If you are going to want to shave a few more grams then I suggest...

1) Woodman Death Grip SL Ti Seatpost Clamp. Mine weighed 11.06 g with no issues(Im 165-170lbs). They are inexpensive.

2) 3T seat post? Looks like it will match your frame with the red. Mine also has no issues. I think you are light enough not to break it.

3) Zipp Speed Weaponry Carbon Bottle Cage? Just make sure you get the older ones to match the frame or the new ones that don't show any weave(unless you're not a fashion weenie). After Arundels these are the only carbon ones that really hold your large bottles(from my experience).

Thanks for the suggestion!

A bit of confusion, however... I meant the clamp at the seat, not the seatpost clamp. See, for example, the thread on Thomson tuning. Very tempting. But how hard a whack on the seat will it take to crack the thing?

Revision: I added a Becker saddle (64 g, thus over claimed, but I'm not complaining) to occasionally replace the SL/1, which takes it down to 11.36 lb (5.153 kg).

The Becker/Tune is surprisingly comfortable as long as the road isn't too rough. I thought it would be hillclimb-only, but I've taken it on some long rides and it does very nicely. I still prefer the SLR for rough roads, however.

Hey Dan! Nice job on the bike. I'm currently building up an SL1 as well. Right now I'm hovering around 11lbs. I have a few goodies on the way and those will really help shave grams. My ultimate goal is to get mine to a safe/rideable sub 10lbs and ride it at the triple ironman this October. I haven't cabled mine up yet but, once I do I'll start to post some pictures and stat's. Best of luck with yours!

Thanks! Honestly for a triple ironman I'd bias things more towards the reliability end of the spectrum than low weight. I weenie my bike down to it's low of 11.35 lb only for hillclimbs. For road races, for example, I prefer the more all-around Reynolds MV-32T wheels to my Mt Washingtons, adding around a pound, and for self-supported events, I prefer clinchers which add a lot more weight.

BTW, I set my PR up Old La Honda, a local climb, on Tue with this bike: 16:49 = VAM 1402. I was quite pleased with this result. Analysis shows with my old 16 lb bike I'd used in 2002 I would have been maybe 4 seconds over the 17:03 I'd gotten in 2002. Breaking 17 finally up OLH finally validated a lot of weenieism: it was a major goal of mine.

Dan, A great looking bike, and overall a really good build of reliable yet light parts. I really like the SL/1 frame and I'm happy yours fits you so well. But then again, you are very knowledgeable when it comes to all aspects of fit, physics, engineering, road experience and just knowing and feeling for what works best for you. I feel that really makes the ride experience so much more enjoyable. I changed saddles about a year ago to a Becker and it fits me very well, I'm really happy with it. Mine weighs 43 grams, after I modified it a little, stock it was 52 grams. Also, congrats on your new PR up Old La Honda. It's always nice to climb with a lighter bike.

Thanks, Donald! Tuning a Tune: that's hard-core

. I agree, though, it's a comfortable saddle. I rode it in the Diamond Valley Road Race this past weekend with no more issue than I typically experience with an SL/R, which is to say I had to stand occasionally but never more than a few seconds at a time. Basically normal.

Changes:

Extralite stem: saves 22 grams versus Performance Forte. I got a deal on one I simply couldn't turn down. There's not a lot of demand these days for 26 mm high-end stems.
A thinner top cap for my head tube. This ended up not being needed when I went from the 7 degree Performance stem to the 8 degree Extralite. But it may be slightly lighter.
Switched from Red cables and Gore Ride-On cables to Alligator iLinks and PowerCordz. Super-thanks to Kevin at Bike Nüt for setting me up. This was a job I wouldn't trust to most shops. Bike Nüt really has an appreciation for this sort of stuff. From estimates of length of housings and cables with weighting the per-length mass of the remaining sections, I figure these saved an impressive 185 grams.
Random Taiwanese bottle cage saved 6.9 grams.
I had to change a tire due to a puncture, and the replacement Veloflex Record was 9.6 grams heavier. Also I added glue. I use plenty of glue.

Total mass = 11.08 lb = 5.025 kg

This is 9 grams over my individual part list, so I'm fairly close.

Were I to want to shave the extra 25 grams, the seatpost or handlebars would be obvious targets. The handlebars (Ritchey Pro, 231.1 grams) are particularly beefy. Schmolke would knock a tidy 100 grams off in one, albeit very expensive stroke. But carbon bars would violate my $3.50 gram target for mass savings (although I violated that on the stem: the blings gotta be worth something). And I like the Thomson post.

I could probably trim a bit from the Thomson clamp, but that sort of thing is always a bit risky.

Man you really took this bike up a few notches with those changes. That is a big savings on the brake cables/housing, plus seat.
You might as well keep breaking the $3.50 rule and get that bar, it's already the same shape-ish.

If you want to get it sub 5kg for riding up hills, you could get some control tech bolt on skewers for the hillclimb wheels. :noidea:

Then only other thing I can think of is the front deralluer. Would a braze on w/ a parlee clamp shave some weight or perhaps a DA or a campy FD?

Trim the bars?

Other than that it is an expensive looking 25g. Surely being able to say 'yo! my bike weight less than 5 kilos' is worth something though.

3t Funda and Alpha-Q gs-20 forks are both lighter than what you have and quite aero.

Not really my cup of tea as far as bikes go, but I appreciate the pupose with which it has been built and the crazy attention to detail.

My advice would be to buy a 400g bar for $15 and after you have that mounted you can safely buy the Schmolke bar.

You'll be out of $15, but 400g bars are actually a multi purpose component, you can hang stuff from it, hit attacking cangaroos over the head or mount it to a competitors bike at night.

That is brilliant

.

Anyway, I just recently did the cables. One step at a time. When people here meet their weight goal, it seems most of the time the bike appears soon after on "for sale". It's good to have goals

.

Actually I could solve the problem simply by getting my hands on an old set of Prima 199 Al bars. They were close to listed weight. Hard to find in 40 cm o-o though.

P.S. the skewers are a really good idea. I can't trim the bars as I like the lower hand position occasionally, and other than the wheels it's my general purpose racing bike.

Great build and a good primer on where weight can be sensibly cut while still maintaining usability.

+1 for the Ritchey Alu bars - I've gone back to alu WCS from WCS carbon for my race bike - way stiffer and more peace of mind.

Updates:

replaced Thomson cradle, seat clamp, and bolts with KCNC M5 hardware: saved 43.0 grams
replaced stock SL1 seatpost clamp (22.1 grams) with lightweight clamp from Toronto Cycles (11.2 grams) : saved 10.8 grams

I adjusted the "weighed" numbers by these numbers. Unfortunately my front Edge rim cracked and had to be replaced, and I'm waiting to get the wheel back: I'll have it soon.

Pictures to follow when I get the light wheel back on.
