The K77 SDM Sonic Reflex is built to deliver genuine Point-7 performance without the premium price tag. Made in Italy and engineered with Sonic Reflex tip boost, it provides quicker response, lighter handling, and consistent power in every condition.

With 77% high-quality carbon and a durable carbon and glass layup, the K77 offers a proven and reliable constant curve that works perfectly across a wide range of SDM sails. Strong, stable, and predictable, it outperforms many no-name masts that claim higher carbon percentages but fail on the water.

Ideal for AC-0, AC-F, and all SDM sail setups, the K77 is the smart choice for riders who want real performance, durability, and value—without compromise.

Save money, not performance.
Affordable. Relentless. Pure Black.
