Description

The PARK TOOL 799 Lower Integrated Bearing Reamer (47 mm) is used with the HTR-1 head tube reaming and facing set or HTR-1B to ream lower head tubes using the 1 1/4" (IS47) integrated bearing standard.

This precision reamer cuts a bearing seat at 45 degrees, ensuring a precisely sized fit for the integrated headset on compatible frames.

It is sized to the SHIS specification for IS47 head tubes and has an outer diameter of 47 mm.

⚠️ The 750.2 oversized centring adaptor is essential. Always use a cutting fluid, such as Park Tool CF-2, when machining.

Compatible with HTR-1, HTR-1B and HTR-HS sets.
