Ok, it's obvious that the spacing on 8 and 9 speed cogs are different. Are the acutal cogs any thinner on 9 spd vs 8 spd.

I'm curious because I'm contemplating a switch to SRAM. The 1:1 actuation ratio combined with the integrated pully (eliminating the rear cable loop) is supposed to pick up for all the slop thats notorious in Shimano 9 spd equipment.

However, I am a bender of rear cassettes. If 9 speed is thinner, I don't want anything to do with it.

Can someone definitely answer this question??? Are the 8 and 9 speed cogs essentially interchangeable using different spacers ?????

Yes 9spd cogs are thinner

I dont have the meausrements handy but they are thinner. And since there aren't any loose cog cassettes anymore it wouldnt matter too much if they were interchangable or not.
