Not normally into large text decals but that really works.

No, but he will get back to you if you send your footman round to his establishment to leave your calling card with his doorman

They are a bit tatty now, I might remove them. I think I was given some spare decals, but not enough. I wonder if 1 per side would look half-arsed?

Does he have an address then?

"Steve" doesn't give me much to go on and UTFS isn't helping either

Waw c'est un beau vélo ça ! il a l'air rapide >>>>>>>>>>>>>>>>>
ces roues !!!
Brake caliper VMB : ) Chorus or Centaur ?

Speak to stayer cycles or SBC or clever Mike etc he collects from a lot of bike shops now. I think his company is called something like Arum finishings

Pm-ed

Athena freebies :-) I quite like the silver touches actually.

I've got a pair of Athena for sale if anyone's looking!

S-Works (20mm setback )

Thoses brake calipers are the most beautiful ever produced for me

She's pretty much dialed now! Only change I'm going to make is to put fabric saddle on it.

Also I want to try a 100mm stem as I feel 90 with the on one Mary bars is a little too short!!

But she rides lovely and the rack is bomb!

Arum finishings

Aurum. Yeh good stuff Ive seen from there.

Please.

Just measured the bars that I was going to put on the new build and they’re slightly too wide. There were definitely bought second hand a long time ago.

Youre right, I should not lie to myself

You CAN fit a ISO crank on a JIS spindle, it’ll just stick out 4 or 5mm more then the bb measurement. So you’ll never find a JIS spindle short enough for that Crankset.
I’ve been running TA cranks on 107 Shimano BBs for years.

This is a myth. People assume that because it was on Sheldon Brown, it must be true. It's a pity he didn't live to correct this, because it gets rolled out as fact every time the subject is discussed on any cycling forum, and asserted as an absolute fact by people who have clearly never measured a pile of square taper bottom bracket spindles to see what the difference really is.

Regardless of any JIS/ISO confusion, you should always carefully inspect any square taper assembly, even one which is supposed to be a proper match from the same factory, to ensure that the bolt head doesn't touch the end of the spindle and the crank doesn't touch the runout of the taper at the big end.

My Royal H has a modern TA crankset I ran it with a 107 Shimano BB for a few years, I tried it on another bike with much larger chainstays and the the ND side hit the chainstay. When I went to reinstall them on the Royal H I installed them with and 111 Centaur BB and it fits the same.

I also ran a GPM strada cranks on a Shimano BB for about 7 years.

So yeah, I’m not so convinced it’s a myth.

That's already half the error you originally claimed, and just 1mm different from what I would predict if you asked me to guess at a starting point for substituting JIS for ISO.

If you look at all the potential sources of axial displacement error at the pedal end of the crank which are generated by the boss/spindle taper interface, you'll quickly realise that you can tell nothing about the "standards" from assembling one crank on two BBs, especially if you are just eye-balling it rather than taking proper measurements with the cranks in all 4 possible orientations on the spindle and with consistent bolt tension. How precise is your torque wrench?

If you wan't to reverse-engineer the standards, you should probably take at least 10 samples each from 10 manufacturers (5 JIS, 5 ISO) into whichever room your CMM is kept in, but my previous advice stands: check every individual installation for correct fit, because wear and tolerance stack happens. Either that or ditch the stupid things and get some cranks with a proper spindle attachment.
