I9's Solix hub offers 605 points of contact and .59° of engagement, optimized for lower rolling resistance and weight saving with updated features like lighter leaf strings and different seals.
The UL300 wheels provide excellent ride quality, similar performance to the higher-engagement Hydra hub, lightweight design, but come at a premium price of $2,395 for the wheelset and $695 for the Solix hubs.
The Solix hubs have been optimized for lower rolling resistance and weight savings through lighter components, quieter freehub buzz, updated seals, bearing preload, and machining for reduced hub body weight.
