Hi! I dont know where to start. I've been eyeing on IBIS Mojo HD but I dont afford to build the whole bike substantially lighter than my current DH bike (IH Sunday with 888/Avy & 823EX/Hadley) . If I could find a way to get sub13kg for allround FS, it'd be cool but probably it'd be a used frame within my budget. I got sneaky idea, how about Sunday frame with lighter parts when it is not for dh use. I usually take apart Sunday for traveling to a place to ride (I dont live close mountains and have to take train or buss) So 55CR, light wheels as EX721 with Hope or SuperStar hubs, single ply tires would work? Im not expert on geometry but what HA I get on 170 or 150mm front? my uses are wide ranging from urban to light forest, sometimes to go up and ride on flat. I have older frame with ancient Specialized FSR that would be imposible to use any else than gravity. your thoughts?
