Product Description

Park Tool FR-5.2 being used on a cassette lockring

Park Tool FR-5.2 Bicycle Cassette/Disc Brake Lockring Tool

Park Tool offers a full range of tools for bicycle cassette lockring removal and installation. The FR-5.2 fits 12 spline 23.4mm diameter tool fittings - the most common tool fitting found on 7-12 speed bicycle cassette lockrings, including models made by Shimano, SRAM, SunRace, SunTour, Chris King and others. Also fits Shimano disc brake lockrings with 12 internal splines, and top caps of some Rock Shox suspension fork models including Pike, Lyrik, SID, Revelation, Reba, and Paragon. Thin wall construction allows use without removal of cones and locknuts. The 1" hexagonal base can be used in conjunction with a socket, wrench, or bench vise. Heat treated alloy tool steel construction for a lifetime of use.

The FR-5.2 has 12 splines that are approximately 23.4mm across at the widest point. Center bore for axle clearance is 12mm.

PARK TOOL: YOUR GUIDE TO THE WORLD OF CASSETTES & FREEWHEELS

Campagnolo cassette lockring

CASSETTE OR FREEWHEEL?

To determine the type of rear sprocket system you have, find the tool fitting on the sprocket set. Spin the sprockets backwards. If the fitting spins with the cogs, it is a cassette system. If the tool fitting does not spin with the cogs, it is a freewheel system.

CAMPAGNOLO OR NO?

If you have a multi-speed cassette, you need one of two tools. If the cassette, derailleur, or shifter are labeled with Campagnolo, the tool for you is the BBT-5/FR-11. Otherwise, you will require a tool in our FR-5.2 line.

THE RIGHT TOOLS FOR THE JOB

In addition to the correct tool, you will also need a method of driving it (such as an adjustable wrench or 1" socket) as well as a chain whip to hold the cassette in place as you remove the lockring. Park Tool makes a full line of chain whips and wrenches for this very purpose.

Park Tool makes a full line of cassette lockring and freewheel tools to empower you to remove the rear cogs of virtually any bicycle. Here's a selection of tools similar to the FR-5.2GT:

Customers are mixed about the fit of the multitool. Some mention it's easy to use and has a perfect fit into lockring spline. It also fits pedals. However, others say that it doesn't fit on any of their 3 different cassettes and may slip with other cassettes. It's too big and doesn''t work with every mountain bike rim.

Park quality at knock-off prices. If only all their tools were this sensibly priced!
A quality Park Tools tool at a price that keeps you from looking for a cheaper alternative. The remover looks and feels like quality. Tight fit into lock rings means confident removals. Works with my Shimano 8-speed cassettes.

Reviewed in the United Kingdom on October 12, 2023
Color: BlackVerified Purchase
Great tool, fits both the rear cassette and Shimano centre lock brake rotors, good deep splines which seat well into the locking ring, with a deep enough recess to accommodate the axle.

Needs a 1in AF spanner, or preferably socket to fit onto a torque wrench, and of course a chain whip for loosening cassettes.
Quality tool, which should last the distance.
