Elevn Flat Mount Adapter Kit 120mm – 10mm Chase RSP 5.0

Overview

The Elevn Flat Mount Adapter Kit is a disc brake mounting system engineered exclusively for Chase RSP 5.0 frames with 10mm rear axles. This kit provides everything needed to install flat-mount mechanical or hydraulic disc brakes, including a CNC-machined aluminum adapter, 120mm ISO-mount rotor, spacers, and mounting hardware.

Key Features

• Frame-Specific Design — Engineered exclusively for Chase RSP 5.0 frames; ensures precise fit and optimal brake geometry without modifications or adapters
• 10mm Axle Compatibility — Designed for frames with 10mm rear axle spacing; maintains proper brake caliper alignment and modulation
• Flat-Mount Standard — Compatible with all standard flat-mount mechanical and hydraulic disc brake calipers; allows flexibility in brake system selection
• CNC Machined 6061-T6 Aluminum — Precision-machined aerospace-grade aluminum ensures consistent bore diameter and caliper support; improves rotational smoothness and component longevity
• 120mm ISO-Mount Rotor Included — Pre-sized 120mm disc rotor with ISO 6-bolt mounting system included; ready-to-install without additional purchases
• Rotor Optimization — Adapter optimized for both 120mm and 140mm diameter rotors; allows future upgrade to larger rotor if desired (rotor purchased separately)
• Precision Spacer System — Includes 1mm and 0.5mm spacers for fine-tuning rotor clearance and brake caliper alignment; eliminates rubbing and ensures smooth operation
• Complete Mounting Hardware — Disc bolts and all necessary fasteners included for straightforward installation

Compatibility & Ideal Use Cases

Compatible exclusively with Chase RSP 5.0 frames featuring 10mm rear axle spacing; not compatible with other frame models or axle sizes. Requires a separate flat-mount disc brake caliper (mechanical or hydraulic); brake system not included in kit. The frame-specific design eliminates need for additional adapters or modifications, ensuring optimal brake performance and geometry. Ideal for Chase RSP 5.0 owners upgrading from coaster brakes or adding disc braking capability. The included 120mm rotor and spacers provide immediate installation capability; larger 140mm rotors can be added later if increased stopping power is desired. Essential component for riders prioritizing flat-mount disc braking on Chase RSP 5.0 frames. Not suitable for other frame brands or models. Purchase of a compatible flat-mount disc brake caliper is required for complete system functionality.
