12/13 tooth drivers

Today we received some samples for our 12/13 tooth one piece drivers. why would anyone want a 12 or 13 tooth driver you ask?? simple. Many frames are still being made with brakes mounted on the chainstays, therefore the smallest you can (usually) go gear wise is 36/13. Considering you cant go any lower, and you probably wont be going up, why not have a solid one piece driver to make your hub a little better (without adding on any weight). One piece is better than 4.
The 10t driver is on the way, so we figured we might as well have one piece drivers all the way up to 13. the 12t is on my bike now and it feels awesome.

PLEASE NOTE: the 12/13t drivers are not available yet. These are just samples for us to test before production.
