Product ID
Zipp’s SL Speed stem represents the essence of carbon componentry. It’s stiff, secure and light weight with a sleek design that compliments any bike. It’s a perfect addition to a mountain climber’s favourite feather-light road bike, but it’s tough enough to tackle gravel and cyclocross. Designed using SRAM Exogram™ technology, found in SRAM RED cranks, the new SL Speed Stem weighs just 123g (100mm) while exceeding Zipp's stiffness-to-weight standards. Zipp set a new standard of performance and style in 2013 with the introduction of the sprinter’s favourite carbon SL Sprint stem. Now the SL Speed stem broadens their carbon offerings with a light weight ±6° carbon stem. Includes stiff aluminium faceplate and titanium hardware Torx® T25 heads for precise torque readings and ease of adjustment. Zipp chose Torx®-head bolts for its stems and aero bars as they won’t easily strip, provide more accurate torque readers and are durable. It comes down to the way the tool head interacts with the bolt. Common hex tools tend to strip the bolt head if the bolt is over torqued. This is especially true with lightweight bolts. Zipp wanted to be able to use a lightweight bolt with reliable performance. Bolts on stems and aero bars are critical to safety – having a reliable bolt is crucial. The Torx® head is more robust than hex-head bolts and will not easily strip. Torx® fasteners also were designed for use with a torque-limiting wrench (torque wrench), which is needed to achieve the precise torque reading for proper installation. Zipp chose a bolt size, M5, which was best suited for their stems and aero bars. For your convenience, Zipp includes a T25 wrench is included. Also includes a stiff aluminium faceplate and titanium hardware Torx® T25 heads for precise torque readings and ease of adjustment.
