We all know that interbike is going crazy right now, and that a majority of the spiffy new schwag comes out at this time.

Our friends over at White Industries, the ENO guys, have produced a two-speed fixed cog. They have previously done this with a freewheel with some success and I have also seen some BMX variations of the concept.

My question to you guys is: What are your thoughts on this concept with regards to fixed? Mentally it seems ok to me to have the chainline a little off on your SS mtb, but the chainline is my obsession on my fixed gear. Especially for an item that is constantly rotating, typically under large forces.

What do you think?....
