tyres: 4,500km

4-5k

wheels trued: 2,000km

only when I whack something

new chain 4,000km, as LBS said i will need a new back sprocket at
8,000km, so if i change my chain now slightly early it will be ready
to change agian when the back cog is ready.

probably the same.

handle bar tape: 3,000 km but it depends how hot and hilly.

Tape.. usually only if I scrape something.Good quality cork.

rims?
pedals?
Cleats?
not yet

cables?
never.. unless they fray. Squirt of suitable lubricant down the tubes
will revive them.

brake pads?
probably same as tyres. 4-5k

30% hills, and 80% of traffic light action.
seat?
nope. looks ratty from a couple of falls, but still works ok where it
counts.

frame?
forks
not yet. second hand bike, I've got probably 30k and counting on it.

whole bike? does this depend on how you ride/ what you ride on/ amount
of hill climbing/ amount of sh1ty roads?? What is the worst everyday
treatment that will age a bike the quickest? potholes?

For tyres/chain/rims/brake pads. It's definitely water + road grime.
I used to ride past a concrete recyclers (thackarey st bridge,
anyone?) and the wear from 1 block of riding through that **** in the
wet was unbelievable. Like soaking your chain in abrasive powder.

Potholes tend to do repairable damage (unless huge): pinch flats and
out-of-round rims.


How many km's do you do per week/ per year?

Average 200k/week (purely commuting). Probably 9.5k/year.
