Little warning about this lightweight carbon saddle I bought... Rail snapped on the first ride. I am 64kg and it was a ride on asphalt, so nothing too rough....
the big problem with the cheap 'no brand' saddles is that quality control is nonexistent, and so there's no consistency..
I've had one similar to this, rode 1yr+ and all good, know a bunch of people who had the same experience, but also of some cases of breaking in 1st use (like yours) or after some months
in the end it's just a gamble
