Shimano refused to admit these even existed (this Revolt was on the Shimano stand)...it's a story I've heard the web-over! The rims, spokes and nipples looked pretty standard - nothing special - laced to standard Saint hubs, so maybe these were stickered-up OEM rims, but as the Athertons have been running Saint-branded rims too this year, it would be hard to believe that Shimano don't have something in the pipeline...
