Avail Shimano 21 SLX BFS Microcast Spool
Avail Microcast Spool for Shimano 21 SLX BFS – Your upgrade for ultralight casts!
🎣 For finesse fanatics & precision freaks!
Welcome to the Champions League of Bait Finesse Performance! 🚀 With the Avail Microcast Spool, you transform your Shimano 21 SLX BFS & 17 Scorpion BFS into a high-precision machine for light lures and perfect casts.
What does it bring you? Buttery smooth casts with light jigs, weightless rigs, or finesse setups – no jerks, no "Come on, fly already!" frustration. This spool simply makes your life better.
🔧 Two spool depths – choose your setup!
✔ 21SLX15R (1.5 mm spool depth) – Ideal for 4-6 lb fluorocarbon or PE lines
💡 Perfect for: Drop shot, Neko rig, ultralight hardbaits
✔ 21SLX29R (2.9 mm spool depth) – For 10-12 lb lines & slightly heavier rigs
💡 Perfect for: Texas rigs (3.5-9 g), small jigs, chatterbaits
➡️ In short: The flatter the spool, the lighter the line and finer the tackle. The deeper the spool, the more line capacity for all-round setups.

🔧 Installation & important tips
🛠 Additional magnets recommended for model 21SLX15R!
- Due to the flat design, the drag sits further away, which leads to less drag effect.
- Solution? Simply add 4 x 1 mm magnets (up to 8 pieces, sold separately) onto the existing ones – and your finesse dream setup is ready!
⚠ Avoid "thumbing" on the spool edge!
- Pressing directly on the edge can damage the anodizing.
- Instead, always stop on the winding surface!
⚠ Spool line with care!
- Especially do not wind too tight with nylon – otherwise, unsightly pressure marks will appear.
⚠ Check & oil ball bearings!
- Factory treated with rust protection grease – degrease & lightly oil before first use for perfect performance!
