Like their predecessor, the WH-6800 wheelset is both tubeless and clincher compatible so the wheelset is ideal for the rider wanting to try tubeless tires, but can use standard clincher tires with tubes as well.. Tubeless tires offers great ride quality due to the lack of friction between tube and tire, simply because there is no tube. Also, you cannot pinch a tube if you do not have one, so flat frequency is sharply decreased. In addition to regular road riding, the WH-6800 can be used with tubeless cyclocross tires allowing lowers inflation pressure to achieve excellent traction.
Straight pull spokes are used with a slightly less-butted spoke on the rear drive side. This lets Shimano custom-tune the ride for comfort over the bumps and solid performance for climbs and sprints. The alloy rim is light and strong as expected while the hubs are easily serviced with standard tools.
The freehub body accepts 8, 9, 10 and 11 speed Shimano or SRAM cassettes. One pair of skewers and UST valves are included. Product summary: great wheel, great value.
The Ultegra WH-6800 wheelset is comaptible with Shimano and SRAM 11 speed cassettes. They are supplied with a thin spacer to make them compatible with 8, 9 and 10 speed cassettes. Also included: front and rear skewers, 2-UST valves and 2-spoke wrenches.
