Rebuilt my bike. Not a resounding success. Low point came when I finished the job only for Jenny to point out that my pedals were attached at 90 degrees.
Short test ride - not bad, bit of tweaking needed.
Chiro. Bum and hamstring have been niggly all week in spite of doing almost nothing. However there seems to be progress on some measures - nerve pain has reduced and strength and activation seem to be good. Another week off running though. I will kick this.
