Don't worry – if your reel is not on the compatibility list, that doesn't necessarily mean our knobs won't fit. Many manufacturers use the same knob mounts across several model generations.

With a few simple steps, you can check yourself whether our knobs fit your fishing reel.

Step 1 – Can the knob be removed at all?

First, take a closer look at the handle knob of your reel. On most reels, there is a small cap on top of the knob.

This cap can usually be carefully removed:

• pried off gently with a small screwdriver
• or pulled out with a fine needle

Under this cap, you will usually find the screw that attaches the knob to the handle.

Step 2 – Screw or rivet?

Now it gets interesting. Under the cap, you will see either:

• a screw → perfect, the knob can be easily replaced
• no screw → the knob is riveted

Riveted knobs are usually found only on very inexpensive reels and generally cannot be easily replaced.

Step 3 – Unscrew the knob

If there is a screw, you can simply loosen it with a small screwdriver. Then the knob can be pulled off the handle.

Step 4 – Measure the shaft

Now measure the shaft of the handle where the knob sits.

For our knobs, the dimensions should be approximately:

• Diameter: about 4 mm
• Maximum length: about 27.5 mm

If these dimensions fit, you can usually install our knobs without any problems.

See image

Here you can see exactly where to measure.

The right crank knob (knob) significantly influences the grip feel, control, and comfort while fishing. Depending on the fishing technique, reel size, and personal preference, a different knob may be more suitable.

Knob size is usually specified by the diameter at the thickest point – not by the length. This diameter determines how much contact area your hand has with the knob.

Knob Size – The Contact Point to the Reel

18–20 mm – BFS & Ultralight

• Very direct grip feel
• High control with light lures
• Ideal for BFS reels and ultralight setups
• Perfect for precise fishing

Typical use: BFS, finesse, ultralight baitcasters

21–24 mm – Allround

• Good mix of comfort and control
• Very versatile
• Comfortable even during longer fishing sessions

Typical use: allround baitcasters, zander, perch, pike

25–27 mm – Large Grip

• More grip surface
• Better control with higher resistance
• Comfortable when fighting larger fish

Typical use: pike, larger lures, stronger reels

30–40 mm – Bigbait & Saltwater

• Very large grip surface
• Maximum control with high lure resistance
• Relieves hand and forearm

Typical use: bigbait, large swimbaits, saltwater

Important Note on Knob Size

Basically, larger knobs can also be mounted on smaller reels as long as the fitting matches. Technically, this is often possible.

However, you should pay attention to choosing a knob size that makes sense for the reel. A very large or heavy knob can significantly accelerate the crank due to its own weight and the resulting centrifugal force, more than some light reels are designed for.

Especially with very light baitcaster reels, BFS reels, or finely built gearboxes, a knob that is too large can increase the load on the mechanism. In the worst case, this can lead to more wear or even damage to the gearbox over time.

Therefore: just because a knob can be mounted does not automatically make it the best choice for the respective setup. For small and light reels, it is advisable to opt for light and appropriately sized knobs.

Knob Material – Differences in Grip Feel

EVA

• Very light
• Non-slip
• Water-resistant
• Very comfortable for fishing

Rubber

• Very high grip
• Very controllable when wet
• Comfortable during the fight

Silicone

• Very soft and grippy
• Pleasant surface
• Very comfortable for longer sessions

TPE (Thermoplastic Elastomer)

• Soft, pleasant surface
• Very good damping
• High comfort

Cork

• Natural grip feel
• Very light
• Warm in the hand
• Classic look

Wood

• Very individual appearance
• Natural feeling
• Slightly firmer than EVA or TPE

Carbon

• Extremely light
• Modern design
• Very direct feedback

Aluminum

• Very robust
• Precisely CNC machined
• Cool, direct grip feel
• Very durable

The Right Knob Size for Your Setup

Here is a quick guide to which size fits which setup:

• BFS & Ultralight: 18–20 mm
• Allround Baitcaster: 21–24 mm
• Large Lures / Pike: 25–27 mm
• Bigbait & Saltwater: 30–40 mm

Ultimately, choosing the right knob is always a matter of personal grip feel. Many anglers prefer larger knobs for more comfort, while smaller knobs offer more direct feedback from the reel.
