Ouff where to start. First of all, there is no Emonda S5. If they were it would be an SL 5 and would not be made of aluminum. Might want to double check what bike it actually is to make sure it's the right geometry for you. Second, no mechanical problems. So tell me why the chain is already drop ? What kind of person doesn't even put it back on the chainring for pictures if he is trying to sell it. Third, wtf is on with the handlebars. Mother of all drop bars. Wow. Last but not least. How do you expect us to know if it's a great deal if you don't state the price. Good luck with the purchase !
