Description

What headset will these bearings fit?

Integrated (IS) headtubes have molded integrated races inside the headtube that are a part of your bicycle’s frame. To install the bearings, you just place them into the races integrated into the headtube of the frame.

IS42/28.6 – IS52/40 would work on an integrated headtube (IS) that has an upper headtube with a 41.8mm inside diameter (which we round up to 42mm) and a lower headtube inside diameter of 52mm, and the fork would have a 1 ⅛ ” into a 1.5″ tapered steerer tube.

IS42/28.6 – IS47/33 would work on an integrated headtube with an upper and lower headtube I.D. of 41mm and a fork with a  1 ⅛ ” into a 1 1/4″ tapered steerer tube.
