"The bike is called the Honda RN01 and is the team bikes for honda g-cross team, who is greg minnaar, matti lehikoinen and recently brendan fairclouth. Basically that gearbox is a derailleur and a cassette in a box (interesting fact: most gearboxes (or for jargon: internal gear transmission system) are made by sr suntour), although honda keeps everything, from the geometry to weight to the components to the gearbox EXTREMELY secret. The coolest thing about that gearbox is that you can shift gears while freewheeling, so you can give gas out of a turn immediately. In a interview with Mike van Zyl (Mike is Greg Minnaar's mechanic), he says that only the showa carbon fork setup is worth $20 000 and only the CASING of the gearbox is worth $30 000, so that bike should reach far over the $50 000."
