Really? Rim is 314g, hub is 136g, bolts are 21g, spokes are 148g, nipples are 10g, rotor is 88g, bolts are 14g, tube is 130g, rim tape is 3g and tyre is 418g. Guess if I went with some ti bits and bobs it would be lighter Oh and I've got my rear hub down to 381g now thanks to ti bolts and lighter washers
