Higher-end chains aren't necessarily "stronger" in terms of breaking strength, but they feature nickel or titanium-nitride coatings to resist corrosion and reduce friction. Premium chains also often use hollow pins to shave weight without sacrificing integrity. 3. Sizing and Installation

Third-party brands like KMC often produce chains that are cross-compatible, but for the smoothest shifting performance, "replacing like-with-like" is the safest strategy. how to buy a bike chain

The most critical factor is the of your drivetrain. Modern cassettes range from 1 to 12 (and occasionally 13) gears. As the number of gears increases, the space between the cogs on your rear wheel decreases. To accommodate this, chains for higher speeds are made progressively narrower.
