12\15, recomendation depends on usage
36T version was bought and tested.
Rode over 8000km by the light rider.
No problems observed.
Personally, we will buy the original DT ratchet, but this lot can save you 30$.
Rating decreased, as other rider reported few incidents with misengagement on heavy load. Ratchat did not fail, rider did not fall.
This item will work fine for “normal” usage, but for racing kind of usage (short powerful sprints) we would not recommend it.
