The Zipp SL Speed Stem sets the standard for performance and style thanks to its unidirectional carbon fibre construction. Created using the same Exogram™ technology that is used in SRAM Red cranksets, weight is reduced to a featherweight 123g for the 100mm version. Despite this low weight, the SL Speed stem still exceeds Zipp's best in class stiffness-to-weight standards. It would be the perfect addition to any hill climbing enthusiasts Road bike and it's also durable enough to take on Gravel and Cyclocross riding too.
