Colnago SR9 Stem

Colnago SR9 Alloy Disc Stem The Colnago SR9 Stem is a lightweight and stiff road bike stem with a contemporary filleted square appearance. With a keen trick up its sleeve, this premium component features internal routing for your cables, making it perfect for disc brake road bikes such as the Colnago C64 and V3Rs disc models, whereby the cables/hoses are routed through the headset. Not only improving aesthetics, but this setup also cuts drag, too. Please note, this stem does not include the R41 headset bearing cover, which can be purchased separately.
