5 Buy a tackle box with compartments to store all your extra bolts.
Every home mechanic has an old coffee can with a mixture
of small parts, with everything from bolts to pocket lint to old
lawnmower parts. These boxes are relatively inexpensive to buy,
but allow for quick access to any small emergency part when you
really need one. The only bummer is pouring out that can and
actually sorting through all the bits.
Keep a multi-tool and spare tube in your glovebox. If you’re one
of many riders forced to drive to the trailhead, be sure to have a
minimum number of tubes and a set of Allen keys to save yourself
a drive back to the house.
Always carry zip-ties in your pack or on your bike. If you carry a
pack, these are easy to throw in and can fix many trailside issues.
If you ride sans pack, sneak one or two into the cable guides like
this for an emergency.
Never store CO2 cartridges or chain lube in your glovebox. These
might be tempting items to store next to your tube and tools, but
they could burst in the heat of a car interior and cause a big mess.
Only apply chain lube to the rollers of the chain. Adding lubrication
to the outside plates of the chain will not help the drivetrain run
smoother and will actually attract dirt and dust.
Use a hitch-mount safe to keep your keys secure while out riding.
This one from Hitch Safe securely locks your keys and other
valuables in the 2-inch receiver hitch that comes standard on
many trucks and SUVs. This prevents you from not only losing
your keys, but also from crashing on them if you were to carry
them in your pocket.
