Syncros Headset

No, this headset is specifically engineered for select carbon frames, primarily the Scott Scale and Spark models from 2017. It is not a universal part, so please verify your frame's specific headset standard before purchasing.

These numbers refer to the industry-standard dimensions for integrated headsets. The IS42/28.6 indicates the upper bearing size and steerer tube diameter, while the IS52/40 refers to the lower bearing size and crown race seat diameter, ensuring a precise fit for tapered 1 1/8-inch to 1.5-inch steerer tubes.

No, this is a drop-in integrated headset. Because the bearings sit directly into the bearing seats molded into the carbon frame, you do not need a headset press for installation.

Sealed Angular Contact Bearings (ACB) are designed to handle the specific angled loads of steering forces more effectively than standard bearings. The seals also provide a critical barrier against dirt, grit, and moisture, which significantly extends the lifespan of the headset in mountain biking conditions.

The L-shape profile is designed to sit flush against the frame, creating a seamless transition between the headset and the headtube. Beyond the clean aesthetic, it helps shield the upper bearing from debris.
