Disraeli Gears

I took my bike in for a service on Saturday. I'd always intended to have it gone over before London/Brighton, but my hand was forced by difficulty moving down from 2 to 1 on my front cogs during my last training ride. This is important as there be hills 'twixt here and there.

It turns out that through indolence I have chain stretch which has been left untreated for long enough for my rear sprockets to be worn as well.

Replacing worn sprocket cassettes and chainrings after missing the chain replacement window is much more expensive than simply replacing a worn chain in the first place.

Likely bill approx £100.
