Head assembly with forged and CNC machined duralumin bowls designed for:
• frame with an inner diameter of the head tube 34mm
• 1-1 / 8 "fork post
Upper and lower bearing MR117 with ceramic balls.
The main advantages of FSA ceramic bearings compared to standard bearings are their longer life, lower weight, higher strength, lower rolling resistance and excellent anti-corrosion properties.
The bearings contain high-precision ceramic balls made of silicon nitride (Si3N4) with an accuracy of class 5, ie only with a deviation of 5 / 1,000,000 "from the ideal spherical surface.
Their weight is about 60% lower, while they are 7 times stronger compared to steel balls.
The bearing tracks are made of high-carbon chrome steel 52100.
The NBR 70 seal used minimizes friction and protects the bearing from dirt.
The package contains an FSA hedgehog for a 1-1 / 8 "metal fork post.
Stack height outside the frame (stack height): 29.7mm
Weight 100g.
