i wrote an email to merida-centurion group(theyre procraft aswell),product services the other day and they told me they cant give me the info that them and trialtech are related to eachother,but that this had to do with warranty rights management.
they said" we cant definitely tell you that these stems arent produced by the same manufacturer,but we for ourselves can speak out our warranty only for certain use.our stems are tested with dynamic loads highly above those appearing in "normal" MTB use,but we cant guarantee it will hold up for trials use."
just got me thinking to read it,so i asked here...
edit:maybe i should change the question to like "who used procraft without problems?" :wink2:
