Service Course SL

Brand: Zipp

The Service Course SL is the top-end alloy stem in Zipp's Service Course SL road component range. It is 3D-forged from 7075-series aluminium and uses titanium bolts with Torx T25 heads, which Zipp adopted for more accurate torque readings and better resistance to rounding out. Zipp claimed 120 g in the 100 mm length and offered lengths from 70 to 140 mm in the +/-6 degree angle and from 70 to 130 mm in the +/-17 degree angle, for 1 1/8 inch steerers and 31.8 mm bars. It was sold in gloss black with white logos and in a laser-etched Beyond Black finish.
