Description
Specifications

Upgrade your bike's drivetrain with the Prestacycle UniBlock PRO Cassette - an unbeatable choice for 11-speed systems requiring HG12 interface compatibility. Crafted for serious cyclists, this high-performance cassette combines innovative engineering with durable materials to deliver superior shifting, enhanced efficiency, and long-lasting reliability.

Materials & Construction:

The UniBlock PRO Cassette is machined from a single solid block of cold-forged Chrome Molybdenum alloy steel, known for its exceptional strength and fatigue resistance. After machining, it undergoes a meticulous heat-treatment process, tumble-finishing, and electroplating-ensuring superior durability, corrosion resistance, and low-friction operation. The precise manufacturing process guarantees a high-quality, lightweight component, weighing only 219 grams.

Performance & Engineering:

Equipped with ARC (Advanced Radial Curve ) shifting tooth profile technology, the cassette guarantees the fastest, smoothest, and most reliable gear changes across all cogs. ARC design optimizes each tooth pairing for perfect engagement under load, reducing shift times and minimizing power loss. The single block structure not only enhances strength but also distributes forces evenly, reducing torsional stress and wear on the freehub, and delivering longer equipment life.

Components & Technology:

Featuring a versatile HG12 interface, the UniBlock PRO cassette is compatible with all HG12, HG11, and HG10 freehubs-making it ideal for most modern road and mountain bike setups. The wider inner and outer freehub teeth engagement enhances contact area, ensuring crisp, secure shifts even under high torque. Included with the cassette is a striking red anodized locknut compatible with HG12 and HG11 freehub bodies; HG10 users will need to purchase the compatible Prestacycle HG10 lockring separately.

Style & Use Case:

Designed in sleek silver, the UniBlock PRO cassette seamlessly integrates with high-performance bikes, whether you're tackling competitive racing, endurance rides, or gravel adventures. Its wide-range 11-30t gearing provides excellent versatility for climbing steep hills and maintaining speed on flat terrain. This durable, lightweight cassette is perfect for riders seeking precise, rapid shifting and reliable performance in demanding conditions.

Innovative & Differentiating Features:

- Machined from a single, cold-forged Chrome Molybdenum alloy steel block for exceptional strength and longevity

- ARC shifting tooth profile technology for lightning-fast, smooth gear changes under load

- Compatible with all HG12, HG11, and HG10 freehubs, offering broad system versatility

- Ultra-lightweight design optimized by removing unnecessary material without compromising strength

- Increased freehub engagement due to wider contact points, improving efficiency and power transfer

- Polished, electroplated surface for reduced friction and corrosion resistance
