What is the Park Tool DCW-4 Cone Wrench used for?

The Park Tool DCW-4 Double-Ended Cone Wrench is a 13mm and 15mm thin wrench designed for adjusting cup-and-cone wheel hub bearings. Cone wrenches need to be thin enough to fit into the narrow gap between the cone and the locknut on a threaded hub axle, and the DCW-4 is manufactured from thin heat-treated steel to fit precisely where standard wrenches cannot. Made from nickel-plated heat-treated steel for durability, it fits 13mm and 15mm cones found across a wide range of road and mountain bike hubs.

Cup-and-cone hubs still appear on a large portion of bikes in regular use, from entry-level road bikes to classic steel frames and commuters. The small tool size also makes the DCW-4 easy to carry in a kit for roadside hub adjustments. If your bike has Shimano or other threaded cup-and-cone hubs, a cone wrench is a required tool for any hub service.

FAQ

What hub types use 13mm and 15mm cone wrenches?: The 13mm and 15mm sizes cover the most commonly used cone sizes on Shimano and other threaded cup-and-cone hubs. Front hubs typically use 13mm cones and rear hubs typically use 15mm, though this varies by hub model. Confirm your hub's cone size before ordering.

Do I need a cone wrench for sealed bearing hubs?: No. Sealed cartridge bearing hubs do not use adjustable cones and do not require cone wrenches. Cone wrenches are only needed for cup-and-cone style hubs with threaded cones and locknuts.

How many cone wrenches do I need for a hub overhaul?: You typically need two cone wrenches of the appropriate size: one to hold the cone stationary and one to tighten the locknut against it. For the DCW-4's 13mm and 15mm double-ended design, one wrench can serve both positions if the cone and locknut are both the same size, but most setups require a second wrench.

Best For

Cyclists and home mechanics servicing cup-and-cone hubs on road bikes, mountain bikes, and commuters. Essential for any hub overhaul or bearing preload adjustment on threaded cone hubs.
