Shimano Deore M590 Front Hub
The Shimano Deore M590 Front Hub gives you the chance to enjoy some extra-smooth action for a long time. The cone race surfaces are treated with Cubic Boron Nitride to ensure low-friction and a long bearing life. The front hub has single contact seals that do all the hard work for you by keeping the mud and water away from the parts. As an added bonus, the Internal grease sleeve helps maintain and increase the service life of the hub by holding the grease in the bearing housing.
