Cinelli Stem Size?

rusty bodie · Apr 14, 2016

Does anyone remember what diameter(s) Cinelli Record (1R) stems were available in?

Do I recall that they were available in two different diameters and when I say that, I presume that it was just the vertical shaft that slotted into the fork column and not the actually bar clamping region of the stem?

I can't for the life of me remember, but I don't recall this being an issue in this country in the '80s.

:?

Many thanks.

I think only in 26.4mm clamp - was it the XA that came in two sizes?

My understanding is that 26.4 was altered to 26.0 as standard in the mid 90's. I'm using 26.0 bars in both 1R stems I have, (one being 26.4, the other 26.0) - the clamp design makes this work without issue although I am probably stressing the clamp bolt.

I didn't know they still did 1R stems by the mid 90s, I might be out of touch though

Was that so it would creak more?!!

:x

It's such a small amount. The centre sleeve would often get ruined trying to join the bars and stem, so maybe that was the reason . ..

Re:

You could very well be correct - I might be thinking of the XA? However, one of the 1R's here is 26.0 - I noticed this when a pair of 26.4 bars didn't fit :facepalm:

Re:

I think folks just used 26.4 stems and tightened them a bit more on 26.0 bars - probably safe enough most of the time...

Ahh the heady days of over built components.

Try that now on a FEA component. Lol

22mm & 22.2mm for the part that fits into the forks. Most of the 60's/70's/80's French Frames I have use a 22mm internal dia steerer tube in the forks.

Except when tightening it up makes the clamp non-round, then you eventually get a crimped bar and it cracks.

Luckily i noticed the crack when i took it off to locate the creaking.
