Product DescriptionThe Solos headset utilizes very low friction bearings for drag free performance. The large diameter balls (5/32") are larger than those of other headset brands and yield reduced rolling resistance. The bearings also incorporate low drag rubber seals and nylon retainer cages for more efficient bearing movement.
In addition to housing fully sealed stainless steel cartridge bearings, the Solos overhanging cup/cover design keeps contaminants from reaching the bearings. This overhanging "treacherous path" feature is repeated with the lower cup/crown race.
