My evolving [Google Doc meant to cover a range of Rocker Plate Info](https://docs.google.com/document/d/1k34t_WIy4W6oNtsO0vN_uDx3TRHmY49jk7SJ_14u1Ww/edit?usp=sharing).

# What is a Rocker Plate?

- A “Rocker Plate” is a device used to add one or more motion (degree of freedom) to an otherwise rigid bike & trainer combo. Most designs sit on the floor, and then support the bike, trainer and rider on top of them. The rocker plate has mechanisms (simple or complex) that allow motion for the rigid trainer bike and rider combo.

# Why use a Rocker Plate with your Rigid Trainer?

* * *

1. **Comfort In & Out of the Saddle**
  - The small side movement of the saddle, even when seated, helps relieve pressure on the sit bones and soft tissue.
  - The added rocking motion encourages standing because it feels more free than rigid trainers which can lead to more frequent breaks between seated efforts.

- When you have a bike that is perfectly comfortable outside, and then leads to problems when ridden inside, I feel it is important to look at what is different. When you do, there are two key differences.

* * *

1. **Core & Upper Body Use**
  - With softer leveling spring settings, it requires more engagement from the core and upper body to ride level and maintain a smooth pedal stroke.
  - This is true for seated and standing efforts, when compared to rigid trainers.

* * *

1. **More Standing Pedaling Motion Freedom**
  - Standing pedaling on a rigid trainer is awkward and not at all like riding a bike outside.
  - On a Rocker Plate, the bike & trainer are more free to lean to both sides. This can allow the rider to move in ways that are less awkward than on a rigid trainer.

* * *

1. **Frame Stress**
  - Unproven by testing and data, but Rocker Plates are likely to reduce stress on frame members since they allow float and likely reduced side-loading to the frame members.
