I've heard alot of possitivity about the Short GU in contrast with the long version? From both Gaz Meridith and Danny Foster. After having ago on the short Gu it feels well flickable, the high BB isnt really noticable at all, perhaps because it is 60MM BB rise and the Pythons are 55MM makes that 5MM difference hardly anything. It gaps alot easier than any Mod i've ridden, and sidehops especially well, this is probably due to its short chain stays making it flick up alot easier, in comparison to the python which has a longer back end.
