I don't think it can get any better than this Chris King / Enve / CX-Ray combination. One of the stiffest, strongest wheelsets money can buy with a weight of just 1584g per pair and able to take a lot of hammer.
The unrivalled stiffness of the Enve rims means that lightweight bladed Sapim CX-Ray spokes can be used for a weight and aerodynamic advantage with no concerns over wheel stiffness.
The Enve rims are fully tubeless compatible using either the Enve kit, or just standard NoTubes yellow tape and valve.
The hubs don't really need any introducing but in case you didn't know... 72 engagement points for near-instant pickup from freewheeling, bright colours, bearings that last forever and a nice freewheel buzz make these the best.
