SS chain and cog

Hi...I'm back with yet more single speed questions...

I've bought a ss/fixie crank described as 1/2 x 1/8 (I don't actually understand what that means). I'm looking to get a wide base ss sproket (the ones that came with my ss conversion kit are so thin they'll cut through my freehub like a kinfe through butter!). However I don't know what to get as I assume it has to be compatible with the crank teeth so I can fit an appropiate chain (which I also need to know what would be compatible). I've seen on ones wide based sprokets which are the sought of thing I'm after...but the description says they're suitable for a 9 speed assuming you can't used a thicker chain - so not compatible with my crank?

Help?!?! SO confused!!

If you could bestow me with your wisdom I would most appreciate it

    1/2" is the pitch which is the same for all bikes and 1/8" refers to the width of thechain roller / sprocket which is the common size for track, singlespeed and BMX. You'll need to run a 1/8" chain because of the thicker chainring but could use a thinner 3/32" or 9 speed sprocket on the rear, it'll just be a little 'noisier' and may wear slightly quicker but functionally will work OK
    Make mine an Italian, with Campagnolo on the side..
  • Thanks monty dog, you've been a great help once again

    Thats great, I was having difficulty finding 1/8th cogs with wide bases, but I know what to do know, cheers
