FSA Gossamer BCD90 Chainring: Optimal Performance for Modern Groupsets

The FSA Gossamer inner chainring is a reliable solution for those seeking quality components in the cycling sector. Made from lightweight aluminum, this 30-tooth chainring delivers efficient power transfer through the pedal stroke. With a 90 mm BCD and a 4-bolt configuration, it fits seamlessly into the specified cranksets. Declared compatibility with the 46-tooth outer chainring ensures a balanced gear ratio for a wide range of riding conditions, while maintaining consistent system mechanics.

Technical Compatibility and Groupset Versatility

This component is designed to work in synergy with Shimano 10/11-speed groupsets, SRAM 10/11-speed and FSA 11-speed, delivering broad versatility. The FSA Gossamer crank is the primary design reference, defining the geometric and mechanical specifications. Its adaptability to multiple drivetrain standards makes this product particularly suitable for upgrades or replacements on road bikes equipped with these drivetrains. The precision construction maintains tight tolerances, essential to prevent slippage and ensure smooth engagement.

Component Installation and Maintenance

Installation of the inner chainring requires attention to alignment with the locking holes on the crank, ensuring that the bolt circle is correctly centered. Periodic maintenance includes cleaning and checking tooth wear, which is particularly important to maintain consistent performance over time. Being made from lightweight material, the chainring helps reduce the overall weight of the crankset, a key factor for cyclists focused on aerodynamic performance and energy efficiency while riding.
