i have a full carbon saddle with 3d printed top from Racework. The carbon shell cracked. I'm still riding it because i can't feel it when i'm riding but... it's cracked. Generally i dont recommend getting racework products. Road use only. Idk when and how it broke.
Not sure if ryet is the same model or not, but i m pretty sure many of these "brands" just slap their logos on things, and they probably come from an OEM or 2.
I like the saddle though so i'd probably buy the same design, from a different seller.
