In addition to Mike’s point.
1) Could well do considering the Aberdeen FC mascot is Angus the Bull!
2) I do agree if the bull isn’t to be on the back something recognisable needs to be. Especially when racing or doing events you only really see the back of peoples tops. You only see the front when your standing (podium, before race, etc) but most photos see you hunched over on the bike (so can barely see fron) or from behind.
Again this doesn’t help with the original question either! 😀
