I purchased a bike with DI2 Dura Ace shifters but it came with a factory Ultegra 11-28 cassette. It just put the finishing touch on my Bike. You cannot really justify the cost for the small amount of weight savings but I am happy with it just the same. This is a new purchase so I can't speak to durability over the long haul but so far so good!
I purchases the 11-28t Medieval Tray thinking it would be the correct size to serve my boars head on to my party guests. I was wrong, I should have purchased the 11-30t option. Great finishing details, I'll guess this will have to do as an appetizer serving tray for now.
