As above, usually use mine on a steel freehub, but making the SS a bit pimpy and light weight... and a change of wheels means I could go alu...
Any issues with digging in or OK?
never a problem with mine (Groove Armada)

Cheers for that, sounds promising.
I get more trouble with cassettes digging in (even the ones with carriers for the bigger toothed sprockets) than sprockets like the Groove Armada.
Never have any problems. Have use Gusset Double SIx cogs as they are about the widest out there at 7mm.
Used them for years on a fixed gear splined hub which I run brakeless so a fair amount of back and forward forces. No marks at all of alu body.
Wide base is fine on alloy freehubs, even for my lardy arse
great feedback, thanks folks. I'll stick the steel freehub on the heavy transport bike 🙂
I run two Surley sprockets next to each other on a hope hub with no issues. Spaced either side, I get the choice of two gears.
