I swear to God this isn't a dig at anyone, but threads like that leave me baffled. I get new brake pads when the bike's serviced at the lovely Freeman's, Norwich. It simply would not occur to me to ask what brand they were. I admit I am completely knowledge-free about how my bike works, I ride it till the tyres go flat or the chain makes a noise like a chainsaw through concrete, then I get a chap in an overall to sort things out. Salute geeks or argue the toss over whether mechanial numpties aren't proper cyclists here.
It doesn't sound like a dig at anyone, so no worries there. I too live in ignorance of the names of brake-pad manufacturers. I don't even know who makes mine.
Nonetheless, I imagine you'd enjoy your cycling more if you started getting into the gubbins and clicky things that keep the velo working.
You've done fabulously to date - 4k a year for twenty years, including continental tours and no need to reach for a spanner. That's 80,000 miles with only bike-shop services. I take my hat off to you. If I'd catalogued the mishaps and niggly repairs my various machines have suffered over the past 80000 miles, it would be quite a book. Unpickuppably big.
However, there is a certain pleasure even in the simplest things like taking the stretch out of a gear cable or getting your brakes 'just so'. I know no-one who doesn't enjoy sorting bicycles, even my 18-year-old daughter gets quite into it.
There are shitty, dull jobs - like chain lubing and cleaning the bike, but even then you very often find little areas that require attention while you're getting your hands in there and having a look. It feels good to catch a little gremlin of a fault before it turns serious.
A solitary drawback is the rather silly number of specialist tools you need for some jobs... but few cost more than £15 and once you've got them you've got them.
Everything you need to know has been put on Youtube by a saddo in a shed with no idea about lighting and shadow. Have a go. You'll be glad you tried.
I've just remembered who makes my brake blocks! Campagnolo. Is there another reputable manufacturer? I rather doubt it!
