Most riders wait until the teeth look like \"shark fins\" to replace them, but swapping them once a season will keep your drivetrain feeling elite and prevent premature chain wear. It’s the cheapest way to buy back that premium Shimano feel.\u003c\/p\u003e\n\u003cp data-path-to-node=\"10\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"10\"\u003eCrisp Indexing.
