Description

The PARK TOOL 761S Head Tube Reamer (42.0 mm) is used with the HTR-1 or HTR-1B head tube reaming and facing set to ream head tubes that use the IS42 integrated headset standard, also known as the Campagnolo® Hiddenset standard (42 mm bearing with a 45° contact angle). FSA® and other manufacturers also offer headsets using this standard.

The set includes a spacer (ref. 755), allowing deeper cuts in lower IS42 head tubes.

Sized according to the SHIS designation for IS42 head tubes (upper and lower), with an outside diameter of 42.0 mm.

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

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