Princess Boost ULImited front hub

The Princess Boost ULImited hub is the result of the latest research developments performed by Tune. Here are the highlights of this unique hub: a ultra light hubshell made from special Aluminium Alloy, hybrid Ceramic bearings, Carbon flange-reinforcement and Carbon endcaps. The flange geometry has been optimized to increase the lateral stiffness of the wheel. Each material was selected to achieve the lowest weight possible. Only available in the lightest colour: Silver.
