Shimano Yumeya
The parts consist of rear derailleur plate -7g, tension and guide pulley set -1g, cable fixing bolt and pulley bolt for rear derailleur -2.8g, cassette sprockets -15g, HG chain -10g, outer casing -10g/m, brake hose, connecting bolt for brake hose -6g, shift lever bracket band, outer adjust plate for shift lever, bolts for shift lever -4.2g, crank arm fixing bolt, lid for disc brake lever -3.5g, bolts for front derailleur -2.4g and brake caliper bolts -9.2g. A lot of the parts are strictly for bling and have no weight savings. Total savings=71.2g to ? (depends on casing length)
The parts have quite a bit of bling factor along with some weight savings. When I spoke with one of the Shimano reps, and he was unsure when the parts would be for sale, how much they will cost and whether parts would be sold individually or only as a kit. He was sure that the chain and the cassette sprockets would be sold separately, and I am sure they will not be cheap.
