DT-5.2 Disc Brake Mount Facing Tool

The tight tolerances of modern bicycle disc brake systems require precise alignment of all components in order to ensure proper performance, and yet the brake mounts on many bike frames and forks are often misaligned. The Park Tool DT-5.2 is a precision tool system engineered to accurately face disc brake mounts so they are perfectly aligned to the rotor. The DT-5.2 faces any IS mount, post mount, or flat mount-style brake mounts, including low-clearance chainstay mounts. The included telescoping axle adaptors allow use with any configuration of open or thru-axle dropouts and dropout widths (including Boost 110, Boost 148 and all fat bike axles). A professional solution for an essential frame prep procedure.

• The Park Tool DT-5.2 is engineered and built to accurately face front or rear disc brake mounts so they are precisely aligned to the rotor
• Use of the DT-5.2 helps ensure proper disc brake setup and performance
• Faces any IS Mount, Post Mount or new Shimano
• ®
• Flat Mount, including low clearance, chainstay mounts
• Telescoping axle adapters allow use with any configuration of open or thru axle dropouts and dropout widths (including Boost 110, Boost 148 and all fat bike axles)
• Precision machined parts
• Includes two facing cutters--one for IS mounts and one for Post and Flat Mounts

NOTE: Although Park Tool facers, reamers, cutters and dies are compatible with most frame materials currently used in the bicycle industry, high performance materials such as carbon fiber and titanium can dull these frame prep tools at a much faster rate than steel or aluminium. Use of the 2197 Diamond Abrasive Adapter is recommended for carbon fiber brake mounts.
