Product information: Brand: ROCKBROS Surface material: Polyurethane composite Base material: Carbon fibre Department: Unisex adults Weight: 38210030001: approx. 207g; 38210031001: approx. 183g Height: Approx. 6 cm Width: Approx. 14 cm Length: Approx. 24.5 cm Colour: Black Features: 1. zoned damping: The bike saddle is arranged in a honeycomb pattern of dots, creating different cushioning zones: In the area of the sit bones, the saddle is reinforced and provides better support. At the rear of the saddle, where less pressure is exerted, the construction is relatively stable and soft. This results in a more comfortable ride. 2. ergonomic design: Streamlined, narrow front + Hollow and breathable design. The front end of the bike seat is narrower to reduce friction on the inside of the thighs. The rear end is wider to reduce pressure on the sciatic nerve. The hollow design provides ventilation and perspiration while reducing pressure on the genital area. 3. 3D printing technology: The cushion is manufactured using continuous digital light-curing printing technology to create an integrated, seamless, hollow lattice structure. This provides excellent support, stability and elasticity and reduces pressure on the soft tissue. 4. high quality materials: The seat is made of a wear-resistant polyurethane composite material. The seat arch is made of carbon fibre, which is characterised by high strength, toughness and dimensional stability. The use of high-quality materials guarantees a low weight (only 207g/183g) and a long service life of the ROCKBROS bicycle saddle. 5. versatility and comfort: The bike saddle fits most mountain bikes, road bikes and other types of bikes on the market. Fitting and removing the saddle is simple and straightforward. The side of the arch of the bike saddle has its own scale markings, which provides convenience for the user to adjust the installation of the saddle. Please note that the rail dimensions are 7*9mm. Make sure that your bike saddle is compatible with these dimensions. It is also recommended to use a torque spanner for installation and tighten to the torque specified on the bike saddle.
