i know its been a while but any help would be greatly appreciated, if found that the sizing of the seatpost on the carbolite frames is an irregular size and am having trouble finding a replacement or alternative so i can get a decent saddle? would anyone familiar with these bikes know of any solutions or have any suggestions. thank you in advance for any help rendered, ive hit a wall as none of the shops around me know where i would be able to find something like this.
