Couple hundred km on this now and no issues, did a fairly hard stress test before taking for a ride and seems to be of good quality, will update if there are any issues in the future.
The stem cracked immediately when I tried to fit it to my bike. I used a torque wrench and was very careful not to over tighten but it still cracked. I messaged the company about this, asking for a refund, and they didn’t reply. Not impressed.
