Description
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.
