Verdict: The Performance MK II is the new mid-range benchmark, offering more stiffness than the MK II and significantly greater accessibility than the Performance-X. It's an allround performer across all demanding disciplines. This is the perfect choice for upgrading to a performance mast without committing to an ultra-specialist model.
DETAILED DESCRIPTION
The New Armstrong Benchmark
Armstrong sets the Performance MK II as the new benchmark in its lineup. This is a stiffer evolution of the Performance MK I, featuring a completely re-engineered section. The mast's profile now measures 13.8 mm in thickness (compared to 15.8 mm on the entry-level MK II and 12 mm on the specialist Performance-X), with a refined chord of 114 mm. This design delivers a more hydrodynamically efficient profile, capable of excelling across all demanding foil disciplines. Advanced riders will find this mast underfoot in most conditions, offering both stiffness and versatility without compromise.
+30% Flex Stiffness, +20% Torsional Stiffness
The figures released by Armstrong are crystal clear: a +30% increase in flex stiffness and +20% in torsional stiffness compared to the Performance MK I. What does this mean for you? More precise feedback underfoot, unwavering confidence at high speeds, and a mast that holds its line without bending in loaded turns. The Performance MK II delivers fine, clear control, making it an excellent choice for advanced riders who demand direct water feedback.
Integrated 0.5° Geometry and A+ System
Just like the Performance-X, the Performance MK II comes with a pre-integrated 0.5° mast angle, and it includes a 0.5° mast shim for fine-tuning. This pre-calculated geometry optimizes the foil's hydrodynamic efficiency. It means you won't need extra shims to achieve the ideal trim. The 114 mm chord ensures perfect geometric compatibility with A+ Front Wings and fuselages. Your wings will maintain the same angle range as with other Armstrong Performance masts. The mast assembles without an adapter on all wings, fuselages, and boards in the current A+ Armstrong range.
The Do-It-All Carbon Mast
Armstrong describes the Performance MK II as the mast that truly does it all: excelling in downwind, freestyle, and powerful turns. It's the promise of a high-end allround mast, perfectly suited for an advanced rider who frequently switches between disciplines. The screw set is consistent with the rest of the range, including 3 M6 28.5 mm screws and 5 M7 26 mm screws in 316L stainless steel with a Rainbow Titanium coating, 5 M7 T-nuts, 1 8 mm titanium barrel nut, and a Torx T30 key. A protective bag is also included.

ARMSTRONG PERFORMANCE MK2
The Performance MK2 (13.8 mm profile) is Hydro Gav's top pick, offering the best versatility-to-price ratio in the Armstrong range. It provides more stiffness and support than the Carbon MK2, without the flagship price tag. He's so impressed, he's even torn between it and the Performance-X.

FAQ - ARMSTRONG PERFORMANCE MK II CARBON MAST
The MK II is your entry point to carbon masts, featuring a 15.8 mm profile and 116 mm chord for accessible versatility. The Performance MK II is the mid-range do-it-all mast, boasting a 13.8 mm profile, +30% stiffness, and a 0.5° angle, making it ideal for advanced to expert riders. For those who demand maximum performance from their foil, the Performance-X is the specialist for speed and pure glide, with its 12 mm profile and UHM carbon construction.
Yes, if your foil uses the Armstrong A+ system. The Performance MK II utilizes the standard A+ connection, allowing for seamless assembly without an adapter to all current A+ range Front Wings, fuselages, and boards. Simply verify that your setup is A+ and not the older V1 system.
The 72.5 cm mast offers the standard speed and handling compromise for most conditions. Step up to the 79.5 cm for added clearance in chop. The 86.5 cm is perfectly suited for downwind runs and more challenging conditions. The 93.5 cm is reserved for long-distance pumping and expansive bodies of water where flight height becomes a significant asset. For maximum responsiveness, always opt for the shortest length compatible with your riding style.
The 0.5° mast shim is a wedge designed to be inserted between the mast and the board, allowing you to finely adjust your foil's pitch. Armstrong includes the shim that corresponds to the nominal geometry of the Performance MK II (0.5° angle). This ensures you can restore the pitch for which the mast was designed, or make slight adjustments to the pitch based on the board you're using.
In practice, this translates to more precise feedback underfoot and significantly greater confidence at high speeds. The mast exhibits less flex in loaded turns, resulting in a more stable trajectory and healthier behavior under heavy load, whether you're tackling downwind runs, executing freestyle maneuvers, or carving powerful turns. For any rider pushing their foil to the limit, this is a genuine gain in control.
