i should have my ilink / mini ilink / powercordz setup in less than a month, and the new Red stock cables as well. I could weight everything and give you details on actual weight savings you should expect, if you don´t mind waiting.
note 1) if after seeing the actual savings figures you dont want to change cables, I'd suggest Berk combo, might save something close to the 160 gr you need. can't wait for mine, but he needs to find a toupe he can borrow in order to copy the shape for my combo.. I think price/grams saved would be much better than swapping the cables, and there are plenty good reviews of his combos around..
note 2) I still find your total weight faboulous! my build when finished will be very close to 12 lbs and it is so similar to yours.. I still think I can explain maybe 1/2 a pound difference, not a full pound though. hopefully I made some wrong calculations and might turn out a bit less than 12 in the end..
note 3) in all, Im much likely not using the powercordz on my build. reason? Im aware powercordz dont go well with mini I links, Ive seen people here stating they use this combo, but no one replied me about installation/performance. there is some deburring issues in place, Pcordz aknowledge this in this forum and to me by mail. i THINK Ive seen people using Pcordz with ilinks (not mini) both for brakes and shifters. however, I believe the weight savings are lesser than "regular" gables in the minis. finally, why not use regular cable + Pcordz where I can? Id have a bike with one silver cable and one yellow cable, the only colour I could get the cordz in time to ship to Brazil. that would be just too much to take lol... I could get away with both yellow cables, but this... hopefully Im making sense!
Yeah I don't think there is enough cable on the bike to make a differance, I could be wrong. Nanogram pedals are next, I can justify them as I need pedals for my training bike im slowly putting together, I will through the SP Ti's on it. My brakes are at 228 grams a pair, there could be an easy 50gr saved, my seat at 148g, but what else will work that is lighter(post is at 105g cut now).
