excellent addition for those looking to validate their testing.
