Alugear Golf Ball Aero Round 1X (Sram ThreadMount)

Thread Mount Precision. Aero Power-Meter Integration.

The engineering highlight of the ALUGEAR Round 1X AERO Thread Mount Chainring is its thread-mount architecture paired with an aerodynamic solid-face structure. Machined from high-grade 7075-T6 aerospace aluminum, the chainring threads directly into thread-mount Quarq power meter spiders; creating an ultra-stiff, flex-free interface that maximizes wattage transmission while ensuring precise, uncorrupted power data collection. Coupled with Alugear’s specialized narrow-wide tooth profiling, it keeps your chain anchored over rough washboard gravel and high-cadence sprint efforts without requiring an extra chain guide.

Why the Alugear 1X AERO Belongs on Your Crankset:

• Direct Thread-Mount Interface: Screws directly onto threaded Sram AXS / Quarq power meter spiders, yielding superior interface rigidity and eliminating chainring bolt creaks.

• Aerodynamic Solid-Face Profile: Smooth aero shielding minimizes wind turbulence around the spider, helping you hold higher speeds on open flats and high-velocity gravel sectors.

• Specialized 1X Narrow-Wide Tooth Profile: Alternating tooth thickness provides absolute chain retention, ultra-quiet engagement, and efficient mud shedding in dirty riding conditions.

• Aerospace 7075-T6 CNC Construction: Precision-milled from top-tier aluminum alloy and finished with a hard-anodized coating to dramatically reduce tooth wear over high-mileage training seasons.

• Universal 12/13-Speed Chain Compatibility: Engineered to work seamlessly with Sram 12Speed Flattop, T-Type, Eagle, and Shimano 11/12Speed HG+ chain standards.

• Optimized 6.5mm Offset: Delivers an ideal 45mm (standard) or 47.5mm (wide) chainline for smooth gear tracking across the entire width of your rear cassette.

The Alegro Perspective: Thread-mount power meters are the gold standard for clean aesthetics and reliable data, but finding high-quality aftermarket chainrings for them can be tough. Alugear solved this problem with engineering perfection. The Thread Mount AERO chainring eliminates the weight and flex of traditional 4-bolt spider setups, giving you an rock-solid platform for power transfer. Plus, keeping it round ensures your Quarq power meter reads 100% accurate cadence and torque values without the data distortion often caused by oval rings.
