Do I need a new hub (body) when upgrading from 8 speed cassette to 10?

Hello folks,
I am upgrading my CAAD 8 with 2300 8 speed group to a 10 speed 105 one. The bike has cheap heavy but bullet proof Maddux R3 wheels and Formula RB-51/52 hubs. So, can I just put 10 speed cassette instead of an 8 speed one? I need a spacer, 1 mm (or is it 2mm?) I guess. But will the hub body sustain narrower 10 speed cassette's cogs? I tried researching the topic but got confusing results. Some people say that eventually narrower cogs will wear out the hub body. I am not looking to upgrade wheels and hubs as of now. Later on I ll just buy a better set, but right now I am good with what I have.
Thanks a bunch

I think Cannondale is selling 10-speed versions of the bike with the same hubs, so. . . probably fine.

Real experts will be here soon.

Search the forum for "freehub".... lots of discussion directly related to your question. The answer is "it depends." You will have to pull of your cogset and measure your freehub to see if it is long enough. The threads provide the length for the free hub that is long enough.

You should be OK using a spacer. 10 speed cassettes are shorter.

If Shimano compatible, you should be fine as 8 speed freehub IS and 8/9/10 speed freehub already. Careful with certain Dura Ace models though.

If a Campagnolo setup, you have some work to do.

2. I like anyone will comment in other areas.
3. I do not own the preexisting concepts of DISH and ERD.
4. I will provide information as I always have to others that I believe will help them protect themselves from unscrupulous mechanics.

Yes, the 10-speed cassette will fit just fine and the 1 mm spacer it requires comes with it.
