Just spotted this https://www.spacycles.co.uk/m20b0s133p4 ... m-brake%29
User serviceable sounds good..
Several versions available for different brakes/ axles.

I wondered if anyone had any more details..

I’ve used the bridge on many an audax, at all times of day or night... It is always a highlight.
Very much hope that sense is seen, soon!

Just to add my own best wishes.
Get well soon Brucey!

Thanks to those updating this thread too

When I ran the XD cranks with 10 speed, the chain would occasionally get stuck. Usually when dropping to the small ring from middle, at the base of a hill. I suspect the (ergo)shifters, which we’re very slow and clunky, (due to friction in the cable run, which I could have sorted, but never did...) didn’t help matters. I think the cranks would have been ok with deft use of down tube levers...

Hamster, if you are selling the cranks and rings, I’d be very interested. Will PM.

Only for the symbols not the names of the units, so N but newton, W but watt, Pa but pascal.

good point!

Newton, from Isaac, so given a capital letter, same with Watt and Pascal amongst others...

No idea about the cranks though!

https://en.wikipedia.org/wiki/Antoni_Gaud%C3%AD Quite a monument!

.. and strangely compelling. Think I’m using/ have used/still have mouldering in a box somewhere 3 or 4 from the first page..
Including those exage ones with the scalloped shape that was perfect for holding mud.

Keep going!

If you are thinking about going a bit further with you audax rides (and be careful here.. one minute you're wondering if you can ride a 300, the next minute you're lining up for Paris-Brest-Paris.. ) A dynamo hub would be worth considering. SP make the lightest, SON make the ''gold standard' and Shimano make lots!
They are all the province of the custom wheel builder though.

Thanks for that Mr B,
I’ll post it on the Derby Merc watts app

Vince at the above ( also in hailsham) may be able to help, or know someone who could...

Great place to dry your gloves during the caf stop

Vince https://colwoodwheelworks.co.uk/ is a mine of information, and spares, for all things Sturmey.
Worth a try

I agree that the terms used are not important here.
But....
...At a general sort of a level...
Metal molecules is incorrect because of the type of bonding present.

Non metals bond covalently, by sharing electrons, in materials like carbon dioxide and water. These small entities are molecules and have weak attractions for other molecules around them. (Giant covalent structures exist too, like graphite).


Metals and non metals form ionic bonds, with the metal donating electrons to the non metal. The bond consists of the electrostatic attraction between the oppositely charged ions. This can form large crystal structures, like salt (ie sodium chloride) crystals. They can be of any size, and so are not molecules

Metals have metallic bonds. The metal atoms outer electrons are lost, leaving lots of positive metal ions, and lots of delocalised electrons. The metallic bond is the attraction of these ions for the electrons in the sea of delocalised electrons. It may be a few metal ions, or billions, this is why they are not termed molecules. This type of bond gives metals their properties of flexibility, conductivity etc. (Metal structure is more complex than this, but in essence I think it’s true)

So, generally, molecules refers to small, covalently bonded (ie non metal) entities.

As I say, of no importance to the topic discussed, but

Does it look like this?
