I just bought an S-Works Tarmac SL3 50cm to race on next season. The goal is to get it down to 6.8-7.0kg with an aluminium stem and bars installed. Should be possible.

Parts:

Seatpost: Bontrager XXX - 170g
Saddle: Selle Italia SLR Kit Carbonio Flow - 128g
Bars: Zipp Service Course SL 38cm - 250g
Stem: Zipp Service Course SL 110mm - 125g
Wheels: Fast Forward F4R DT240s - 1325g including quick releases
Tubes: Have not decided yet
Frame: S-Works Tarmac SL3 (50cm) - 1050g
Fork: S-Works SL3 fork - 380g
Groupset: Ultegra 6800 w/ 14-28 cassette (including cables) - 2519g
Bar tape: Lizard Skins 1.8mm including bar ends - 55g
Bottle cages: Tune Wasserträger 2.0 2x - 28g
Pedals: Dura Ace pedals - 250g
Garmin mount: 28g
Headset: Cane Creek Carbon Headset - 115g
Fork Expander - 45g

Weight: 6.468kg without tubes on. Which tubes would you recommend for racing? I ride Vittoria Corsa G+ clinchers now and was looking at the same option as tubular (265g per tire). Bike would weigh in at 6.998kg with those tires.

Yeah, the frame isn't 850, probably more like 1050, but that still leaves 400g to find, which I can't, looking through your list, which seems correct. Are you sure your 'big' scales are correct? 7kg sounds about right to me.

Did you weigh all of these or are they factory weights? Also missing in the list: quick releases and cables.

Weighed in the bike shop on a Park Tool scale. 1050 sounds about right for the frame. 850 was something I found somewhere on the internet.

I weighed some of the parts myself (saddle, seatpost, wheels, tires, inner tubes) the rest are factory weights. Quick releases are included in wheel weight and I think the cables are included in the weight for the total groupset.

Groupset weight doesn't include cables and housing.

Typical cables n housing 200g thereabouts.

SL3 sworks frame should be around 1kg. Despite being branded sworks, it's not the lightest, if you compare to other brands. For equivalent vintage, the evo hi mod is definitely lighter.

U should be able to hit 6.8kg easily with some modifications

I would check it on another scale if I were you. Don't you have a scale for weighing people at home?

Are you sure about the wheel weight including quick releases? Vittoria list them at 1576g for the pair. Normally listed wheel weights don't include rim tape (if required) and quick releases.
You've listed them at 1576 bang-on manufacturers claimed weight?

Fork expander isn't listed - they can be 30-40g, and topcap and bolt.

Basically you need to weigh every single part to find the discrepancies.

its really amazing how much the little parts add up to be...like the expander and top caps...bar ends, handlebar tape, etc.

Think I've got it right now.


Seatpost: 3T Stylus 0 Team Carbon Seatpost - 195g
Saddle: Selle Italia SLR Kit Carbonio Flow - 132g
Bars: Zipp Service Course SL 38cm - 250g
Stem: Zipp Service Course SL 110mm + top cap/bolt - 142g
Wheels: Vittoria Elusion Nero Ceramic + skewers - 1700g
Tires: Vittoria Corsa G+ clincher - 257g x 2
Inner tubes: Vittoria Latex - 69g x 2
Frame: S-Works Tarmac SL3 (50cm) - 1050g
Fork: S-Works SL3 fork - 380g
Groupset: Ultegra 6800 w/ 14-28 cassette + cables and housings - 2540g
Bar tape: Lizard Skins 1.8mm + bar ends - 60g
Bottle cages: Elite plastic cage 30g. Ordered some Tune Wasserträger 2.0's at 9g a piece
Pedals: Dura Ace pedals - 250g
Garmin mount: 34g
Headset: Cane Creek Carbon Headset - +/- 115g
Fork expander - 40g

Total Weight: 7.570kg / Weighed on person scale: 7.5kg, so that's about right.

What would you recommend for getting the bike down to 6.8-7.0kg? Still need some new racing wheels. Prefer to race with aluminium cockpit and think the Zipp cockpit is pretty light.

Now looking at FFWD F3R 30mm (1220g), 9th Wave Road-TSL50 50mm (1198g) and the FFWD DT180 Special 45mm (1200g). All tubular wheelsets. The 9th Wave wheels look like the best option to me; lowest in weight and price, and highest in rim depth. Have to decide on one wheelset that is suitable for racing in the mountains and on the flat.

My 58cm SW SL3 weighs just under 1kg. Maybe it was built on a good day or just the matte paint.

I really do not believe that Specialized ever put their efforts on a light bike. It would be interesting what they could come up with.
