All,

Just want to find out who here has had any experience with a Pro Vibe 7s Alloy Stem.

I only tightened it to <3nm and it has still appears to have compressed some layers of carbon of my steerer tube. Seriously disappointing, ive never had this experience with my 3T stuff.

Ill post pictures shortly.

Cheers

Seems like you're just asking this to get to 30 posts, but I'll bite.
I use the Vibe on 3 bikes and they're all fine with around 4nm.
(Easton EC90 SLX, Ritchey WCS, and a generic Chinese fork)

I've got the Vibe version, not the Vibe 7s, and was tightening it to 5-6nm without a problem to my CAAD10 carbon steerer tube.

some compression on steerer tubes is not unusual. did you tighten both screws uniformly?

Has that steerer tube been lacquered? Most come bare. Just as well to roughen it up with a bit of sandpaper if it has been lacquered. You might also find that this removes the indentations, especially if the lacquer went on quite thick.

yes uniformly tightened, it ended up cracking the steerer tube (i doubt ill use it on my new caad 10)

I'm using a the same stem on my S2. Steerer is fine.

I had the same problem and had to have the forks replaced. But I made the mistake of cutting the steerer too short. Now I always leave a little bit of steerer poking out above the stem and run a small spacer on top.

user error? or steer tube issue? seems unlikely that the stem is the problem giving others' feedback

I've used two different Pro Vibe 7s stems on two different carbon steerers (a Pedalforce and a Flyxii, so not exactly the highest quality carbon) for 3+ years and never have had an issue.

My view is it was a steerer tube issue. I have built many bikes and never had a problem EVER! As i said at 3nm it shouldnt do what it did. Im thinking it testing it on one of my broken frames first before putting it on the caad.
