Without a high(-ish) pivot I think anything getting close to 420 mm with a 29er rear wheel is a major achievement (or front triangle massaging) situation. Regarding riding style, I'd say Moir knows how to handle a bike. EWS champ? Meh... Irrelevant. In all seriousness, talking about hanging off the rear, any time someone mentions that I instantly remember Chris Kovarik (in person from Maribor to be honest) who looked like he was surfing off the rear of the bike. True, different times, different bikes, but yeah. Crazy Australians :D
