As long as you are also using Sram 1:1 actuation ratio (ie non Shimano compatible) gear shifters this rear mech is excellent. The shifting is very clean and precise and stays correctly adjusted for a long time. Highly recommended. The only slight flaw is it requires a unique top jockey wheel when they eventually wear out which has 2 mounting holes offset rather than a central bolt so they are not a common part. Other than that brilliant.
I believe that there is a design flaw with this item. When the cable is attached, on the low ratios, the cable actually rubs the aluminium body, which adds to the gear change issues, particularly on the lower cogs no problem when on small cogs. The only solution is to carefully grind the affected area with a dremel or similar (if anyone is interested, I can supply photographic evidence of the fault) also, no barrel adjuster included
I have checked their website and have found some documentation which may help you with your set up: https://sram-cdn-pull-zone-gsdesign.netdna-ssl.com/cdn/farfuture/b53cP8DTiGCIRYRrClAP7qWSnlvu_fcM8-V...
There is also an excellent "community" page on the SRAM website which may also offer additional support as well as a great place to post your photos for added feedback.
There is no barrel adjuster on many SRAM MTB rear derailleurs. This adjustment is done at the shifter. This is how they are designed.
Many thanks,

Mohu jen doporučit pro samoopráváře, mohu jen doporučit
Ahoj, no co mám říci, po mechanické stránce je měnič v pořádku, ale stránka kompatibility? to ne, nesedí na řazení SRAM MRX21 gripshift používané na kolek Rockrider 340 a možný vyšší třída. Převodový index je stejný, pohyblivost dobrá, ale bohužel kompatibilní JEN s páčkami řazení SRAM X 4
Bordsteinkante runter gefahren und sofort Schaltauge abgebrochen...beim genaueren betrachten musste ich feststellen das einige Stellen an der Schaltung auch durchgebrochen sind, sodass ich alles tauschen konnte.
Ware wie beschrieben . Schnelle Montage möglich , wenn man schrauben kann . Leichte Einstellung .Günstiger Preis . Ich hoffe sie hält langer als die Letzte !
Ich verwende das Schaltwerk an einem alten "Vintage" Rennrad (ohne Raster-Schalthebel), also nicht mit den Original SRam Hebeln, daher vermisse ich die Feineintell-Schraube. Ansonsten bin ich mit dem Schaltwerk sehr zufrieden.
Perfecto para mi bicicleta.
Buena calidad precio para recambio de bicicleta de trote.
Perfecto
A un mes desde que me lo han puesto y sin ningún problema, realizando perfectamente el cambio de velocidades.
Me asesoró vuestro encargado de bicicletas, fue compatible porque el mando y el cambio eran de la misma marca. Inicialmente me llevé otro de otra marca y no era compatible. Saltaban de dos en dos. Vuestro encargado amablemente me lo sustituyó y mejoró.

Hola Sandra,
Agradecerte el tiempo que has dedicado en depositar tu valoración sobre el producto.
En cuanto al cambio trasero Sram X4, no se si el fallo con el producto puede deberse a que no han llegado a ajustar bien el desviador o tiene algún defecto la pieza. En ese caso le aconsejo aproximarse a su tienda Decathlon más cercana para que nuestro equipo de servicio post venta pueda valorarlo.
Dispone de un plazo de 30 días para realizar cambios y devoluciones en artículos de marca externa.
Reciba un cordial saludo, que tengas un buen día.
Atentamente,
Javier - Experto producto ciclismo Decathlon Fuencarral
