I had a blurb weeks ago about this bike when a KHS Rider had a prototype. Well, KHS has given the thumbs up for production. The 606 will feature a hydroformed aluminum frame, an X-Fusion Velvet fork, Nevegal 2.1" tires and a Shimano SLX rear deraileur, just to name some of the myriad of components on this geared hardtail. This is the first production aluminum mtb hardtail 650B frame.
I spoke with a few KHS folks at last year's Interbike and they were very open to the 650B format and even had a Tuscon setup with 650B wheels. I'd love to see a steel Solo-One in the future. They can call it the BSolo.
