Your wide narrow chainring has an even number of teeth.  You run whatever cog 
size you like, odd or even, still works

And especially nifty coming from White as most wide/narrow on the market 
are black and work with a limited number of cranks.  Now White crank fans 
can join the party.

Re: [RBW] Re: New White Industries ring design!

2015-03-06 Thread Bill Lindsay
Let me show you :) http://lmgtfy.com/?q=wide+narrow+chainringl=1

It's a chainring where every other tooth is wide and every other tooth is 
narrow, fitting the wide and narrow gaps in your chain.  The result is the 
chain fits more solidly on the chainring and is less likely to jump off. 
 It's the common setup for a 1x drivetrain.  By running a wide narrow ring 
you can avoid running a chainwatcher or a vestigial front derailer to keep 
the chain on.  You can't run wide/narrow rings with multiple chainrings 
because if you shifted from one to the other and didn't hit the right kind 
of tooth, the chain would skate on the top, or fall off, or get a narrow 
gap wedged onto a wide tooth.

The teeth alternate between narrow and wide. It serves to keep the chain on
the chainring without any other pieces of hardware (jump stops, etc)--very
effectively, in my experience.
