Mega AM (for enduro) and Mega TR (less travel / all mountain) will be equipped with 650B wheels for 2014.
Here is the video introduction from the brand and its pro riders :
Geometry is changing compared to the 26 inches models : adapted bottom bracket height to keep 26 ratio, longer chainstays and shorter headtube to keep the line.
Both 26 & 27.5 frames will be available on CRC store. Complete bikes for 2014 will be only 650B.
