about pedals: recently it was said that 'clipless will be lighter than track pedals...' or something. It's always going to be a specific comparison; low-end SPD stuff is often really heavy— for example, both of my MKS sylvan lites with alloy clips are about the weight of one shimano SPD pedal that I had in the house.
Lightest pedal in the world is the Aerolite, second is the Orb 3 by the sadly defunct M2Racer, and then, and then, and then, is track pedals - Campagnolo Super Record, with titanium spindles, hard to beat.
And remember, no need to hyphenate ly adverb compound phrases. Mostly stock.
