Shimano CN-4601 Tiagra 10 Speed Chain 116 Links

Super Narrow Hyperglide (HG) series 10-speed compatible directional chain, recommended for Tiagra drivetrains
Chain uses a directional design with specifically shaped inner and outer plates to optimise shifting over the chainset and cassette
Outer plate design has been developed to reduce the chance of chain suck
The inner plate has been developed for better contact with gears providing smoother shifting under high load, giving efficient pedalling, increased rigidity, and near silent running
For use with double chainset only
5.88 mm chain width, optimised for 10-speed Super Narrow HG drivetrains
Corrosion-resistant grey finish on outer plates
