This thread has inspired me to order two (2) 7 speed freewheels for my classic steel bikes to stock the bunker. I wanted to get one but two seems better. A few weeks ago I ordered a 2 pack of flashing red rear facing LED lights from Amazon, $12.00 for the two. They are inexpensive and not robust in construction but they work fine. Ordered another 2 pack just to have on hand. Also several sets of chainring bolts. I want to put a few sets of BBs in the storeroom in the near future. In very good shape with respect to bulk brake and shifter cables, spare drive train parts, misc fastners and assorted bric-a-brac. On my "wish list" is a commercial quality ultrasonic cleaner. But I would be doing this regardless of the world wide health crisis, the impending social meltdown and the disruptions in the supply chain.
