ENVE's Carbon Road Hub blends a one-of-a-kind full carbon hub shell with a proprietary freehub to eliminate bearing play and maximise stiffness, drive response and reliability – making it the highest-performance road hub in the world.

The original ENVE Carbon Road Hub won a Eurobike Design and Innovation award and this second generation improves upon its predecessor in every department while weighing in at just 70g front and 185g rear.

Made entirely in ENVE's Ogden, Utah, headquarters from moulded uni-directional carbon fibre, the hub shell geometry has been optimised to enhance the performance of the brand's SES aero wheelsets – or any other rim you'd care to use.

Flange spacing and diameter have been increased to improve lateral stiffness by 16%. The paired, moulded – rather than drilled – spoke holes in the hub flange reduce weight and allow improved bracing angles that improve drive stiffness, efficiency and ride feel, inspiring confidence when accelerating or cornering.

The hub's axles have also been completely redesigned to utilise ENVE's pioneering Perfect Preload system. By positioning a calibrated wave washer between the bearing and a snap ring installed on the axle, bearing pre-load is consistently optimised. This eliminates bearing play and the need to adjust pre-load yourself, reducing premature wear.

Also increasing reliability are the custom, premium stainless steel bearings and races. These long-life components are enhanced by full-contact bearing seals on outboard bearing faces and non-contact seals on internal faces to improve rolling efficiency. All this means the hubs roll with utter smoothness from day one and maintain their performance for thousands of miles without the need for servicing, making the ENVE Carbon Road Hub virtually maintenance free.

The proprietary freehub body is machined from strong 7075 alloy and anodised to reduce cog bite. ENVE has improved on the previous generation's 18-tooth driver with a new mechanism utilising a 40-tooth ratchet design with a single spring that gives exceptional drive response under power. ENVE has also included a rubber gasket that changes the tone of the freehub when freewheeling.

The freehub body can also be swapped from Shimano to Campagnolo or SRAM XD-R versions without the need for tools or re-dishing the wheel.
