Answer from kestrel:
The best stems for the Kestrel carbon bars will have a lot of contact between the insides of the stem plates and the bar....this spreads the binding force of the stem more evenly over a larger area.....Don't know that that particular stem would damage the bar but there doesn't appear to be a whole lot of contact area...Best stems have been the ITM stems....Ritchey WCS stems.

Subject: Compatible stem?
Im interested in your ems pro/sl handlebar but I would like to know if it is compatible with 4 point stems such as the syntace stem I have attached.
The people of syntace told me that this type of stems are 'handlebar killers' and that I should check with the bar manufacturer.
