New Zipp 898 on Kienle's Scott Plasma 5

Sebastian Kienle has been a monster of the sport for some time now. We caught the 2014 World Champ out on the Queen K preparing for his second rematch with defending champ and countryman Jan Frodeno. He was riding with BMC pro Ronnie Schildknecht, aboard his custom-painted Scott Plasma 5. We caught the champ towards the end of his ride, while he was sitting up navigating through town. So no slick in-aero photos this time. But the bike is still pretty nice. And it looks like he's riding a new prototype deep Zipp wheel, with a similar sawtooth pattern to the shallower 454. Perhaps this one is the 898, for its alternating 80mm-90mm depth? I have a feeling it will be announced soon.
