Product Description

Zipp doesn't hesitate to extend their craftiness beyond their signature aerodynamic wheels. This SL Speed Carbon Stem is a prime example of Zipp's quest to reshape bike componentry from bottom to top. The most notable aspect of this stem is its ethereal lightness (a mere 102 grams in 100mm length). Being this light, Zipp uses exacting construction standards and some forward thinking to maintain the same top-notch level of performance and durability you'd find on their other go-fast products. The SL Speed Carbon Stem has rearward facing stem bolts, similar to what we've seen on Oval stems in the past. On Zipp's design, the bolts thread directly into a two-piece carbon/titanium faceplate. On the backside, the single-bolt steerer clamp appears standard in every way, but Zipp found, through product testing, that normal fasteners don't always seat properly in their bores when the clamp is torqued to spec onto the fork steerer tube. To alleviate this, they added self-aligning washers to ensure positive contact between the stem and the shoulders of the fasteners. This minute detail is one that allowed Zipp to create the main structure of the SL Speed Stem from 100% carbon fiber, without any co-molded alloy parts. The Zipp SL Speed Carbon Stem uses uni-directional carbon fiber, laminated in such a way as to have incredible torsional stiffness to resist twisting when you're really cranking on the bars in a sprint or uphill. It has a 31.8mm clamp diameter and is available in six lengths from 80 to 130mm in 10mm increments. The stack height at the steerer clamp is 40mm and the stem is angled at +/- 6 degrees.

2007 carbon speed SL with broken race.

I pulled the boot to see why the fork was feeling so rough all of a sudden. I found a bearing race hanging down and some small plastic pieces that look like they used to be a ring of some sort.

Lefty Speed Carbon SL with DLR Problems

So I did a 24 hour race and all was well. Midway through the race I lost about 20 psi. and had some clunking at compression and rebound. I knew I was about due for a bearing reset so I thought that was the problem. I stopped in the pits aired up and things felt a bit better with less clunking. Then ... Read More »
