Frequently Asked Questions

What fits Shimano Chainring 24T for FC-T521?

On this page we list cranksets this chainring fits. Each listing was matched on a specification we hold for both parts; anything we could not verify is omitted rather than assumed to fit.

Can I use a higher or lower speed chain with Shimano Chainring 24T for FC-T521?

No. Shimano Chainring 24T for FC-T521 is a 10-speed component and needs a 10-speed chain. Chains for different speed counts have different external widths and inner-plate profiles, which causes poor shifting or interference with the neighbouring sprockets.
