Box One Prime 9 Speed DLC Bike Chain - Black - 126 Links}, Black
  • £50.00

Box One Prime 9 Speed DLC ChainThis 9 speed MTB chain features a hardened alloy steel construction, which gives it reliable operation on every off-road ride. Classed as Box's best performing chain, this model is also equipped with a durable dual-coating with nickel-plating for protection against corrosion. This makes it suitable for use in all-weather conditions, while its durable hardened solid pins give it extra durability on the most demanding of trails.The Box One chain is protected by our dual-coating. We start with Nickel plating which aids in corrosion resistance and then top it off with the "Diamond-Like Carbon" layer. The DLC is as fancy as it sounds; a synthetic diamond nano-coating that turns up the volume on hardness, wear-resistance, and slickness. All Prime 9 chains have chamfered shifting edges, solid plates and solid pins to safeguard durability. Our unique inner link spacing is engineered to grab those modern wide/narrow chainrings. We chose to modernize the 9-speed platform due to the chain's spirited reputation.FAQ:Is the Box One Prime 9 Chain compatible with other 9 speed drivetrains? Yes, All Box prime 9 chains have standard external geometry that will work with most existing 9 speed drivetrains.Is the Box One Prime 9 Chain Compatible with any wide narrow chainring?
