Measure Baitcaster Crankshaft Yourself
FAQ: Which shaft bore (7×4 mm / 8×5 mm) do I need for my baitcaster reel handle?
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.
What you need
- Caliper (digital or analog). In a pinch, a ruler will do – but a caliper is much more accurate.
- Optional: a cloth to prevent small parts from rolling away (ball bearings love adventures).
How to measure correctly (in 60 seconds)
- Remove the handle: Remove the cap, loosen the locknut/screw, and pull off the handle.
- Important: Do not measure the nut/locknut, but the crankshaft (shaft) onto which the handle is mounted.
- Measure width (first number): Place the caliper at the widest point of the shaft (usually “flat to flat”) and read the value. This is usually 7 mm or 8 mm.
- Measure height/second side (second number): Rotate the caliper 90° and measure the narrower side. This is usually 4 mm or 5 mm.
-
Assign result:
≈ 7 mm & ≈ 4 mm → you need 7×4 mm
≈ 8 mm & ≈ 5 mm → you need 8×5 mm
Quick check if you’re unsure
- Measure 2–3 times (it’s easy to measure “crooked” once – happens to everyone).
- Values very close? Small deviations (e.g., 7.0–7.2) can be normal depending on the measuring point.
- If it’s not clearly 7×4 or 8×5: take a photo of the shaft + caliper display and contact us.
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.
Guide: Which Baitcaster Reel Handle Suits You?
Which crank fits your setup?
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.
1. The right length – understanding leverage
The length of the crank determines the torque: the longer the crank, the more leverage.
70–85 mm – Compact & direct
Suitable for:
- BFS & Finesse
- Light lures
- Technical lure control (twitching, topwater)
Features:
- Quick response
- Direct feedback
- Ideal for smaller baitcaster reels
90–100 mm – The allround range
Suitable for:
- Jigging
- Crankbaits
- Spinnerbaits
- Universal applications
Features:
- Good balance of power & speed
- Pleasant handling
- Fits most setups
105–120 mm – More leverage, more control
Suitable for:
- Big Baits
- Large hardbaits with strong action
- Pike setups
- 300 size reels and larger
Features:
- Higher torque
- Less effort when reeling in
- Noticeable relief with heavy lures
2. Handle material – weight & stability
Carbon Handle
- Very light
- High stiffness
- Supports a balanced balance
Ideal for weight-optimized or finesse-oriented setups.
Aluminum Handle
- Stable and durable
- Corrosion resistant
- Precisely CNC machined
Aluminum is the versatile standard in baitcaster tuning.
3. Knob size – The contact point to the reel
Knob size is usually given by the diameter at the thickest point.
18–22 mm – Small Knobs
- Very direct feel
- High control with light lures
- Ideal for smaller reels
22–27 mm – Medium Knobs
- Good mix of comfort & control
- For allround applications
- Comfortable for longer sessions
Over 27 mm – Large Knobs
- More grip area
- More control under strong resistance
- Relieves strain in big bait setups
4. Knob material – differences in grip feel
EVA
- Very light
- Non-slip
- Weather resistant
Rubber
- High grip
- Very controllable when wet
- Comfortable during the fight
TPE (Thermoplastic Elastomer)
- Soft, pleasant surface
- Good damping
- High comfort
Cork
- Natural feeling
- Very light
- Warm in the hand
Wood
- Individual look
- Natural feeling
- Slightly firmer than EVA or TPE
Carbon
- Very light
- Modern design
- Direct, firm feedback
Aluminum
- Very robust
- Precisely manufactured
- Cool, direct grip feel
- Especially durable
5. Check compatibility
Before deciding on length or knobs, check the axle bore of your reel:
- Shimano → mostly 7×4 mm
- Daiwa & Abu Garcia → mostly 8×5 mm
If your reel is not listed, you can measure the axle bore yourself with a caliper.
