Hello chaps, I'm looking for a bit of advice if possible. I've just swapped a new free hub onto my Camino, and it seems slightly shorter than my old one. It's 11spd, as supplied by Alpkit, so should in theory work. There does appear to be a bit more overhang of the cassette (see pic). Is this still acceptable? I've torqued it down to 42nm and it seems ok, but it's always prudent to check with more knowledgeable types.
Any opinions much appreciated, thank you.
Could there have been a spacer installed that you didn't notice and should have removed?
Could it be a cassette with separate sprockets and one of them isn't quite seated right (check that they're all evenly spaced)?
Thanks chaps. No spacers left on, and all sprockets are seated as they should be.
There’s maybe only and extra millimetre or so of lip.
Check the above, the general rule was if you can get three full turns on the lock ring then torque it up it should be fine.
We’re not all “chaps” on here by the way!

Based on the cassette overhang, or have you compared the bare freehubs side by side?
Thanks very much. Apologies @wheelsonfire1, I meant no offence.
@frogstomp - when I compared them side by side the difference was just visible.
If you are concerned then spacers are available to go behind the cassette. From memory Sturmey Archer did some thin steel ones, I’ve probably got some, I’ll post you one if you think it’s required. If you can tighten the lock nut (3 turns) and there’s no movement in the sprockets you should be ok.
As for “chaps” it’s a bit like addressing emails as “gents”, a lot of organisations haven’t moved on and realised there are people of a different orientation. My daughter (in the police) and myself, (when in the Fire Service), have to/had to constantly correct. Boring I know to some, but just being polite to others.
Hope some of this helps!
Get it cleaned, you will be surprised how much difference that will make

That would make it worse wouldn't it?
@granny_ring you are quite correct and made me chuckle at my stupidity! If the problem is in front of me I’m far better! Honestly!
Seems unlikely but just double checking it’s not an 11sp road cassette on an 11sp Mtb freehub?
Does the smallest cog still engage on the freehub splines? If it does, it'll be fine. I've had a few that look like the photo and have been fine.
I was thinking the same as Swanny, unfortunately 11speed doesn't just mean one thing!
The other thing to be certain of is enough engagement of the lock ring - as others said 3 threads etc. If not you could damage the threads in the freehub.
Of all things I had to do some working out what was wrong on a mate's bike last year when the cassette wouldn't seat properly (was loose even when the lock ring was torqued). But using a spacer off a 10+11 speed hub pushed the cassette outwards too far - only got about 1 thread turn.
Finally found there were 2 different lengths of lock rings !! When used in combination of different cassette and freehub bodies the tolerances meant the longer lock ring bottomed out. And the shorter one didn't have enough engagement !
