Hydra OS Series S-Glass Crankbait Rod Blanks

Hydra Fishing Components OS Series Crankbait Rod Blanks are 100% S-Glass fishing rod blanks designed for custom rod builders who want the smooth loading characteristics of fiberglass without the excess weight and slower response commonly associated with traditional E-Glass blanks.

Built entirely from S-Glass fiberglass, the OS Series is lighter than comparable E-Glass rod blanks while maintaining the controlled, forgiving action that makes glass an excellent choice for crankbaits and other treble-hook reaction baits. Each blank features a Moderate-Fast action, allowing the rod to load progressively on the cast and absorb sudden changes in pressure during the fight while retaining the recovery and responsiveness serious anglers expect from a modern crankbait rod.

Built for Crankbait and Treble-Hook Fishing

The OS Series was developed for freshwater bass applications targeting Largemouth Bass and Smallmouth Bass. The combination of S-Glass construction and Moderate-Fast action provides the controlled flex needed to keep treble hooks loaded without creating the overly soft or sluggish feel associated with many traditional fiberglass rods.

Depending on the length and power selected, Hydra OS Series blanks are well suited for:

Squarebill crankbaits
Shallow-diving crankbaits
Medium-diving crankbaits
Deep-diving crankbaits
Lipless crankbaits
Treble-hook reaction baits
Other moving-bait techniques where a forgiving Moderate-Fast action is preferred

The progressive loading profile helps maintain consistent pressure on hooked fish, while the increased responsiveness of S-Glass gives anglers better feedback from lure vibration, cover contact, bottom deflection, and changes in crankbait action.

100% S-Glass Construction

S-Glass provides custom rod builders with an alternative to both traditional E-Glass and graphite crankbait blanks. Compared with a similar E-Glass rod blank, the OS Series offers reduced blank weight and a more responsive feel while preserving the fiberglass characteristics many anglers prefer for treble-hook techniques.

These are 100% S-Glass blanks, not graphite/glass composites.

Available Lengths and Powers

The Hydra OS Series is available in six crankbait rod blank configurations:

Medium Heavy

7'0" Medium Heavy / Moderate-Fast
7'3" Medium Heavy / Moderate-Fast
7'6" Medium Heavy / Moderate-Fast

Heavy

7'3" Heavy / Moderate-Fast
7'6" Heavy / Moderate-Fast
7'9" Heavy / Moderate-Fast

This range allows custom rod builders to select the appropriate combination of length and power based on crankbait size, diving depth, casting distance, cover, and personal fishing style.

Matte Black Finish for Custom Rod Builds

Every OS Series blank receives a matte black coating that provides a clean, versatile foundation for custom rod construction. The understated finish pairs easily with cork, EVA, carbon fiber grips, custom reel seats, metallic or standard thread colors, and a wide range of guide finishes.

Hydra Fishing Components Quality

Hydra OS Series S-Glass Crankbait Rod Blanks are manufactured in China to Hydra Fishing Components specifications and inspected in the USA for consistency before being offered to custom rod builders.

Each OS Series blank is backed by a 1-year Hydra Fishing Components warranty.

For custom rod builders looking for a 100% S-Glass crankbait rod blank that is lighter than comparable E-Glass, responsive in hand, Moderate-Fast in action, and purpose-built for bass crankbait fishing, the Hydra OS Series provides a modern fiberglass platform for building high-performance custom crankbait rods.
