42 anyone?

This might be the ticket for those who don't want to run a front derailleur or spring for XX.

A very cool idea. I'm waiting for the wolf tooth version (made in USA ) to match my wolf tooth front ring. The wolf tooth won't require a spacer either. Both aren't even available for a month yet.

I've got a 42 on mine and it's great. They will sell a lot of these.
