XLC have created the A-Head Semi Headset HS-I12-1 for those who require supremely smooth steering with reliable components. Manufactured specifically for bikes with 1 1/8” high rise conical steerer tubes, and with an aluminium construction for the ultimate in lightweight strength. CroMo semi cartridge bearings are used to optimise steering. CroMo cartridge bearings mean you’ll need less frequent servicing to keep your headset running smooth. If they need replacing you simply switch out the single unit rather than individual ball bearings. Aluminium cups are also used. The dimensions of the HS-I12-1 are 28.6/44/30mm and the height is 15.6mm.Hoogte: 17.9+2.5=20.4mmBegrenst tot mogelijk 60°met stuuruitslagbegrenzing (stuurbereik tot 60° mogelijk)tapered7-deligXLC Artikelnummer: 2500509000 EAN-code: 4055149095987 Leveranciersnummer: 2500509000 Winkelverpakking: Yes
