Ergot wrench with 24 mm clamping interface: a must-have tool for bicycle maintenance
When it comes to servicing or removing specific components on a bicycle, having the right tool makes all the difference. Among these precision tools, the ergot wrench stands out for its versatility and efficiency. Today, let's focus on a specific model: a flat wrench featuring an ergot interface on one end and a 24 mm clamping interface on the other, with a thin 4 mm profile. A tool designed for demanding cyclists and bike mechanics looking for precision.
What is an ergot wrench used for in cycling ?
The ergot wrench is used to lock, unlock or hold specific rings or nuts designed with ergot slots. It is commonly used when working on bottom brackets, hub nuts, or during adjustments on tension or internal locking systems.
It allows:
-
Secure holding of the part being handled.
-
Removal without damaging the surfaces.
-
Precise intervention on sensitive bike components.
Dual interface for maximum versatility
This flat ergot wrench stands out thanks to its 2-in-1 design:
-
Ergot interface on one side
Ideal for engaging with specific rings featuring ergot slots. The ergot provides firm contact and prevents slipping, which is crucial when working on aluminium or treated steel components. -
24 mm clamping interface on the other side
The 24 mm hex opening allows you to tighten or loosen hexagonal nuts, commonly found on hub axles, certain bottom bracket cups, or suspension and adapter locknuts, depending on the setup.

Why a 4 mm thickness ?

It perfectly complements essentials such as the pedal wrench, cone wrench, cassette remover, torque wrench, crank extractor, and more.
