I bid on some aero bars the other day on ebay, didnt really expect to win but i bid about £60 for some nice Stryke Carbon ones. Would you believe it however, a few hours after i put the bid on, a friend of mine called me to tell me he managed to wrangle some free aero bars off a friend who has some on a bike he never uses now, having bought another new TT bike, and he would give them to me. I spent a day continually checking ebay hoping somebody would outbid me, but alas, they didnt and I won. I definitely don't want the ones I have bid on now that I have some fairly good ones for free, and £60 could go a long way for me at the moment. But equally, I dont want to be an absolute **** to the person I have bought them off on ebay and not pay up. What do you think I should do?
