I have just not been able to decide between these two bikes. I am gonna be doing a 7 day racing event in India and don't really know which one is more durable and why? This racing event will have about 5 to 6 dirt sections of 30 to 50 kms and then transport( non-competitive section - usually 100 kms at a time - at least 3 a day). The terrain is going to be right from river bed to rocky mountain, to desert to slushy and will have a mix of all of them. Please advise why and which bike to get?
