I've been running Tririg Alpha X bars on my bike (2017 BMC TM02) for about two years. The Alpha X stem mounts to the steerer tube via a single bolt wedge style steerer clamp, as many of you know.
During the process of installing Di2 on my bike, I noticed the steerer tube is "imprinted" where the stem wedge clamps to the steerer, see attached pic. Tririg recommends 15-18 Nm Torque on the clamp bolt, but I've normally torqued to 12 Nm without any issues. (I was nervous about the amount of torque on this single bolt, so I didn't want to torque to 15 Nm unless I had issues with the stem slipping)
The lower edge of the indent looks like a crack to me. It has a sharp edge and as far as I'm concerned, it's done and I'm going to replace it. I might ride it on the trainer until I get a replacement fork.
Has anyone experienced this with the Tririg style clamp? Any idea where I went wrong? How can I avoid having the same issue with the next fork?
Thanks.
