While I was working in the attic with Ezra he noticed that Judi was quite rusty in parts, mainly because I put her away without properly scrubbing everything down. And so I took apart her drivetrain and he helped me scrub. But when I went to reassemble the rear wheel I noticed that it felt a little loose and wobbly. The middle gears had felt a little strange when riding lately, and that explains it. So I took apart the freewheel and overhauled it. Now it is running smoothly.
