The DT Swiss EX471 are built to be bullet proof, with multiple pro riders using them for DH World Cup racing. We give you the choice to go with a Pure build featuring Pure D400 hubs, or go all out with DT 350 hubs. The D400 features 24 points of engagement with a 3 pawl free hub. The DT Swiss 350 hub has 18 points of engagement, but utilizes their Star-Ratchet design for uncompromising strength. These wheels are built with DT Swiss Competition Double Butted 2.0/1.8/2.0 spokes in a 32 hole configuration front and rear.
