Spro Onyx 4000 Free Baitrunner Reel 90cm 480g 4.6:1

Spro Onyx 4000 Free — Reliable Baitrunner Reel for Carp and Coarse Fishing

The Spro Onyx 4000 Free is a capable baitrunner (free-spool) reel built for anglers who target carp and other coarse species with bottom rigs. Solid construction meets a precise freespool system at a practical price point.

Precisely Adjustable Freespool for Confident Bite Detection

The adjustable baitrunner function lets a running fish take line without resistance, then a single turn of the handle re-engages the main drag instantly. Combined with the Quick Drag system, you can set the fighting drag exactly where you need it — essential when a big carp picks up a hair rig and bolts.

Built to Handle Hard-Fighting Fish

The graphite body and rotor keep weight manageable at 480 g while the zinc-alloy gearset, iron main shaft, and aluminium handle arm provide the durability needed for prolonged sessions. The oversized drag knob and large handle make quick adjustments easy even with wet or cold hands. A 4.6:1 gear ratio with 90 cm of line retrieve per turn gives enough speed to recover line without sacrificing control during the fight.

Choose the Right Variant

The Spro Onyx 4000 Free is currently the only listed size in the Onyx Free range. The size 4000 is well suited to carp, bream, tench, and barbel fishing with lines around 0.40 mm (120 m capacity), used with method, bolt rig, or running leger setups on rivers, lakes, and gravel pits.
