Pulley Block Replacement for EccentriDisk

The smallest part with the biggest impact.

When your flywheel starts slipping, dragging, or feeling off — this is usually the culprit.
The pulley block is the heart of your resistance system, transferring every ounce of effort from cord to wheel.

Refresh your system in seconds:

• Plug-and-train: Designed for a perfect snap-in fit with all EccentriDisk Flywheel Trainers.

• Ultra-low friction glide: Ensures clean, silent transitions through the full eccentric-concentric motion.

Why upgrade / replace?

If you’ve:

• Noticed slack or hesitation during pull

• Heard friction or squeaking

• Been training heavy for 6+ months

…it’s time to replace your pulley block.
