Winner Rainbow Premium (Libre)

Cone core 20&10
Technical Construction

A hybrid laminated core combining 20-slice and 10-slice structures, with the upper 7 segments built from 20-slice maple and the lower 3 from 10-slice hardwood. This inner cone-shaped core ensures near-perfect mechanical stability.

- Powerful energy transfer with exceptional rebound consistency.

- Optimized full-cue balance.

- Long-lasting straightness and durability.

New generation
2-Stage Wood Joint

The new-generation 2-stage wood joint enables assembly and disassembly twice as fast as traditional wood joints. Larger thread depth increases durability, while the joint connects the shaft and butt into a seamless unit — delivering a smooth, effortless stroke ideal for libre play.

Screw-in Rubber Bumper
0.7-turn quick release

Modern 5-rounded-side shape, inspired by the Five Elements. The curved edges offer a secure and comfortable grip during removal and attachment.

- Integrated threaded hole allows precise weight customization.

- Center-engraved K logo reflects our inner mindfulness — crafted with care from the core to every visible detail.

20-Slice Premium Shaft
Bone Grain

This Libre 20-Slice Premium Shaft features individually selected bone-grain slices, crafted exclusively for the Premium line. Elite performance meets professional aesthetics — power and precision, right from the first glance.

GABA Technology

GABA is the result of years of refinement — enhancing the Libre 20-Slice Premium Shaft with superior deflection reduction and optimal, flexible power transmission. Now, you can confidently execute high-spin shots with greater accuracy and more precise cue ball paths.

Hollow-Core Shaft

Introduced in January 2021, the hollow-core technology significantly reduces the stiffness often found in laminated shafts, creating internal flexibility that enhances cue ball rebound. The foam-filled hollow core dampens vibrations and minimizes hollow sound feedback, delivering a smoother, quieter, and more responsive stroke.

20 Premium Hard Maple Slices – Canada

Crafted from 20 premium slices of Canadian hard maple, each with a distinct grain pattern. The 18-degree slices are CNC-cut with high precision. Every slice undergoes strict quality control to ensure straightness, durability, consistent weight, and visual aesthetics. All unstable or low-grade wood blanks are completely eliminated.

Independent Radial Compression

The 20 slices are carefully arranged based on a scientific layout to ensure maximum stability and performance. They are then pressed using an independent radial compression system, where force is applied uniformly to each slice. This process runs continuously for a minimum of 8 hours to ensure the adhesive fully cures. After pressing, the laminated shaft blank undergoes extended evaluation to verify quality before becoming a finished product.

Optimized Taper Design

The Libre 20-Slice Premium Shaft features a slim taper shaped to match the wood’s stiffness, slice count, energy delivery, and playing feel.
