Useful component but needed a bit of adjusting to get right chainline
Solid component that works well in tensioning the chain of a single speed (freewheel) bike. Using a flip-flop wheel in a traditional roadbike however doesn't leave much margin for error and careful adjustment is required as there is a limit on the outward position of the small sprocket arm. Equally adjusting in the other direction can clause the arm to snag the wheel spokes. All that said, if you take care and spend time on adjusting you can probably run a snag-free, straight chain line.

Arrived promptly and in perfect condition. Good price.
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.

Simple solution for single speed conversion
This has been great - sturdy and easy to adjust (after I took off the needless chain guide on the jockey wheel). Some may not like the noise of the jockey.
