The Uni Stem may be one of the most iconic Cook Bros. Racing pieces ever. Its history is as influential as it is innovative. The stem body and clamps are cold-forged for maximum stiffness-to-weight ratio and durability. The stem comes in a 53 mm extension and fits 1 1/8” steerer tubes and 31.8ø clamp handlebars. Adapters to fit 22.2ø bars are available. Classic design, modern technology, the legacy lives on! Like the classic Cook Bros. Racing slant stems, the Uni Stem have a silver body with red, blue, gold or black anodized clamps.
