SILCA Secret Chain Blend + SpeedChip – Race Optimised Hot Wax

When outright speed matters, this is the wax setup.

SILCA Secret Chain Blend with SpeedChip takes SILCA’s premium hot-melt chain wax and tunes it specifically toward maximum drivetrain efficiency.

Secret Chain Blend uses a specialised four-wax formulation combined with multiple sizes of tungsten disulfide (WS₂) particles to deliver a fast, clean and highly efficient waxed drivetrain.

Adding SILCA SpeedChip pushes the blend further toward outright speed.

According to SILCA, adding one SpeedChip per 250g of wax can improve chain efficiency by approximately 0.4%, while two SpeedChips per 250g can improve efficiency by up to 0.6% compared with standard Secret Chain Blend. The trade-off is reduced lubrication intervals compared with the standard formulation — exactly the compromise you’d expect from a wax optimised specifically for racing.

Why choose the SpeedChip blend?

• Race-focused drivetrain efficiency
• SILCA claims up to 0.6% efficiency improvement depending on SpeedChip concentration
• Tungsten disulfide friction modifiers

SILCA says SpeedChip has been used by Visma | Lease a Bike for time trials and one-day classics, and describes it as its choice when maximum speed is the priority.
