To maximize the compatibility with different fork steerers, bikes and frames, the upper and lower parts of ACROS headsets are being offered separately in a great variety of dimensions.
The integrated ACROS Ai-42 Headset Lower Part features the established seal technologies from ACROS and high-end bearings in stainless quality.
Precisely manufactured angular contact bearings made of stainless steel form the heart of the Ai-42 and offer play-free and smooth steering characteristics for a long time.
The name ACROS Ai-42 describes the integrated (also known as drop in) 1 1/8" Ahead headset for frames with a 42 mm headtube. The S.H.I.S. denotation (see attachment) of the lower part offered here is IS42/30.
