I am thinking of fitting one to my old Moulton AM7 to get the bars I want
(26.2 mm dia) in the position I want (higher and slightly more forward).
What do you think?

I was looking at some adapters and they were pretty heavy. Maybe there
are some decent ones that don't weigh a ton. Apart from that they seem
OK.

I have one on my Randonneur for exactly the same reason - higher and
further forward, and so I could play with different stems easily until I
found one that was "right". The adapter has been working well for at
least 4 or 5 years, with nary a creak nor complaint!

Yes, the bottom bit works just like the shaft of a quill stem, and an ahead
stem clamps to the top bit just like it would clamp to a threadless steerer.

The shafts of these adapters aren't very tall, but a steeply rising ahead
stem might provide what you want. Definitely worth trying if you can't find
a suitable quill stem. A stem with a 26.0 bar clamp should be OK with 26.2
bars.

I've never heard of 26.2mm bars before. Is that Moulton being different for
the sake of being different?

The cheap one I got from SJSC (some long time ago) weighs about 150 grams.
Combined with a cheap 3T The stem, it's no heavier than the average quill
stem.

The ITM one is heavier. The Cinelli is much lighter.

Weight could be saved by reduced by replacing the steel bolt with a Ti one,
if you could find the right size. (I guess the Cinelli might already have
an alloy or Ti bolt).

No it's not Moulton it's more than likely my [censored] vernier !
The bars are relatively modern 3T Morphe.

Thanks to the rest of you for the quick replies. I'm off out next week to
get the relevant bits.
BTW does anyone know how stems are measured ?
Are the dimensions centre to centre? If so how do I know where the centres
are on one like this...http://www.gearshift.co.uk/acatalog/Stems.html
The one I'm looking at is the 40 degree 120mm one. I suppose that will go
with the adaptor at the bottom of the page. I'll phone them before ordering
though.

They'll be 25.8 then.

Yes.

Good question. I think it's supposed to be from half way down the stem,
from centre of fork steerer to centre of handlebars. Measuring along the
top from centre of centre should give you a good idea, though.

It will. A shim will be required if it's 1" at the top.

Think carefully about the length. 120mm is long for a 40 degree job.

An adjustable tall quill stem might be better if you're not too sure what's
required. Kalloy make one.

Which is effective, if somewhat heavy.
My oldest bike has one.
Might be the cheapest way to determine the angle/length required.

Other downside of my adjustable one is that the bar clamp is the older
single pinch bolt, not the newer "front loading", so switching to the final
stem requires a strip-down of one side of the handlebars to unthread them.

I have a bike with an adjustable Kalloy quill stem which does have
the two-bolt front loading clamp.
