### ⭐⭐⭐⭐ Arrived promptly and in perfect condition. Good price.
*by M***E on 12 July 2021*

I bought it to allow maintenance of chain tension on a hub geared bike without moving the hub in the dropouts. Seems to work pretty well. It is not ideal for this function because the lateral adjustment is at it’s absolute inmost limit. I think it’s designed to allow a multi sprocketed bike to be used as single speed. For my purposes it would be better if the main arm slanted inwards to naturally align the tensioning jockey wheel with the sprocket of the gear. Despite this I am very happy to use it on my bike and won’t change it unless I discover a better alternative.
