The 1.5" Headset Lower Cup Assembly
can be used to adapt Scott Roxter, Trek Roscoe, Avanti Montari and other bikes to take a tapered steerer fork like the Manitou JUnit
On some bikes (like 20 inch Scott Roxter) the frame head-tube is not machined in deep enough to allow fitment of the headset assembly.
Purchase this machining product with the 1.5" Headset Lower Cup Assembly
and we will machine down the headset cup spigot by 5 mm in length.
