I did a quick search and didn't see this specificly stated, but did see quite a few Ventanas with the Double Barrel. Does it fit with the 6" rockers and not contact the down tube with the reservoir? From the measurements on the Cane Creek site, it looks close.
I'm thinking about going with the air version when it becomes available.
