XLC HS-I09 Aheadset ZS 44/28,6 | ZS 44/30

The XLC Comp A-Head Headset HS-I09 is a semi-integrated A-Head headset with CroMo bearing shell and aluminium body. It is engineered to provide the sort of steady predictable steering you want from your trusty bicycle, with compatibility with 1.1/8” (28.6 mm) steerer tubes.

The headset uses ball bearings for smooth movement but this means it will need maintenance more often than some of XLC's other cartridge-bearing headsets.The height of the headset is a combined 15.6 mm with the top accounting for 10.1 mm of that and the bottom measuring 5.5 mm. It is compatible with a frame diameter of 44 mm.
