Great info on how your pedals fared and the relative environmental impact is interesting (isnt ti quite abundant but tricky to refine? )

It is wonderful though, and I’ve chased useful lightening with: stems, quill bolts, bbs, seatposts, bolts and even axles. But all of those add up to about the same as a couple of days fasting or a big piss before your ride.
Weight saving off ‘the engine’ becomes much more critical with advancing years and slowing metabolisms!
