Elevn Disc Kit 120mm Rotor – Chase Act 1.2 and 1.0 (10mm Axle)

Product Overview

The Elevn Disc Kit is a complete mechanical disc brake mounting system designed for Chase Act 1.2 and 1.0 frames with 10mm rear axles. This kit provides all necessary hardware to install a 120mm ISO disc rotor setup, including a CNC-machined adaptor, integrated chain adjuster, rotor, fasteners, and cosmetic covers. It accommodates both standard and Center Lock hub designs without additional modifications.

Key Features

• Frame-specific engineering – CNC-machined adaptor and chain adjuster precisely calibrated for Chase Act frame geometry; ensures proper rotor alignment and wheel centering without shimming or adjustments
• Integrated chain adjuster – Left-side chain tensioner built into the brake mount assembly; eliminates need for separate derailleur hangers and maintains consistent chainline geometry
• Anti-rotation locking system – Shelter design and anchor bolt prevent adapter creep and rotor movement under braking load; ensures stable, predictable performance
• Complete hardware package – Includes 120mm rotor, six mounting bolts, washers, spacers, security covers, and all fasteners; ready-to-install without additional parts sourcing
• Dual cosmetic cover options – Two sets of pivot bolt covers (Black and Polished) allow frame-matching aesthetics while concealing standard brake mount points
• Rotor spacers included – Two 0.5mm spacers accommodate different Center Lock and ISO hub designs for proper rotor clearance
• 120mm rotor specification – Lightweight, low-heat output rotor ideal for smaller frames and riders prioritizing maneuverability over maximum braking power
• Center Lock compatibility – Works with Center Lock hubs when used with appropriate Center Lock adaptor

Technical Specifications

• Rotor diameter: 120mm ISO 6-bolt
• Rotor weight: 87g (without bolts)
• Rear axle compatibility: 10mm (standard dropout or thru-axle)
• Frame compatibility: Chase Act 1.0 and Chase Act 1.2 (primary design); may fit other frame brands but not guaranteed
• Adaptor material: Full CNC-machined aluminum alloy
• Chain adjuster: Left-side integrated; includes locking anchor bolt
• Rotor finish: Silver anodized with air vents
• Included fasteners: 6 disc rotor bolts, washers, 2 rotor spacers (0.5mm each), 2 sets pivot covers (Black and Polished)
• Hub compatibility: Center Lock hubs (with Center Lock adaptor); standard ISO 6-bolt hubs
• Estimated weight: Rotor 87g + adaptor and hardware ~200–220g estimated

Compatibility and Ideal Use Cases

• Frame requirement: Chase Act 1.0 or Chase Act 1.2 with 10mm rear axle (primary compatibility); may work on other brands but not tested or guaranteed
• Rear axle: 10mm standard dropout or thru-axle
• Brake caliper: Requires separate mechanical or hydraulic disc brake caliper (not included); must be ISO-mount compatible
• Hub type: Center Lock hubs (with adaptor) or standard ISO 6-bolt hubs
• Larger rotor upgrade: 140mm disc adaptor sold separately if you need increased braking power
• Best for: Chase Act frame owners upgrading to disc braking, lightweight builds, flat to moderate terrain, and riders seeking integrated chain adjustment with brake mounting
• Installation: Requires mechanical skill; alignment critical—follow frame and brake manufacturer torque specifications for all fasteners
• Note: Brake caliper, brake lines/cables, and brake lever sold separately; confirm your brake system compatibility and frame model before purchase
