Schal ESP X4 (8/9-Gang | Langer Käfig | 1:1)

SRAM x4 broke within 4 weeks of buying bicycle while riding a trail (Mushrif Park Bicycle Track). The spring inside it broke and was not holding chain tension. Someone told me I must have hit a rock, but I'm sure not. I could be spring failure. Finding this offline was impossible on Dubai strangely. Tried calling all the major brands, visited many cycle shots in Satwa, finally ordered this. After replacing with this, its working as it supposed to be, only completed maybe 50 kms so far on this new set. I hope it lasts. If not, might have to change the groupset. Build quality and print on it looks same as the original. The product did not come in SRAM packaging, so no comments if it is indeed original or copy, but built quality looks pretty solid comparatively.

Para bicicletas de 8 velocidades es un cambio robusto y fácil de instalar que funciona perfectamente y no se desajusta fácilmente.

La qualité est très bonne. De plus, on peut démonter les galets pour installer le dérailleur sans changer la chaîne. Et concernant les réglages : très faciles et précis. Mais attention : c'est un dérailleur SRAM donc pour manettes SRAM en rapport 1:1 donc si vous avez une manette shimano, ça n'ira pas avec !

El producto es básico pero en realidad es de muy buena calidad bastante recomendable

Montato su una MTB Rockrider 520 al posto dello scadentissimo e plasticoso X3. Questo X4, perfettamente compatibile, appare più robusto, non fosse altro perchè non è tutto di plastica. Per quello che costa fa il suo dovere. Poi per meno di 20 euro non si può chiedere la luna.

my X3 version broke which is hardly surprising, it was plastic and cheap. this, the X4 has far more alloy parts in it, the jokey wheels are replaceble and the bearings are much smoother. Changing seems smoother. its easy to set up and well worth the few pounds extra. The X4 is a direct replacement for the X3.
