MRP ISCG-05 BB Adapter, Threaded BSA Bottom Bracket Chainguide Mount

MRP ISCG-05 BB Adapter, Threaded BSA Bottom Bracket Chainguide Mount

• UNIVERSAL BB COMPATIBILITY: Enables the installation of modern chain retention systems on frames lacking integrated mounting tabs. This adapter is specifically designed for use with (threaded) BSA bottom bracket shells, mounting securely between the drive-side BB cup and the frame shell.
• ISCG-05 MOUNTING STANDARD: Provides a rock-solid 3-bolt ISCG-05 interface (55.92mm spacing) for your bike. This allows for the seamless addition of the industry’s most popular chainguides and bashguards, including the MRP G5, SXg, and AMg series.
• LOW-PROFILE INTEGRATION: Features a precision-machined profile that sits flush with the face of the BB shell. By replacing a standard 2.5mm BB spacer, it maintains your original chainline while providing the necessary structural support for high-impact drivetrain protection.
• HIGH-STRENGTH ALLOY: Crafted from premium, lightweight aluminum to ensure maximum lateral stiffness and durability. The robust construction is engineered to withstand the rotational forces of a dropped chain and the vertical impacts of a bashguard during aggressive riding.
• PERFECT FOR DIY UPGRADES: Ideal for mountain bikers with "down-country" or older trail frames that didn't come factory-equipped with ISCG tabs. A must-have for performance riders who want to add impact protection and chain security to their existing 1x drivetrain.
