Hi there - I am buying my other half a surprise first road bike (I have no idea) - I am wanting to buy a second-hand Decathlon Triban 500SE and think I have found one but it was advertised as a 500.. I asked if it was a 500SE and the guy said yes... is there any way of knowing just by looking at the bike if it is a 500 or 500SE?? Just so I dont get the wrong one... Thanks so much in advance
