Deore cassette on Tiagra derailleur
Amazon seems to sell an 11-34T "HG-50" Tiagra cassette. See here
. But if you look on Shimano's website, such a thing does not exist! Once I add to cart, I see that this is really a Deore cassette.
Can I use it on my Tiagra rear derailleur? I'm talking plug-and-play, no modifications to anything. The Shimano website says the maximum sprocket for the Tiagra is 27T but I'm confused about the whole Amazon thing. There seem to be a lot of positive comments. Or should I just get one of the real Tiagra options?
