ZTTO 9/10/27/30 Speed Bike Hollow Chain Mountain Cycling Bicycle Parts chain

Description

Suitable for 9-speed road bikes / mountain bikes. Missing links make the chain easier to install. The titanium nitride coating does not rust to provide wear resistant. The 116 link can be adjusted to suit your choice. Please be careful not to overuse. The chain elongation preventing structure reduces the friction against the box and the gear. Even on high loads with uphill loads, the chain does not travel on the gears and can ensure fast shifts at this time.
