PRO spec hubs that pursue rotational performance and light weight
PHIL WOOD track hubs are trusted by riders around the world, from professional track athletes to hard working messengers. Made of the highest quality American 6061 aluminum alloy, the hub shells boast the highest rigidity and durability.
PHIL WOOD believes that "of all bicycle parts, the hub is the most heavily loaded and continuously rotating part, so it needs the utmost peace of mind" and produces hubs that are maintenance free and durable enough to keep turning cleanly and without breaking.
Among the hubs produced based on this concept, the "Pro " is a product that particularly pursues rotational performance and light weight. The hub shell has been stripped down, and the titanium bolts and aluminum lock rings have been replaced with new ones, and other parts have been updated to be worthy of the "Pro" name.

This product is for the rear, so the front version is available here.
The rear FIXED version comes with a lock ring.
