Had a five-speed Carlton at one time. But I don't recognise this.
Could you explain?

Lord help me for saying this, but 'Daily Mail' types probably think
cyclists all still use them, and those that don't have EverReady lights
should be jailed.

I've still got most of these but also

complete rod brakes

dotlocs for kids bikes

front fork tennis raquet holders

cottered BB axles

rubber pedals

Think back to when frames consisted of 3 bits of 531 (or 18/23 on cheap
Raleighs, which is probably some sort of gas fitting nomenclature) with
depleted uranium for the rest; The cheap Raleighs etc had the rear
stays soldered or Bostiked to the top of the seat tube, but with the
flashy Carltons the two tubes were made as one piece and joined
together by a small loop of steel that went over the top of the top
tube. A few very flash Raleighs (who presumably owned Carlton) were
made this way. I picked up a Carlton 531 frame at a boot sale a few
years back, weighed a lot more than a modern 501 but at made a good
£40 hack in the free ads paper a few weeks later ;-)

Eee when I were a lad I had one of those too. AIUI the wheel diameter was
irrelevant to the function and so was the distance from axle centre and they
weren't different ones for different sizes, because all they did was count
the number of wheel revolutions, not the actual distance. To get the
distance, if you wanted it, you had to multiply the number of revolutions by
the wheel diameter.

???
mine was even calibrated in miles; I think it was further than 6 wheel
revolutions to my friend's house.

ah just though of another bygone bit; those split links with a circlip
type thing, my chain broke on way to said friend and a passing motorist
just happened to have one. It was only after he repaired it much to my
gratitude and drove off that I realised it would not go through the
rear mech so spent the whole journey doing 3/4 pedal strokes ;-)

quite aside from having a senior moment, Shirley you mean circumference?

The mechanical odometers weren't trouble free by any means. At high speeds
they became unreliable, and eventually the gears inside wore out, especially
if they regularly got wet. They got in the way when removing/replacing the
front wheel (eg for punctures) as they were mounted behind the wheel nut,
and then had to be carefully repositioned to work properly. You can get a
cheap computer from Aldi or Lidl when they offer them (as little as 3 or 4
squid), and ignore the info you don't want!

Erm, do chains not have these anymore?

Mine does. (The circlip is a bit bent though!)

These tyres are still available. I know because I put a new one on my
back wheel a couple of months ago.

I need a new cotter pin for my left-hand pedal as the nut keeps
working lose. I've heard of "cotterless cranks" but have never seen
one. If I can find cotter pins for sale I shall buy two ..... so that
I can chuck out the first one I try to fit after I've bent the screw
threads whilst hammering it into the hole!

From the content of this thread, it sounds like My New Bike [a
mythical beast which may be a Brompton or may be a pannier-laden
full-size tourer] will contain no parts I recognise!

Was them black, with the bottom end of the back one painted white? with a

As a matter of interest, where in the world are you? Cranks using cotter
pins are now vanishingly rare in the UK.

I needed a new one recently, and the LBS said "I think we might have one
out the back somewhere, hang on while I have a look". (They did.)

(And my mechanical odometer isn't on the shelf I thought it was, nor
in the next most likely box (I was hunting for something else), so I
withdraw my offer of it for postage at least until I happen to come
across it.)

If you are in the UK send me your postal I'll send you some - milled or
round - your choice.

"Vanishingly rare" is a bit of an exaggeration - there are plenty of
them still around. Oh, and be a bit careful buying cotter pins because
there are two sizes and they're only a tiny bit different in diameter
(6mm and 6.5mm if memory serves).

I'm in the Wirral (UK).

I got my bike second-hand off someone who'd bought it second-hand
...... so it's at least third-hand but I don't think it's *that* old;
maybe late '70s, early '80s?

Thanks Sandy. It's not urgent (although it only takes a couple of
miles for the nut to loosen) so I'll have a look in the LBS and give
you a shout if I can't find any.

Coterpins were the bane of my young days on my raleigh grifter ... used
to always end up with knackered coterpins .... I used to put it down to
my strength but more likely to my lack of bike maintenance skills

..... although I used to keep them tightened regularly - never really got
my head around the problem.
