Park Tool LRT-3 Lockring Tool

Precisely machined for a perfect fit, the LRT-3 removes and installs the lockrings that retain direct-mount chainrings found on some Specialized®, Cannondale® and FSA® modular cranks. Features a 36 mm hex fitting for use with the Park Tool TWB-36 Crow Foot and a torque wrench (each available separately) to achieve proper torque. Heat-treated and plated 4140 steel construction ensures durability and long life.
