As a rough guide, how often should chains be replaced on geared bikes? And how many chains do you go through before replacing a cassette, again, rough guide? I have a chain-checker but wanted to know if it's worth replacing every XXXkm or so.
I probably go through 3 a year on my main bike.
In summer I will run a semi-expensive chain, but will run cheapo £10 chains in the winter and change more often, as eventually they just become a total arsehole to clean.
