This version has a small internal protruding fastening device and comes
with a metal shim for 1". Is it suitable for 1" and 1 1/8" steerers of
any material or should certain steerers be avoided?

Thanks for any help.

My understanding is that this clamp is not suitable for carbon steerers.
That is the reason Deda went to the two-bolt clamp on later models of this
stem.

FWIW - I have used this stem and clamp configuration on an alloy steerer
fork for several years and love it.

Regards,
Mish

probably fine for steel or aluminum steerers. to state the obvious, it
should discuss application in the instructions.

Thanks Jim & Mish.

The instructions only mention the two-bolt version.

Definitely not for use with carbon steerer - I had been running this
stem with carbon steerer for 2 seasons/5000 miles a couple of years
ago. Then I saw the stem on closeout in a Nashbar catalog with the
miniature caption "not for use with carbon steerer" - never geard or
read this anywhere else. Took the stem off to find my steerer tube with
two large cracks - lucky I didn't kill myself; had to buy a new fork
(and stem.) If you're not using a carbon steerer, it was otherwise a
good (although heavy) stem. I've switched to Thomson and haven't looked
back.
