Precision CNC Engineering. Lightweight Wide-Ratio Speed.

The engineering hallmark of the Alugear Nova34 is its hybrid monoblock CNC construction and optimized shift-ramp architecture. Designed for maximum strength-to-weight efficiency, the upper climbing cogs are precision-milled from a single block of high-strength 7075-T6 aluminum alloy, while the smaller high-speed cogs are machined from durable heat-treated steel. Featuring custom-milled shifting ramps and tooth profiles, the Nova34 ensures instantaneous, quiet chain movement across electronic and mechanical 12-speed setups.

Why the Alugear Nova34 Belongs on Your Wheelset:

Hybrid Monoblock Construction: Combines a lightweight 7075-T6 aluminum upper carrier structure with resilient steel lower cogs for maximum weight savings and long-term gear durability.
Versatile 11–34T Wide Gear Range: $11\text{-}12\text{-}13\text{-}14\text{-}15\text{-}17\text{-}19\text{-}21\text{-}24\text{-}27\text{-}30\text{-}34\text{T}$ cadence steps provide tight gaps on flat roads with an easy $34\text{T}$ bail-out cog for steeper climbs.
Optimized Shifting Ramps: Precision 3D-machined tooth profiles align perfectly with 12Speed chains, ensuring crisp, positive gear engagement under heavy torque.
Significant Weight Reduction: Drastically reduces rotating weight at the rear hub compared to standard OEM cassettes, improving rear wheel acceleration and suspension/frame responsiveness.
High-Precision Anodized Finish: Anodized structural coating protects against corrosion and environmental wear while giving your rear wheel an exotic, custom aesthetic.

The Alegro Perspective: Alugear always impresses us with their machining tolerances and attention to detail. Upgrading to the Nova34 cassette is one of the easiest ways to shave significant weight off your wheelset without giving up the wide gear range you need for steep gravel grinds. The shift ramps are clean and quiet under load, and the two-tone alloy/steel construction gives your drivetrain a ultra-clean, boutique look that stock cassettes just can't match.
