Flat
Repairs
This easy repair
can be performed in just a few minutes if you complete the
task correctly. We have arranged a list in chronological
order for task completion.
Tools Needed:
Tire levers, patch kit or new tube, open end wrench (non-quick
releases), air pump
Remove brake cantilever wire so that you
can get the wheel off.
- Undo the quick release or get the
appropriate size wrench and remove the wheel from the frame.
- Completely deflate the tire if there
is any air left over in the tube.
- Use the tire levers to remove one
side of the tire from the rim. You might have
to use more than one lever to get the tire to come off of
the rim. Removing the whole tire is not necessary.
- Remove the tube from the tire cavity.
- If you are replacing the tube skip
down six steps.
- Find the puncture by inflating and
listening or inflating and dunking under water.
- Dry and clean puncture
area.
- Use sandpaper to thoroughly sand
the area around the puncture. This is the most important
part. Make sure you do this step well, sanding the area
increases the adhesive ability of glue.
- Apply a thin layer of glue and allow
to partially dry for 2-3 minutes before applying the patch.
(If you are applying an instant
patch, put instant patch over hole and rub area firmly to
set adhesive backing).
- After the thin layer of glue has partially
set, apply the patch over hole and rub firmly with fingers
or rounded object such as the tip of the plastic tire iron.
- Allow a few minutes for glue to completely
set and peel the clear plastic off of the rubber patch.
- Put some air into the tube so that
it holds a circular shape, not too much air though, it will
make it hard to get the tire back on.
- Make sure you check the entire inside
of the tire for any thorns, rips,
etc.
- Place tube back into the tire cavity.
- Put tire back onto the rim. This is
the hardest part next to getting the tire off. Make sure
the valve is slightly pushed in so that the valve itself
does not get in the way of the tire bead and clinching groove.
- You can use the tire levers to get
the last bit of tire back onto the rim. They will help you
"snap" it back on.
- Inflate tire and replace wheel onto
bike.
- Reattach brake cable.
- RIDE
