Glossary – parts of the cycle
Tyre & tube service
Wheel inspection
Brake inspection & adjustment
Chain wear & cleaning
Cog wear & inspection
Index shifting & adjustment
Removing the tyre
Inspecting the tube
Fixing the puncture
Diagnosing the cause (why bother? )
Inflate tube
Locate puncture – listen or put in water
Mark hole
Sand hole
Patch hole (pre-glued or normal patch)
Ensure proper bonding
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
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
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
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
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.
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
