Shame to move away from a new found 'standard' 10 speed chain width.
The chain width has been reported to be 5.5mm. No word on cog thickness or spacing, but using past values for minimum clearance, the cogs can't be any thicker than Shimano's 1.6mm. I'm predicting something very close to 1.5mm cog thickness, with 2.2mm spacers, for a c-c spacing around 3.7mm. Cog thickness might be a bit more, if the space between the largest cog and spokes is reduced a bit.
Even the crank/chainrings will be 11 speed, but no word yet on whether the difference will be a change to the tooth thickness, or just a minor chainring spacing change. As it stands now, there is about .33mm clearance between inner sideplates and chainring teeth. If that clearance can't be reduced a bit, then the chainrings may indeed be 11 speed specific. Time will tell.
