What Does ZL-Carbon Add to the Innerforce Platform?

ZL-Carbon fiber is stiffer and lighter than Arylate-Carbon, and those properties create a distinctly different blade at the same speed rating. The Harimoto Innerforce ZLC matches the Harimoto Innerforce ALC at 8.5/10 speed but weighs only 84g, making it one of the lightest composite blades in Butterfly’s catalog. That 3g difference shifts the balance point closer to the handle, and players who use wrist-heavy serving techniques notice the faster racket head acceleration.

The control rating drops from 8.0/10 (ALC) to 7.5/10 because ZL-Carbon transmits energy more abruptly. Contact feels crisper and shorter. Loops still arc because the inner fiber placement preserves the dwell time that defines the Innerforce series, but the ball leaves the blade faster after peak flex. Players who time their strokes precisely gain explosive spin. Those who rely on the blade’s forgiveness during off-center hits find less margin here than with the ALC version.

At $270, the Harimoto Innerforce ZLC sits between the ALC at $185 and the Harimoto Innerforce Super ALC at $250. Players upgrading from the ALC who want more crispness without sacrificing the inner-fiber feel find this blade occupies a specific niche that no other Butterfly model fills.

Rubber Pairing and Playing Style

The 84g weight makes rubber selection impactful on overall racket balance. Tenergy 05 on both sides creates a total racket weight around 175-180g, which is light enough for quick transitions between forehand and backhand. Adding DHS Hurricane 3 on the forehand pushes the total above 185g and shifts balance toward the head, suiting players who commit fully to forehand loops.

The Viscaria at $150-190 delivers more raw speed (9.0/10) with outer fiber placement and heavier weight (87g). Players choosing between the Viscaria and the Harimoto Innerforce ZLC are deciding between direct power and spin-oriented control. Both are advanced blades, but they reward different stroke mechanics.
