Your smart trainer
The trainer determines the exact ULTRA geometry and contact points.
ROCKERON MOTION SYSTEM
Go longer indoors.
ROCKERON ULTRA adds controlled, trainer-specific movement for a less locked-in ride—built for daily training and ultra distance.
BEFORE YOU BUY
Clear answers.
ROCKERON is deliberately trainer-specific. The Setup Finder is the safest starting point.
Is ROCKERON universal?
No. ROCKERON products are designed around named trainer housings and contact points. Choose the exact trainer and bicycle type in the Setup Finder.
What changes between Balanced and Performance?
The ROCKERON hardware stays the same. Performance includes a larger four-stiffness Motion Ball library and unlocks every published Ride Feel.
Do I need to change Motion Balls before every ride?
No. Start with the supplied recommendation and keep it until you want a different ride feel. The profiles are optional guidance, not homework.
What is the Pain Cave for?
Search a supported route and copy its tested Motion Ball starting setup. The route guide is the useful destination; the ride profiles only explain the general character.
HOW IT WORKS
One compact system. Four clear parts.
Trainer fit, ULTRA hardware, Motion Balls and Ride Feels work as one repeatable system.
Trainer-specific ULTRA
Rear modules and the matching front support create controlled lateral movement.
Motion Balls
Four stiffness levels change softness, support and progression without tools.
Ride Environments & Ride Feels
Guided Motion Ball layouts turn the ride feel you want into a repeatable setup.
THE RIDE
Controlled motion. Built for endurance.
ROCKERON ULTRA lets the trainer follow each pedal stroke instead of holding the bike rigidly in place. The result is a more natural ride feel designed to stay comfortable when the session gets longer.
- ✓ Controlled side-to-side movement
- ✓ Ride feel changes in seconds
- ✓ Compact enough to stay installed
MODULAR BY DESIGN
