Race weight.

With the Zipp SL Speed B1 Carbon Stem, it just got easier to get to race weight. Weighing in at just 123g for the 100mm length this featherweight stem is a stiff, secure platform that's light enough to fly up the steepest climbs, yet strong enough for gravel or 'cross. Turning to their partner, SRAM, Zipp used their Exogram™ technology used in the RED cranks to design a stem that completes any race machine.

The Zipp SL Speed B1 Carbon Stem is available in 6 different lengths ranging from 70 - 120mm with ±6º, providing a stem to meet any racer's fit needs. Includes T25 Torx wrench.
