SramSchal 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.
