How to measure which Hexnut you need.
TIP: If some part of your axle sticks out, then you do not need to remove the wheel nut to measure the axle

FRONT WHEEL:
Most Front Wheels use M9 [9mm axle diameter] If your Front Wheel Nut fits your rear wheel or its for VanMoof, Miche and DuraAce, use M10 [10mm axle diameter] For vintage bikes please double check. 3/8 [9.52mm axle diameter] is rarely used. Best to check your axle diameter.

REAR WHEEL:
Most Rear Wheels use M10x1mm [10mm axle diameter]
Fits all Single Speed and Fixed rear wheels.
Also suitable for Rohloff, Bion-X, NuVinci, VanMoof Front and Rear, Miche Front and Rear, DuraAce Front and Rear. (not compatible with Sturmey-Archer rear hubs, as these are non metric)

SHIMANO ALFINE/NEXUS:
3/8 - Alfine/Nexus [9.52mm axle diameter, 3/8' x 26tpi]

HOW IT WORKS:
Our Hexnut is threaded exactly the same as your existing wheel nut. It tightens with a 6mm Allen Key / Hex Wrench Once the HexNut is installed, secure against theft with a 6mm Hexlox.
Only 1 Hexnut per wheel is required for full security.
