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 ACROS AH-49 Headset Lower Part features the high-end bearing and seal technologies from ACROS in stainless quality for 1 1/8" steerers.
Precisely manufactured angular contact bearings made of stainless steel form the heart of the AH-49 and offer play-free and smooth steering characteristics for a long time. The right sealing technology is equally important as the highest quality bearings when it comes to high-end components.
VULCANIZED SEALING
New for the year 2017 is a sturdy vulcanized seal bonded to the compression ring and the base plate as an additional and first barrier against water and dirt.
V-LIP
In addition to the new vulcanized seal on the compression ring and the base plate, the sealing discs of the bearings now have a special v-groove double split lip (V-LIP). Furthermore, the V-LIP is recessed in a fine polished groove, which significantly increases the sealing effect once again.
