Ultralight Carbon Fibre Bike Saddle

Product Description

Keep the bike light without giving up support on longer rides. This ROCKBROS saddle combines an ETPU foam surface with a carbon-fibre composite base and hollow chromoly steel rails, balancing cushioning, stability and a nominal weight of 180 g.

The zoned support surface helps spread pressure, while diamond-shaped openings allow air to move through the saddle and make rinsing away road spray and mud easier. Its slim profile gives the thighs room to move, and a rear mounting point accepts compatible ROCKBROS rear lights or saddle accessories.

Designed for road bikes, mountain bikes and folding bikes, it suits riders looking for a lightweight saddle for everyday training, weekend road rides or mixed-surface cycling.

Key Features

Zoned ETPU Cushioning

Supercritical ETPU foam supports the sit-bone area and helps soften vibration while keeping the saddle responsive.

Ventilated Hollow Design

Diamond-shaped openings encourage airflow, help manage heat and make the surface easier to rinse clean.

Lightweight Composite Base

A carbon-fibre composite base adds support and controlled flex, bringing the complete saddle to approximately 180 g.

Hollow Chromoly Rails

Hollow chromoly steel rails provide a strong, impact-resistant connection to the seatpost clamp.

Streamlined Riding Profile

The narrow side profile follows the thighs more naturally to reduce unwanted contact while pedalling.

Rear Accessory Mount

A rear mounting point is provided for compatible ROCKBROS rear lights or saddle accessories.
