Rush owners: any of you have ride time on a superlight or flux? I read the thread on SLight v Rush and some good feedback there. Just looking for final thoughts as I prepare to make the plunge. Intended riding for this bike will be endurance events and a few trad. XC races. I'm a light 5'6"rider. For comparison I did not like the ride of the Blur (rode 'heavy' and too much bob during climbing).
