Bicycle Tapered Headset 1.1/8" to 1.5" for 42mm/52mm Headtube & 39.8mm Crown Seat

A combination of the other styles, tapered headsets will be used with a steerer tube that has a 1.1/8" or 1.5" lower diameter, and a 1.1/8" upper diameter. Headsets for such frames and forks can be any combination of traditional, internal, or integrated headsets. It is very important to accurately measure the inner diameter of the headtube top and bottom to narrow down the headset model needed. In some cases, tapered headtubes can be used with a straight 1.1/8" steerer tube if a reducing headset race is available for that headset.
