a dyno is a dynamic climbing movement. Typically a dyno has all points of contact come off the wall for a brief period of time. While its not a requirement to lose all points of contact to be considered a dyno, momentum must be used to complete the movement at the very least.

On this site we would like to see all types of dynos, although we would like to limit the database to problems where the crux is the dyno. So longer problems with a jump that isn’t the crux of the problem should be omitted.

To submit a dyno to the site please create an account and then fill out the form here. Your submission will be held for review until you are a trusted user.

This website is intended to be a place to consolidate all dynos in the world to one place. This makes it easy for dyno lovers to search for new dynos to try in any area they visit. It also has critical beta about hold type, movement, and warnings about aggressive rock texture that most guides ignore.

Here’s the thing, all grades are very subjective. Dynos are even more subjective. I can tell you that most of these dynos are pretty hard and require a balance of skill and power. Some are exceptionally morpho. I believe that traditional boulders are given grades based on Rate of Perceived Exertion (RPE), whether it is subconscious or not. Since most dynos are done in less than a second, that RPE can feel a lot different than a 15-mover roof boulder. One thing I can say for certain is relative to each other most dynos seem to scale with difficulty proportionally with V grade. Your mileage may vary, but if you are doing dynos for points you are doing them for the wrong reason.
