I just can't see the sense in taking an expensive bike, then making it more vulnerable to damage, and adding extra weight. The functionality of both bikes is now on par with your bike, so why waste all that extra money in the first place.
yet you put DH tyres on it and there 1435g each lol when my rear is 1065g and i only use it because the side wall are thicker and cant rip it off the rim going round corners to fast with 20psi in it.
same with the bag as it holds the batt i have and 2 usb cables for the phone light and camera as without it both will last an hr at best now its 6hrs plus+ and dont get stones flicked in my face
at 20.9kg my bike is one of the lightest anyway but its still a fkn tank and thats what i call it.
