Ooops, I misspoke. It was 114 grams:

what was it before?

Soloist Assassin

Installed new seatpost/saddle -109g, +6g of stan's in rear tire, and cut -12g (-9g of bar, -3g of tape) or 1" off of each side of the Vukas. since this pic.

Congrats SA... you finally got to the 12.XX lbs mark huh? wow I forgot how much you wanted to get to that point, and subsequent work you put into getting there.... how's the ride with the new post/seat configuration?

Soloist Assassin

Thanks, it's really better than I could imagine. It feels kinda like my SLR, but I can feel where he made some tweaks to work with his design to make it ride even better. It basically only has support in the middle of the saddle. So there is little to no flex there. The sides however flex nicely, and it makes for a really great ride. However I did hit one big bump while seated, and I could feel it a bit more than I would of liked to. I wish I would of seen that one coming for sure. It wasn't much harsher than a regular saddle, but it was a bit worse. The flex of the rails kinda help there I think. As long as you can make sure you get up out of the saddle for those, it's awesome. It literally feels like the shape was molded just for me. I like the shape better than my SLR, but the flex in the middle helps with those big bumps.

I think mine was 144g with about a mile long post.

^good to hear. it makes your bib/short choices a lot more important now too. there might be a specific/different bib/short that works better with the new seat.

hey guys if you want some weight weenie handlebars (40cm 212grams) with and old school anatomic bend (that puts the brake hoods a little below the flats) I'm selling off my 3T Zepp XL bars on the bikeforums marketplace for $39 shipped.

They're in pristine condition because I switched immediately to Ritchey Ergo Curve handlebars - I love having a straight line from the flats to the hoods.

That is awesome, can you see any other areas to... Diet? You're bike is functionally lighter than most I've ever seen. Yes, the carbon saddle is a bit WW, but even then most everything is not very... fragile. I'm still waiting on my bike clam. Waiting and pacing...

Soloist Assassin

I could definitely put lighter bars, and stem on. Probably could do a lighter fork, i-link cables would save a little. Fibre-Lyte chainrings could save a bit. Most of those things aren't an option for me, except maybe the i-links. I like the bars, and stem stiff, and aero. Here is the whole bike, and a current build list.

Its not uber weight weenie, but I'm happy with this:



Thomson Masterpiece 27.2 240mm setback post.

I'm also happy that the post weighs exactly what Thomson lists. There's nothing more annoying than seeing that you've got something heavier than advertised.

I just got back from a quick test ride with the setback post and it really is more comfortable for my fit. There's a weird paradox of being more stretched out and having less pressure on your hands and also being able to ride the drops easier. The newer compact curve handlebars that have 73-85 reach also affect fit to a large degree.

I wonder if Thomson patented that mid bend setback seatpost design, because the setback and 0º setback posts weigh the same. I figure KCNC could have an under 120g setback post with the same design.

Soloist Assassin

Could could tune those Thomson posts to be lighter you know?

runningDoc

I suspect the main difference between the KCNC/Woodman type of posts compared to the Thomson is just the seat rail clamp mech the actual seatpost tubes must weigh nearly the same. Thomson's is beefy and solid and obviously weighs more. There's probably a way (aftermarket kit perhaps) to put in a lighter seat rail clamp mech.


EDIT: yup I did a little google-fu-ing and saw there are numerous aftermarket carbon cradles and Ti bolts for Thomson seatposts. Theoretical weight savings is about 34 grams.

The Ti bolt set are cheap (you can get them for under $15 shipped compared to the 20g steel bolts its about $2/gram savings.



The carbon cradles are expensive though (almost $100 for both upper and lower - yup they sell them separately) from a seller in Europe. Seems like a lot of money to save 34grams.

lookin good SA lookin good

I pretty much only use high end Castelli bibs anyway.

Thanks DDF.

To the OP and all the other weight weenies posting on here: Lots of good info on this thread. So far I'm thru the first 14 pages and realize that I have a LOT to learn (total newbie here). One thing I'm curious about that I haven't seen posted yet are your bike sizes. That's got to make some difference doesn't it? I ask because I recently purchased a Giant Defy Advanced (XL) and its a porker at 22lbs and change. What would be a realistic weight that I could get this bike down too? Also, I know an endurance bike and race bike have different geometries, but are the endurance bikes heavier by nature as well?

ritchey WCS Carbon Evolution bars 40cm. the weight is great. maybe I'll save these for a new weight weenie carbon frame build for this winter.

The ritchey classic curve bars I have on the bridgestone are pretty, have the great compact modern brifter-friendly curve, but weigh in at near 300grams for only a 40cm bar.



The pleasant surprise for me is the Ritchey Classic Stem. the 100mm comes in at 111g. you can find them for under $70. If you ever need a light weight polished silver stem with a 31.8 handlebar clamp diameter its a great option.




does anyone here have experience with the aftermarket titanium stem bolt kits for ritchey stems?

ravenmore

I might be buying this stem soon. I really want to go to Vuka Sprint bars and would need a silver 31.8 stem.

runningDoc

the only problem for the ritchey stem is aesthetic - in my opinion - is that its marketed toward classic styling and builds (like my build), but the stem is very thick in diameter - a lot wider than all the tubes on my steel frame (28.6).

if you're putting it on a carbon/Ti/Alu frame which has thick tubes already then its great, but it does look bulky on an old school steel build:



i guess it must be really thin Alu which has to be a thick diameter tube for stiffness and weight savings.

ravenmore

btw - toying around with the idea of getting a silver kcnc post too.

ravenmore

It would be going on my S-Works, so it would probably blend a little better for me.

X-LinkedRider

You are going to lose a lb or two just by switching out to lighter wheels. And there is room for weight loss in the components and tires and everything but the frame really. (Unless you have too much time, a dremel, know a frame painter, and hang around SA too much).
My guess is you could get it down to be around 17lbs without having to drops thousands!
