@topsey and chris, how hard are you going to be riding? I think it would be better to redistribute some weight around to where he needs it from where he doesnt. What i would do is instead of unnecessary 24mm cranks, i would get some thunderbolts or eclat cranks, i really dont think he needs 24mm cranks and even if he did, this bike seems much more tech oriented. I also find installing 2pc cranks muuch easier than 3pc. I think the full guard sprocket may be overkill, with the shadow chain because i have an interlock v2 and im learning crooks and tooth hangers right now, and it is holding up just fine. Folding tires sketch me out personally, but to each his own, and i would definitely get some heavy duty tubes because when riding street and accidentally riding through glass or something, having thick tubes and thick tires really gives you peace of mind, plus never getting flats rocks. Thats just my opinion, and i am in no way bashing your decisions, actually i am incredibly jealous
