Did you clean the steerer tube with alcohol/degreaser before installing the stem? In my case, a little grease from the headset bearing always got onto the steerer tube, and that's why the stem slipped.

Yeah, the steerer tube is clean.

You have the expander plug in and tighten? Starting with the easy check
When you tighten you stem, the end don’t touch each other, right?
You use carbon paste between fork tube and stem?
Since you have an aluminum stem and with the expander plug in place, I personnaly wouldn’t hesitate to increase torque on tightening screws a little; I am no bike mechanic so maybe wait one or two others to comment first lol

Yeah, I actually tried a different expander plug but still no change. The stem bolts are torqued to 8 Nm, which was the max recommended.

Still having problems with the front end on my bike. Chris sent a new alloy stem, but I still have the same problems- even torqued to spec the handlebars can be turned. Also, the fork rocks back and forth like you can see in the video. Has anyone else run into this or have any ideas for how to fix it? Thanks!

Has anyone solved the rotating handlebar issue? I got a replacement stem from Velobuild, but that didn't solve the problem.

Road Bike Frames, Wheels & Components / Velobuild TT-023 Issues
« on: December 06, 2025, 06:02:59 PM »
Just got a Velobuild TT-023 framset. I had my local bike shop build it up and they're concerned that it's not safe to ride. The front end/stem flexes so much with weight on the handlebars it loosens up the headset. Also, even with everything tightened down, you can still rotate the bars independent of the front wheel.

I emailed the company and I'm waiting to hear back. Just curious if anyone else has had this issue or has any troubleshooting ideas. Thanks!
