Prime RD020 disc brake rear road hub features a superlight forged alloy 7075 hub body that has been CNC machined to reduce weight without compromising structural integrity. The RD020 features 4 pawls and 26-point engagement, which ensures superfast, pick up for increased acceleration and positive engagement.
Our hubs run on premium Japanese sealed cartridge bearings for ultra low friction and superior bearing life comprising of two in the hub body and two in the freehub body.
The freehub body has a superlight alloy construction and features our ABG (Anti Bite Guard) technology where an integrated reinforced steel rib has been incorporated to eliminate damage from driving forces placed on individual sprockets.
A grease port has also been added for home maintenance to further prolong bearing life and reduce service intervals.
