Stronger, lighter, more attractive. The Profile Design Cobra S Stem hits the trifecta. The Cobra S is part of a growing trend -- carbon-wrapped aluminum. They start with a 3-D forged 7050 aluminum stem and wrap carbon-fiber cloth over it and add resin. The result is a great stem that has rigidity of carbon-fiber and the light weight of aluminum, or vice versa.

As with their Aris, Profile offers the Cobra S in sizes you don't see other places. The size run begins at 80mm length and moves up in 10mm increments to 120mm. The stem angle is 84°/96°.

The faceplate is forged 7050 aluminum. All the bolts are made from stainless steel. The stem works with 31.8mm diameter handlebars; the clamp width is 40mm. The rear clamp height is 40mm. It comes in 31.8mm diameter; a reduction shim for those who are still using a bike with a 1" steerer. The Profile Design Cobra S Stem is offered in two colors -- high gloss Carbon and White.
