Primo N4FL V2 Front Hub
The Primo N4FL V2 front hub uses a flangeless 6000 series aluminum hub shell featuring press-fit alloy hardware with integrated plastic hub guards that are designed to protect the spokes from possible grind damage. The hub spins on two sealed cartridge bearings and a newly improved chromoly center axle with 3/8"x24tpi axle bolts for an overall increase in strength. Note: Uses conventional J-bend spokes in a "heads in" lacing pattern.
