Used for 1 week or less
For me I could not get this to work, I have 22,32,42 crank set (btwin), but no matter how I adjusted it the throw just did not seen adquate to move across all 3 rings.

I have a brand new chain, new rear mech, and the crankset and rear cassette are only 1 year old.

I returned to my 13 year old suntour one and that works well (in fact the stoke is a little too far on that)

Response of the brand
Thank you for sharing your experience of using this front mech. Installing a front derailleur can feel like alchemy sometimes and certainly isn't the easiest to install, especially with a triple chainset.  MBR probably has the best film available on this topic: https://www.youtube.com/watch?v=AY7DR6efyEY
If after checking all of these points, there is no joy, please feel free to return it to us for an exchange or a refund.
