Can we also do ignored maintenance?
I have a cassette on one bike that is on its last legs. I can generally flip into the 11T, and a couple of the larger sprockets, but 12T, 13T, and some of the others are all shot. So I'm either riding too hard, or too easy, and doing a half dozen shifts between the two
I now have a replacement cassette, but I replaced the chain a couple hundred miles ago, and don't want to replace the cassette without a newer chain. Especially with mid-winter riding.
I'm trying to think of other maintenance projects. I'm waiting for a few parts to arrive to build up another bike. Fixed a flat a month ago. Tinkering with the rear derailleur adjustment on one bike.
Oh, last fall I broke a spoke. Brought it in, fixed it, and discovered a cracked rim near a nipple. So, I dissembled, and swapped out the rim.
