Sigal Single Pulleys

Simple Pulleys for Roller Speargun - SIGAL

The SiGAL Simple Pulleys are replacement and rigging accessories specifically designed for building and maintaining Roller Speargun band spearguns for spearfishing. Sold as a pair, they are the ideal solution for anyone looking to build or upgrade their Roller Speargun system with reliable quality components at the right value for money.

The Roller Speargun System: Maximum Power Along the Entire Barrel

In traditional band spearguns, the bands work over only part of the Barrel length, limiting overall thrust. The Roller Speargun system, thanks to the pulleys, allows the bands to use the full Barrel stroke, increasing launch power by up to approximately 30% compared to a classic setup. This makes the Roller Speargun particularly suitable for hunting wary, large species such as dentex and pelagic fish.

Technical Specifications

• Pulley outer diameter: 26 mm
• Pulley groove diameter: 20 mm

• Max groove width: 12 mm

• Package: pair (2 pulleys)

Compatibility and Use

The SIGAL simple pulleys are compatible with standard 6 mm pulley axles commonly used in Roller Speargun builds. They integrate perfectly with SIGAL Roller Speargun muzzles for tube spearguns (26 mm and 25.4 mm diameter) and with other Roller Speargun muzzles on the market designed with 6 mm holes for axle housing. Suitable both for DIY Roller Speargun builds and for replacing worn pulleys on already rigged band spearguns.

Simple Pulleys vs Pulleys with Bearings

Compared to versions with glass ball bearings, simple pulleys offer an excellent balance between functionality and low cost, making them ideal for those entering the Roller Speargun world for the first time or for secondary-level setups. For optimal sliding performance and maximum long-term durability, SIGAL also offers a version with ball bearings, available separately.
