Andreas F.wrote a review of Kinetic Riser Ring on January 22, 2019
Familiarity: I've used it several times
I didn't think differences in riser blocks really mattered. Each one seemed just like every other one. There is something about the dual contact points of this one, though, that allow my front end to move a tiny bit - both flex down a bit and move side to side. I hate when riser blocks force your front end to stick in one place. I want at at least a tiny bit of movement and this one make indoor riding a tiny bit better.
