It's easy to be a bike to work day hero and to improve the ride for many bike commuters.
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
I bring just the basic 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
