good morning everyone, i'm new to this forum and since i'm also interested in this x68 frame i wanted to ask those who own one if they would buy it again and if they consider it safe after reading that some users have had problems with seat post, fork and frame. thanks to anyone who can advise me.
i and welcome to the forum!
Great to see you doing your research before committing — it's smart, especially with a frame like the X68 that’s generated some debate. You mentioned concerns about safety, and I’ll try to share what I know and my own experience.
Yes, there have been a couple of reported issues — one fork failure and a minor crack in a seatpost. That said, I’ve also had failures on premium components: a €400 Gelu seatpost cracked within torque spec, and a Felt carbon frame cracked at the seatstays. These things unfortunately aren’t exclusive to lesser-known brands.
TanTan, the manufacturer, claims their products undergo ISO 4210-compliant testing (impact, fatigue, vibration), but they don’t provide detailed test results or even basic sales figures — which makes it hard to put the reported failures into perspective. I asked for sales numbers to do a rough risk estimate, but they understandably didn’t provide them. So yes, I was probably clutching at straws there.
Based on what I’ve seen and experienced, I personally still consider the frame reasonably safe — for me. But I completely accept that others may have deeper technical knowledge or different standards, and they may reasonably come to a different conclusion. Risk tolerance varies from rider to rider, and in my case, I’ve weighed the pros and cons and made a decision I’m comfortable with. Others may (and should) make their own judgment based on what level of risk they’re okay with.
Hope that gives a bit of perspective — and definitely feel free to reach out if you decide to go ahead or want
