DO NOT ORDER FROM THIS PLACE!!! Save yourself some headache and keep yourself from losing your money! NO SERVICE WHATSOEVER! Ordered 2 weeks ago, and they sent me the wrong product. When I contact them, they claim they Don t refer to that type on their website, even after I proved with links and screenshots of their website!!! When I ask how to get the right prodimuct and where to I have to return the product, just the few words as answer from them: "we don't refer to that specific, you type, you are wrong! (?????!!!!!!) I post underneath the photos with the delivered item, the ordered item and the screenshot of their website incl their description as proof. They claim they don't refer to Shimano HG 12 speed, 9100, 8100, 7100. Convince yourselves! NEVER ORDER HERE AGAIN!!! DON'T MAKE THE SAME MISTAKE!!
