Product Customer Reviews

ok
Well constructed unit but be aware that due to the actuation mechanism being rather bulky at the rear it will not fit some bikes with limited clearance between the seat tube and rear wheel or mudgaurd.
Easy to install with various mounts for different clamp sizes. Shifting is light and easy
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) Mountain bike Gear selectors shimano ST-EF29-8 / ST-EF29-L
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.

Used this to replace an old derailleur a coup[le of months ago that wouldn't adjust properly and was unreliable. Fitting was easy and it adjusted well. I used this on a bottom pull with a Shimano index shifter and it works well and reliably after it has been set up. I also liked the add on adjustment shims in the clamp which allowed me to make a good fit to the stem. I thoroughly recommend this and would say it is as high a quality as any other front derailleur out there at a bargain price.
I bought the front mech for my old road bike refubishment project (1985 Barry Hoban/Coventry Eagle) and found that the original front mech did not have enough travel to reach the large chainring. This MTB mech has loads of travel and easily helps the chain to swap between the chainrings. It is bulky compared to the Campagnalo mech that it replaced but does the job just as well.
This product does works well. It's actually precise and also shifts gear quickly!
einfach montiert Dank seiner 2 Adapter. und leicht zum einstellen bin sehr zufrieden mit dem Umwerfer
It doesn't take up much space on the frame and works when pulled up or down.
Danke, auch fuer die schnelle Reperatur.
Muy bien, todo correcto
Se regula en pocos minutos
MUY BUENA RELACIÓN CALIDAD PRECIO, MUY FIABLE
cumple perfectamente su función para mi mtb de 3 platos. Se adaptó muy bien al diametro de mis tubos al traer dos medidas diferentes de anillos de goma.
soy cliente desde hace tiempo y siempre he tenido buenas experiencias con Uds.
