[QUOTE 2147530, member: 45"]Too much risk of ripped bar tape, scratched levers and damaged saddle[/quote]
Actually looking at my bikes, the highest point at the handlebar end is the tops of the lever hoods and, at the other end, it's the rear of the saddle. The only danger to tape and levers is if you knock the bike over. and then it would be a side impact. I wouldn't think knocking the bike over is any more likely than if you knocked it when it was perched somewhere upright. And it hasn't happened to me, there's a pretty stable triangle that the bike is resting on.
Though, I admit, one bike has nasty plastic tops on the lever hoods that ''tell'' me which gear I'm in, and they're pretty scratched. However, I don't think I've ever looked at the indicator to see what gear I'm in so I really don't care.
