Weighing only 54 feathery grams, the Kinetix Neutron is the lightest production hub on the market. The Neutron is made to our 74mm compact dimensions for optimal strength and bracing angles when paired with 16” and 20” rims. The patented design places the cartridge bearings as close as possible to the point of loading at the fork ends for improved strength and durability. Flanges are a beefy 4mm thick, to take the stresses of high spoke tensions and radial lacing.
