The intro slides for each category that we delve into - in the bike maintenance 101 session

2.  Glossary – parts of the cycle
 Tyre & tube service
 Wheel inspection
 Brake inspection & adjustment
 Chain wear & cleaning
 Cog wear & inspection
 Index shifting & adjustment

3.  Removing the tyre
 Inspecting the tube
 Fixing the puncture
 Diagnosing the cause (why bother? )

4.  Inflate tube
 Locate puncture – listen or put in water
 Mark hole
 Sand hole
 Patch hole (pre-glued or normal patch)
 Ensure proper bonding

5.  Overall -
 Wheels bend out of true all the time
 Spoke adjustment usually does the trick
 Damaged wheels – can be because of
 Impacts with rocks, potholes, curbs
 Crashing
 Grinding from caliper brakes

6.  Chain – very important to performance
 Highly vulnerable
 Tends to fail when under load
 Common cause of failure – rivet pulled from
outer plate
 Inspection – view chain from above, look at
each rivet for centering

7.  Rear cogs will eventually wear out
 Chain loads only one side, and that side
wears out
 Chain then rides high on the ‘shoulder’ of the
cog, causing it to slip under load
 Two-three cogs tend to be most worn, while
others are fresh

8.  Indexing: having a set distance for the rear
derailleur and cable to travel to engage a
specific gear.
 This distance is a function of the shifter and
derailleur working together

9.  Disc vs. rim brakes
 Pro-disc: reliable, good stopping in adverse
conditions, stop with bent rim
 Con: needs tighter fitting tolerances
 Pro-rim brake: easier tolerances, simpler to
fix on the go.
 Con: wet weather conditions, stopping power,
rim condition important
 Top tip: brake lever modulation is king.

10.  Brake for control, not only for panic stops
 Factors affecting control: lever placement,
cable system, alignment and quality of brake
pads
 Flat bar levers should be rotated to be in line
with the rider’s arms
 Drop bar levers can be moved based on your
riding style
