ULLICYC Carbon Fiber Road Cycling Saddle Ultralight 242*122mm Full Carbon Double-Track Hollow Breathable Bike Saddle

The reviewer discusses the ULLICYC Carbon Fiber Road Cycling Saddle, noting its extremely light weight of 53 grams and full carbon construction. They mention that despite initial expectations of it breaking, it has been ridden for over 500 km without issues. The saddle has some flex, making it comfortable for rides up to about 2 hours, but for longer rides like a 4-hour London to Brighton, it reaches the limit. The reviewer notes a rider weight limit of 85 kg and mentions some imperfections in the carbon rails, with voids and rough patches, which are not confidence-inspiring. They also compare it to a similar saddle from another brand, which they consider more solid and cheaper.
