Bought a Vitus Energie from Wiggle in July, it has Sram Rival, never rode it much til recently, the shifting was never perfect but I fiddled a bit and got it going OK. Took it to my LBS today and they tell me the hanger and mech are bent, £160 to replace both and stick a new cable in. I’ve emailed Wiggles warranty dept and explained the situation, what are my chances of them standing over this?
