The derailleur screw kit from Ti Queen delivers a comprehensive drivetrain upgrade tailored for Shimano road components including R9250, R8150, and R8050 series. This titanium bolt set enhances both durability and performance across your entire drivetrain—from derailleur pivots to shift plate bolts.
Made from aerospace-grade titanium alloy, these derailleur screws offer an ideal balance of weight savings and strength. Thanks to titanium’s superior strength-to-weight ratio, you’ll reduce rotating mass while maintaining rock-solid fastening. Riders familiar with switching from steel fasteners report meaningful durability and less corrosion-related wear—even after many wet-season rides.
Lasting Titanium
Every screw in this kit comes CNC-machined for perfect fitment to Shimano’s tolerances. This ensures precise shifting alignment and reduced risk of loosening under vibration or flex—a must-have for riders pushing aggressive cadences in all conditions.
To complete your lightweight upgrade, pair this set with Ti Queen’s ultra-light Brake Mounts adapter or the sleek Centerlock Lockring upgrade. Together, they deliver a comprehensive titanium upgrade from drivetrain to brakes.
Installing this derailleur screw kit means upgrading beyond appearance—it’s about real, functional gains in lightness, reliability, and precision for every ride.
