The completely new Ultegra 6800 11 speed Tubless/Clincher wheelset. With this wheelset Shimano offers their top technologies for wheel building. Low-friction seals effectively shut out water, mud and dirt without affecting rotational smoothness.
Different rim shapes for front and rear optimized lacing and reduce weight making this wheelset both lightweight and strong. Previously only available in the Dura Ace hubs, the Digital adjustment system eliminates the double lock system found on most cup and cone hubs. Instead a ratcheting ring is hidden under an end cap, and to adjust it you just remove the end cap with a 5mm allen, and then simply rotate the ring to remove any play in the bearing.
