ALUGEAR 104 BCD ROUND AERO (T-TYPE) MTB CHAINRING

*PRODUCT IS BLACK ONLY!!!

Upgrade your drivetrain with the original design ALUGEAR AERO 104 BCD Round Chainring. Specially engineered for peak mechanical efficiency and structural stiffness, this premium chainring is fully optimized for the latest generation of mountain bike drivetrains, including SRAM T-Type systems. CNC machined from aerospace-grade 7075-T6 aluminum and protected by a hard-coat industrial anodized finish, it delivers an ultra-lightweight setup without sacrificing durability, chain retention, or smooth mud-shedding performance.

Key Features

• Advanced Narrow-Wide Tooth Profile: Designed with alternating narrow and wide teeth matched perfectly to modern bicycle chains to ensure flawless chain security, eliminate noise, and significantly decrease overall system wear.
• SRAM T-Type & Multichain Compatibility: Engineered with premium universal teeth geometries that run quietly and seamlessly across SRAM 11-speed, 12-speed Eagle, and 12-speed T-Type Transmission systems, alongside Shimano 11-speed, 12-speed Hyperglide+ (HG+), and KMC chains.
• Superior Mud Self-Cleaning: Optimized mud-shedding recess areas built into the tooth clusters guarantee reliable engagement, quiet operation, and smooth drivetrain performance even on the messiest, wettest trail conditions.
• Premium CNC-Milled Craftsmanship: Fully CNC machined from high-strength 7075-T6 aluminum alloy and finished with an industrial hard anodizing process for enhanced impact protection, structural resilience, and a premium long-lasting finish.
• PowerMeter Ready Setup: Form-fitted for seamless integration on 4-bolt 104mm BCD spiders, specifically optimized for SRAM Quarq PowerMeter spiders.

Installation & Maintenance Recommendations

• Mounting Hardware: Requires 4 sets of 5mm mounting nuts paired with 6.5mm length chainring bolts.
• Tool & Torque Requirements: Use a 6mm hex socket for the nut and a 5mm hexagon socket for the bolt. Do not exceed a maximum permissible torque threshold of 10 Nm.
• Chain Retention: For optimal security on aggressive single-ring configurations, we highly recommend utilizing a rear derailleur equipped with an active, high-tension clutch system.
• Best Practice: To avoid irregular engagement wear patterns and maximize power transfer efficiency, it is best to pair your new ALUGEAR chainring with a brand-new, freshly lubricated bicycle chain.
