Decided to run Fredo as a six-speed rear wheel to free up a 7-speed rear wheel for Blue Bella. Adjusted the derailleur limits and gave the bike a dusting and wipe-down, ready to ride again. Swapped the matching front wheel, too.
Removed the Campagnolo Racing Triple crankset from Bella and put the Sugino back on. Will probably sell the Racing T, which was bought for Blue Bella, but causes toe overlap at 175mm.
Put Fredo's 7-speed wheel on Blue Bella, and got the MicroNew rear derailleur replaced with the Tourney, and tuned so it shifts perfectly. Removed a stuck handlebar plug, and got the end of the bar tape tucked in properly. Much better. If I can wrap the left bar as well as the right one, she'll be done and ready for a test ride tomorrow.
