It's a Ostro v2 replica, you should've used Factor's recommended torque setting of 3-4 nm since it is the same system.
That's right.
I'm tightening it to 3 N now, but when I first bought it, I didn't know any better, so I tightened it to 8 N just as I was  :'(told. :'(

I ordered the tt-x71 frame in mid-August 2025, and it arrived at the end of September.
I noticed the seatpost was damaged about a month later, but I left it as is for a while.
Then, recently, it started making a strange noise, so I’ve been in contact with the Seraph seller since around February, but they stopped responding in April.
The warranty period is still valid, right?
Sorry if the translation was wrong and didn't come out right.

Hey, everyone.
Has anyone asked the seller about the recommended torque setting for the tt-x71 seatpost clamp? When I asked, they told me 8–10 N, so I followed their instructions—and my seatpost ended up cracking.
When I contacted the seller about it, they just played dumb and said the torque setting was correct.
Seriously, Seraph sucks.
They’re probably just trying to wait until the one-year warranty on the seatpost expires.
