Dating back a stretch to the 2008-2011 Dura-Ace 7900 group, Shimano offered these amazing Yumea 5 piece upgrade kits. Riders that had a 7900/7950 groupset could purchase and install these kits to elevate their Dura-Ace components to the next level beyond Dura-Ace. We managed to get a small back stock of these upgrade kits (in original retail packaging) for riders who have a vintage 7900 group and wish to remove grams while adding class and beauty.
