after deciding i may keep my P2 ss i will need a ss kit that is suitable to be used with hope pro 2 freehub bodies.

i was recommended the cusset double but you have to pay an extra £9 to choose your ring size.

i'd ideally like a 15 or 16t ring

any recommendations?

might be able to get you a gusset 14 t ring for about £5 or so

brand new as well

Some single speed conversions and kits can chew away at the soft freehub body of a pro2.

Pro II freehubs are made of cheese, mine is already a bit mangled - I've had it less than a month.

I used a Surley 18t Cog - they are larger at the bottom, around 3-4mm, this is supposted to stop damage to freehubs, but it's starting to mark mine already.  

Don't know what to suggest really, other than be prepared to replace your freehub quite often! I'm already looking into the price of a Pro II trials replacement.

the pro 2 freehub is aluminium so is fairly soft, therefore having one ring about 5/6 mm wide with all the pressure can damge the freehub by chewing into the ratchets on the freehub body

to be honest i dont think that one ss kit will be much better than the next at preventing damge, you can get a steel freehub for the pro 2 which is a sensble option in the long run but if thats not an option then keep the lockring tight and the chain at the right tension and that should help a bit

Yes look here which is an easy piece of kit to fit, no tools actually needed.

I use a pro2 9 speed hub on my DJ bike which is singlespeed, I'm running the gusset double six kit and using the actual cogs, I know its not going to last forever but it does a better job than the usual dmr kits which seriousley are not a good idea for the standard alloy freehub from a pro 2.

Spacers: If you just want to buy the cog you can use old cassette spacers by taking a cassette apart. You could also cut down your dmr spacers but you would have to get it perfectly right.

on one groove armada is the only cog id recommend using on a pro 2 ....

because i know it doesnt mark them.......

never used a gusset ...width doesnt always mean non marking .... poor tollerances make marking worse
