Compatibility, 7401 Dura Ace with 7410, Advice Please

surfguy13 · Oct 30, 2021

I have been looking for a DA 12-21 cassette and found a new old stock hyperglide but it is a 7401 rather than 7410, 7410 being 95% of the group on my road bike. I just wanted to be 100% sure that a 7401 cassette was compatible with 7410? I'm pretty sure it is but....................?!

Many thanks

Check what cassette you have at the moment and see if it's hyperglide?

Yes, I've always used Hyperglide cassettes on the bike. The 7401 I've seen is also definitely Hyperglide and not Uniglide.

I think you have answered your own question

Aha! So as long as it's a Hyperglide it will be OK regardless?

All Shimano 8 speed cassettes are compatible with all Shimano 8 speed gear systems. So, yes!

Thank you @foz for confirming that and thanks also to @Midlife! Really appreciated.

If you want to double check look at the velobase website for shimano cassettes and the 7401 is listed near the bottom of the list.
