In trials sports, there are:
- Ahead (EC) headsets with external bearing cups
- Semi-integrated (internal bearing cups)
- Fully integrated headsets (bearings sit directly in the head tube without separate bearing cups)
Modern, professional frames and forks have tapered headsets (with a larger 1.5" bearing at the bottom) for stability and stiffness reasons.
Typically, all headsets nowadays have sealed, maintenance-free bearings.
