Your baitcaster needs either 7×4 mm or 8×5 mm – depending on the model.
Search below for your reel or use "Search in page" to find it directly.
Your reel is not on the compatibility list? No worries – just quickly measure the shaft yourself. The crucial factor is the shape/size of the crankshaft (shaft) onto which the handle is mounted. The common sizes are 7×4 mm and 8×5 mm.

Tip: Image shows the difference between 7×4 mm and 8×5 mm.
Quick reminder: You measure the shaft, not the nut – and you need two values at the end: width × height = 7×4 mm or 8×5 mm.
Choosing the right baitcaster crank (handle) affects torque, speed, comfort, and control. Length, handle material, and knob size directly influence the fishing feel – especially during longer sessions or with lures that have a lot of resistance. This guide helps you understand the differences and find a suitable combination.
The length of the crank determines the torque: the longer the crank, the more leverage.

Aluminum is the versatile standard in baitcaster tuning.
Knob size is usually given by the diameter at the thickest point.
Before deciding on length or knobs, check the axle bore of your reel:
If your reel is not listed, you can measure the axle bore yourself with a caliper.

The ultra-light carbon crank arm from Gomexus is 75 mm long and equipped with the 38 mm Power Knob.
This single handle is ideal for anglers targeting strong fighting fish such as pike. Thanks to the carbon, the handle is very light and weighs just 38 g while still being durable, allowing for long and fatigue-free fishing sessions.
Equipped with precise stainless steel ball bearings that ensure smooth operation, this reduces friction and significantly improves the sensitivity of your fishing reel while fishing.
