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.
