Park Tool LRT-3: The Professional Lockring Tool for Specialized, Cannondale & FSA Modular Cranks
Master the maintenance of modern drivetrain systems with the Park Tool LRT-3, a purpose-built addition to any serious mechanic´s collection of transmission tools. This precision instrument is expertly designed and built to remove and install the direct mount lockring that retains front chainrings found on some Specialized®, Cannondale®, and FSA® modular cranks. When working on high-performance components, having the right tool is not a luxury—it´s a necessity for preventing damage, ensuring proper function, and maintaining the integrity of your bicycle´s transmission.
The LRT-3 is engineered for a perfect, secure fit, providing confident and secure engagement with the unique lockrings used by these leading brands. This precise interface eliminates the risk of slipping, which can cause frustrating and costly damage to expensive chainrings and crank arms. Constructed from premium 4140 heat-treated steel and plated for exceptional durability, this tool is built to withstand the rigors of daily professional use in a busy workshop, guaranteeing a long service life and reliable performance every time.
For the most precise and safe assembly, the LRT-3 features an integrated 36mm hex drive, specifically designed to be used with the Park Tool TWB-36 Crow Foot and a quality torque wrench. This essential combination allows you to tighten the lockring to the exact manufacturer-specified torque value. Achieving correct torque is a crucial step for ensuring the long-term reliability and safety of your entire bottom bracket and crankset assembly, preventing issues like loosening or premature wear.
