Terrible company ordered a new crankset they sent the wrong one a cheaper one I sent it back and am still waiting on a refund they have had my money for a whole month and I still don’t have the part I ordered which is a common part they are readily available or my refund I feel sorry for a school boy who has saved up their pocketmoney to fix their bike and ends up with this service absolutely shocking avoid avoid avoid Go to a local bike shop instead I found them to have a much better service and it cost me less I should have went there first I was up and running again in twenty mins at my local shop will never use Tredz again Also I believe if I hadn’t of been checking my bank statements and noticed they had not payed the money back I don’t think they would ever have refunded my money a whole month they have had my money unreal terrible customer service!!!
