BBB FlatLine 12-Speed Bicycle Chain (BCH 14)

The FlatLine model was designed as a chain for 12-speed drivetrains and a wide range of applications, from road cycling to off-road riding. The flat-top profile and stated compatibility with Road, Gravel and MTB groupsets make it easier to choose a single model for different drivetrain configurations, provided it is compatible with a 12-speed system. The use of hardened high-carbon steel is intended to improve wear resistance, which in practice translates into slower chain elongation when riding under increased loads and in dirty conditions.

The chain has 126 links and is 1590 mm long, providing sufficient allowance for adjustment to most popular frame sizes and cassette and crankset combinations. A Smartlink connector is included, simplifying installation and servicing, especially when the chain is frequently removed for cleaning. Its 5 mm width and 279 g weight position it as a typical solution for modern 12-speed drivetrains, with a silver nickel-plated finish.
