Continuing the momentum generated from the classic, the new U.P. was designed to be lighter than the original. Still the Jack of All Trades we all fell in love with, the new U.P. can be ridden with 700c or 650b/27.5" wheels, with slick road tires or knobby trail tires, and with drop handlebars or flat MTB bars.
2013 Zipp SL Speed Stem<p>
Fashioned from a mere 102 grams (100mm length) of carbon and titanium, the SLSpeed proves that a superlight stem doesn’t have to compromise on stiffness, strength, or reliability.</p>
To make the most of every gram, the SLSpeed’s unidirectional carbon body contains no embedded metal. Rearward-facing bolts thread directly into the faceplate to minimize weight, while the bottom edge of the clamp is design to contact the body of the stem in order to reduce flexing. A self-aligning washers at the steerer clamp mean that the bolt stays straight as it’s tightened, reducing long-term stress on the system.</p>
Available in 80-130mm lengths. ±6° angle. 31.8mm clamp diameter.</p>
