|Stem advice for carbon steerer's .......||G-T-|

|I was wondering if the clamping device for the Thompson stem vs. lets say TTT Forgie would be better for a carbon steerer ? Thanks.
It may be a mut point anyway as I need a 31.8 and I don't think Thompson goes that large.
What stem would you recommend 10 degree rise 1 & 1/8th ?

|I was pondering the same thing this morning while reading through the manual for my Ouzo Pro fork (slow day in NC).
...and I quote: "The Ouzo Pro carbon fork must be used with a 'circumferential' clamp style stem. Use of a 'pinch' or 'wedge' clamp style may cause damage to the steerer tube which may result in rider injury or DEATH."
Well, there you go. BTW, I now have a 120 mm black Thomson stem for sale. Interested?

Q - Are Thomson stems approved for use with carbon steerers?
A - Reynolds, Look, Time, Wound Up, Rock Shox, and True Temper have all approved Thomson stems for use with carbon steerers.

|Here's the answer from their tech dept.:
we do not recommend the use of compression clamp stems because this style of
stem damages carbon steerers. But when Thomson designed their stem they were
thinking ahead of the rest of the stem makers and they made their stem
carbon friendly. The Thomson stem is compatible with our steerer because to
spreads the clamping pressure around more than 180 degrees of the steerer.
...good enough for me.

|... I specifically emailled Reynolds with respect to using a Forgie (standard bar) with their full CF products and got the offical OK...
I've got Forgies on 3 CF steer'd bikes with no problems...
The only other thing I'd add is... the original Forgie is an old design, and many stem makers have addressed the CF steerer problem with "better" clamping designs. If you had a specific model in mind, you might email 'em too.
Be the bike.
