...minor stuff...
Nothing major: derailleur adjustments, tire patches, brake adjustments, fitting adjustments, tightening loose stuff, temporary repairs.
But, in my office of 10 people, there are 5 bikes... so there is always something being done.
Just this morning, one guy patched a tube, then repatched after finding the rest of the thorn during inflation. Another guy performed a temporary repair to a rear fender.
Yesterday I had to adjust my rear deraileur due to accidentally messing with it during a tube repair on the way in to work.
So, there's always something going on...
