I didn't realise that what I know as split pins are also called cotter pins.
The ones I'm thinking of are those used on old style cranks

This intrigued me enough to look it up because when I read @Alex321's post, I didn't know what he meant and presumed he was replacing split pins with some sort of wedge device. According to Wikipedia, calling a split pin a cotter pin is an American thing. First time I've ever come across it.

I didn't know that it was an Americanism, I've just always known the term cotter pin as an alternative name for split pin, so I assumed that was what you were talking about.

I had no idea that what @Jenkins has pictured above are also called cotter pins. You learn something every day :smile:

I have known the term cotter pin from the early 1960‘s with my first bikes. However I don’t remember it being used as a term for split pin when I worked in engineering in the 1970’s.

Lefty tighty. Get it righty.
Cotter pins, definitely. Horrible things.

Weinmann centre-pull brakes.

Clicky mileometers, and their route-planning equivalent, the map measurers with a little wheel that you traced your route and read off the distance from the appropriate scale.

My cycling clothing from the 70s and 80s would be a bit out of place in that none of it was cycling clothing. The only cycling-specific clothing I had was my rain cape.

I had some Weinmann 500 side pull brakes on my first serious bike. They were horrendously bad.

ISTR that centre pulls were cooler than side pulls. Side pulls were probably single pivot.

I don't recall Weinmann centre pulls being bad. But then, they were all I knew.

Centre pulls were good enough for this chap ...

Although, I think these were Mavic, which were cool.

Visually, I think for me those downtube friction gear shifters of old!

It might be getting older that does it, but not only do I have the occasional brain fart and reach down for non-existent down-tube shifters on my modern bikes, but yesterday, on my "alt-handlebar adventure bike", going down a hill, I went down to the drops that weren't there - luckily I realised before my front teeth hit the stem.
