DT-5.2 Features

  • Faces any IS mount, post mount, or flat mount, including low clearance chainstay mounts
  • 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)
  • Includes two facing cutters:
    • IS mounts
    • post and flat mounts
  • Includes storage case

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 aluminum. Use of the 2197 Diamond Abrasive Adapter is recommended for carbon fiber brake mounts.
