I bought the EC-90SLX and RETURNED THEM after finding no OEM instructions, compression cap/sleeve and original box...plus, it was heavier than stated(330g uncut).
I have to admit- the imposter was very close to the real deal. But Easton includes EVERYTHING(OEM instructions, proprietary compression sleeve/cap and even recessed front brake bolt) with their product.
Having no such thing as copyright laws in China and their uncanny ability to visually reproduce virtually everything has made them notorious for being all IMITATION....and no INNOVATION(no SLUR intended!!!).
