About this item

• Application: Hollowing technology can easily reduce weight, make riding lighter. It is suitable for mountain bikes, station wagons, folding bikes. It is also one of the best choices for gifts.
• Safe Efficient Design: Intensity is more secure, apply for long time cycling. Oval chainwheel superiority, increased frequency, and easier middle gear planning.
• Smooth: The flywheel is made of high tensile steel plate, tempering hardening treatment, multi layer plating, which can obtain a smooth and easy shifting experience even under load.
• : The crank is made of high strength aluminum alloy, suitable for various harsh riding environments. Anticorrosion, good heat resistance, and long service life.
• Oval Chainring Advantage: Designed to provide varying mechanical advantages at different points in the pedal stroke. This effectively changes the gear ratio at different angles of rotation for an ergonomic feel.
