On Bike to Work Day, I grab my bike pump, chain lube and a few simple adjustment tools
and ride down to my local bike trail or energizer station.
There, I join the fun and set up shop to do quick tire top-offs, chain lubes and bike adjustments for passing riders.
Step 1: Gather a few simple tools and parts
Floor Pump with Schreader valve for most tires
Presta Pump for the other tires
Chain lubes (they vary with preference of rider)
Crescent wrench (aka universal nut rounder)
Channel locks (aka nut knurler) to adjust loose headsets
A couple of rags
But you could also add:
Cone wrenches to adjust loose hubs
Bottom Bracket tools to adjust loose BBs and tighten loose cranks
And if you want to go in depth you could add:
Patch kit and tire irons
Spare bolts for attaching loose racks, etc
Cable clippers for trimming broken cable housing
Grease for lubing crusty cables
Spare brake cable housing and spare cable
Step 2: Mostly I put a little more fresh air in tires.
More efficient (easier and more repeatable for the riders)
More safe with better bike control
More flat-tire resistant
And it makes the riders feel appreciated.
I tell them I'm packing a little more spring air into their ride.
I just look at the tire sidewall for desired pressure range and use my calibrated fingers to check pressure.
But you could bring a pressure gauge.
Step 3: I also oil a lot of chains
She will be able to hear the birds chirping instead of her chain chirping.
I just apply a thin thread of oil to the top of chain while spinning cranks backward.
Takes 10 seconds and has no overflow.
Then I squeeze the chain with a rag and drag the chain backward through the rag
by spinning the cranks backward to wipe off any excess oil.
