I have just recently purchased a used set of wheels, and the rear is laced to a Tiagra FH-4400 hub. I am hoping to throw on a 10 speed cassette, but can't seem to find any info stating specifically that this will work (I have searched high and low, and am fairly sure that it will work, but would just like to be sure).

• The Shimano literature states that this is only for use with 9 speed cassettes, is this only because Tiagra didn't have any 10 speed components when the 4400 series was released?
• The previous owner had a 7 speed on it and the when I measured the spacer width it was 3mm, I was under the impression that it should be 4mm?
• The spoke protector was still on, does that make any difference when installing a wider cassette (it will be coming off one way or another)?
• So does any body know of any reason why I would face compatibility issues?

Sheldon Browns site seems to say that any 130mm hub will be compatible with any 8,9,or 10 speed, and I am inclined to believe that to be the case, but would like to double check before dropping any cash on new components.
Thanks

Your parts are compatible.

There were some 10-speed only-hubs, but all other modern Shimano-compatible hubs are 8-, 9-, and 10-speed compatible.

The 10-speed cassette should come with a 1mm spacer that goes behind the cassette; that's all you need to install it on a 8- and 9-speed hub.

I asked a similar question here not too long ago. The responses stated that an 8- or 9-sp Shimano (or Shimano compatible freehub) hub, be it a road hub or mtb hub, would be equally compatible with 8-, 9- and 10-sp Shimano cassettes. Also, the 10-sp cassette would require the use of the included spacer to allow the lockring to properly secure the cassette on the freehub.

Thank you both. That is what the information seemed to suggest, but I guess I was just thrown off by the 3mm spacer and needed to be reassured.
