CANE CREEK TOP & BOTTOM HEADSET ASSEMBLIES - (FOR TAPERED HEADTUBES / STEERERS)
A "Tapered" headset is generally any headset configuration in which the bottom bearing or assembly is larger than the top bearing or assembly. In a tapered configuration the top and bottom head-tube standards are typically independent and it is critical to identify each. For example, a Cane Creek standard IS 1-1/8" top head-tube assembly may be paired with a 1.5" traditional cupped bottom head-tube assembly.
Conversion parts and assemblies allow straight 1-1/8" forks to be used with tapered head-tubes. Conversion assemblies also allow straight 1.5" head-tubes to be used with tapered or straight 1-1/8" forks. Due to the great number of combinations, many headsets are offered as separate top and bottom assemblies for maximum flexibility.
