Re:
M737 was 8 speed only, However I'm sure you could use it as a 7 speed cassette on a freehub designed for 7 speed (ie Deore XT FH-M730) if that was your intention as the cog spacing is the same, and hence the need for a wider freehub to accommodate the extra cog on an 8 speed system. It only changed at 9 speed with narrower spacing to fit 9 cogs onto an 8 speed freehub....

Re:
This is the confusion ! its an m737 as its printed on it and belive it or not i did manage to count the cogs and there are 7 :roll:
The wheel it came off had a 7 speed lx hub so i wondered if they actually made a 7 speed M737 or if someone had somehow left a cog off so it could be fitted on the shorter freehub ?

Re:
I'd be inclined to say they've left a cog out mate as that confirms what I was saying in my first post, Might be worth checking what cogs you have by counting the number of teeth on each and then checking it against something like Shimano tech docs to find which one is missing if need, likewise if you check something like Mombat it should confirm that the M737 was 'officially' only sold as 8 speed, however what the lbs/rider does is another matter.....

10spd fits on 8spd width hubs too btw.
If your mystery cassette has an aluminium carrier, its the 8spd cassette with something missing as already pointed out.
It may have had a small spacer added as it would have flopped about on the cassette body like a goodun.

Re: Re:
Meh!
I would say given I was trying to give constructive advice based on the situation Paul has, there is not enough of a difference to not be able to put a 8 speed cassette reduced to seven cogs on a seven speed freehub. I would say you'd be in the ballpark of 1.4mm difference between the two in overall width at most, Which could easily be taken up with a spacer if need, but I doubt this would even be the case as taking it up with the lock ring would most probably suffice, After all were not discussing the possibility..... He has it fitted already.
Add to this the vast number of people using DX & XT 7 speed thumbies 'with the hidden click' (which really isn't hidden as we all know it's there) with no issue on a 8 speed setup (myself included) again would confirm the spacing is close enough otherwise it wouldn't work and speaking personally I have no shifting issues. So ok, as a technicality they are not identical (one shall be more choice with his words in future) but justifiably close enough to work and for someone/lbs to go down this route if they wanted a lightweight 7 speed cassette on an alloy carrier, In which case it does offer reasonable explanation to the OP's question, especially given there is no such thing as an M737 7 speed variant...... To my knowledge anyway!
