It is the premium deep-section option in this selection for a triathlon or time-trial build where the course, conditions and rider all support that choice.\u003c\/p\u003e\n\u003cdiv style=\"padding:16px 18px;background:#f4f7f4;border-left:3px solid #0F502C;margin:20px 0;\"\u003e\n\u003cp\u003e\u003cstrong\u003eWhat you are buying:\u003c\/strong\u003e A complete front-and-rear wheelset.

A premium race build brings position, tires, gearing and wheels together around the event ahead. The 858 NSW adds Zipp's deepest Sawtooth road-racing profile and current premium hubs to that picture.
