Shimano Tiagra CN-4601 10 Speed Chain

The Shimano Tiagra CH-4601 chain is compatible with the new series of Shimano directional (asymmetrical) road chains. Asymmetrical plates ease shifting on the most difficult shifts: up the cassette in the rear and shifting up from the small ring into the large chainring. This chain is designed to shift quickly and quietly on Shimano Tiagra 4600, 105 5700, Ultegra 6700 and Dura-Ace 7900 cassettes/chainrings. Perforated plates leave some of the weight behind without detracting from shift performance or durability.
