Cycletex, yes please do keep us posted. Antelope 70cm and I have PM'd back and forth and communicated with KHS and its dealers about this product for quite some time. I have to say that KHS has done a pretty good job at taking the wind out of their own sails.
Ironically, I just called our local KHS dealer the day before your post. These bikes were said to arrive almost 2 months ago, always a week away from shipping. Still, nothing in and no word? And as you point out, the limited information KHS gives on their website is baffling? What info we got we had to really dig and call for. The dealers didn't have as much info as we did. Anyhow, just know that this bike only comes with 200 mm crank arms, which if you're 6'4"+ and follow Zinn's philosophy on crank arm length, is just fine.
I still support ANY effort to accommodate tall and/or heavy riders with designed production bikes, and I hope the eventual follow through with KHS will be worth the wait. I have personally been eyeing other options though. Antelope has gone in a different direction too. At some point you just cut the line.
