Wyatt Earp Posted June 4, 2012 Posted June 4, 2012 Lighter than my eyelids when I see a thread like this so late in the afternoon. But around 160 grams.
splat Posted June 4, 2012 Posted June 4, 2012 Between 70 & 100g Depending if its road or mountain, PF30, BB30 adaptors and which brand
Wyatt Earp Posted June 4, 2012 Posted June 4, 2012 Between 70 & 100g Depending if its road or mountain, PF30, BB30 adaptors and which brand Yip, just weighed a Pressfit GXP quickly, 45 grams per cup.Must be A-cups.
Bike Mob Posted June 4, 2012 Posted June 4, 2012 pressfit BB will be under 100g. I'd say arou75g -80g on ave.
Speeding Posted June 5, 2012 Author Posted June 5, 2012 why ?I have entry level crank(M552) on my Trek that i want to upgrade to XT but want to know how much weight i will safe as my bike total is 13,3 kg. want to get to about 12,5 kg.
splat Posted June 5, 2012 Posted June 5, 2012 There is not much of a difference in weight between BB'sThe crank itself will be lighter though.

Go for a nice long ride and take many photos and put them on your Bookface webthingy. Take some sarmies along and sit under a tree somewhere and appreciate the location. This continuous hunkering after lightweight BBs and bits is almost as silly as Sandton kugels who can't go out because they don't have the latest Mosquito belt or their lipstick is smudged. Stoppit!

Morning Johan! Do you perhaps know if one would save a considerable amount (in terms of weight) by cutting down the lengt of one's bottle cage Ti bolts. Also, I suspect one can save some weight by drilling a couple of holes in your BB, which can also help to drain water as a side benefit? I know it's a long shot, but I'm also hoping to save some weight by cutting down any excess length from my seatpost and removing the padding from my saddle totally....maybe even remove my grips totally... Is there any truth in the rumor that one can save a couple of grams by making sure your brake hoses are the perfect/shortest length, because you can get away with less mineral oil in the system?

Is there any truth in the rumor that one can save a couple of grams by making sure your brake hoses are the perfect/shortest length, because you can get away with less mineral oil in the system? Dear "The V" You can save some considerable electrons by shaving off "The" and only calling yourself "V" Mineral oil, as you point out, is extremely heavy. The best way to deal with that is to move your rear brake lever to your seatpost and thus minimise the hose length. I mounted my front brake on the fork's right stancion. That saved 6 inches of mineral oil and, it also serves as a lockout, which in turn saved more weight. Drill everything, don't use sealant and go for the new 20" wheel standard that makes the bike more responsive, lighter, faster and of course, stiffer. Not only do you save wheel weight, but your cranks can then come down to 117mm, which as you guessed, saves more weight. Toss the saddle, sitting is for sissies. Grips? Are you crazy. I keep some dried contact glue on my bare palms and grip the bare aluminium quite effectively that way. And did you know that aluminium has half the density (weight) of Titanium. My bottle cages are made of alu. Not strong enough to hold a large bottle but then again, those weigh too much. Keep it up, it is about the bike after all. Edited June 5, 2012 by Johan Bornman

What would you want to do that for, save extra weight by attaching it to the left stanchion ,the caliper does sit on the left hand side. TheV 1
Iron Posted June 5, 2012 Posted June 5, 2012 What would you want to do that for, save extra weight by attaching it to the left stanchion ,the caliper does sit on the left hand side. you all wrong ! i have removed the breaks completly , use my takkie on the back tire to stop , no breaks to service and the bike is way light .
Wyatt Earp Posted June 5, 2012 Posted June 5, 2012 you all wrong ! i have removed the breaks completly , use my takkie on the back tire to stop , no breaks to service and the bike is way light .Ditch the shoes and go fixie.
