KMC Z-Narrow High-Performance 7-Speed Drive Chain (114 Links)

Description

Smooth Power Delivery & Factory Cruiser Performance

Reclaiming the smooth, quiet glide of your Fission Cycles cruiser starts with a fresh, factory-spec chain. The KMC Z-Narrow is the official OEM replacement chain chosen specifically for the SO/ST 500 Cruiser line. Built using high-tensile steel alloys and reinforced rivet pins, this chain is engineered to withstand the continuous pulling force of your 500W motor without stretching, skipping, or slipping off the gears.

Despite the “Narrow” factory stamp on the outer links, this profile is the designated industry-standard width for 7-speed and 8-speed systems. It provides the exact side-plate clearance needed to shift quietly across your rear Shimano Tourney freewheel without grinding or getting hung up between the cogs.

Pre-Sized for Cruiser Frames: Cruisers feature elongated chainstays to give you that comfortable, laid-back riding position. This chain comes in a 114-link configuration, providing the extra physical reach required to stretch cleanly from your front ProWheel crankset all the way to the rear axle dropouts without over-tensioning your rear derailleur.

Technical Highlights

• Genuine SO/ST 500 OEM Fit: Direct drop-in replacement that perfectly matches the factory gear tooth profile of your cruiser’s Shimano Tourney SIS Index 7-speed system.

• High-Torque Durability: Built with a rigid inner-plate structure that resists twisting and lateral stress under electric pedal assist and throttle acceleration.

• Smooth Shifting Chamfers: Smoothly slides from gear to gear, eliminating annoying chain slap and ensuring immediate, quiet engagement.
