Any recommendations for some weight reductions?
Wheels & tires: Many carbon spoke wheels would reduce weight by around 200g for similar depth but CRW seems like a popular choice. 2x Conti GP5000 TT TR should save around 100g and be faster.
Crankset: Red E1 (~305g) or D1 (~335g), Shimano rings (can use your existing rings and sell the heavy crankarms ~550g), and either a 8 bolt to 4x110bcd spider (~45g) or power spider (~105g [Sigeyi] to ~165g [DFour]). If you go power you can save ~100g on your pedals. This would require a BB change.
Saddle: Personal preference but there are many that can drop a lot of weight.
Rotors: Galfer can drop a lot of weight and work well for most. However if you frequently ride 20%+ technical descents I'd keep at least a front Shimano Ice-Tech rotor.

just first look and comparing to my setup
Bottle cages I have Elite Leggero save 50 grams
Cassette Duraace 11-30 saves 20 grams
Saddle I have Alpitude Gardena save 90s grams
Wheels I have Farsports carbon spoke 50mm save 200 grams
over your setup.

Ofcourse you be the judge on what's worth it pricewise!

You could always ride as is cause it looks badass and I'm sure it rides just as good. 7.1kg is "heavy" for ww but in all honesty, should be a delightful ride still.

Take my word with a grain of salt though. I'm less ww every day. Just raced Pescadero Road Race here in California last weekend. Seeing 20 year old kids ride away from me while doing 400 watts with their 8.3kg bikes puts perspective on things.
(Helps that they weigh 120lbs)
Thanks! Yeah you are right, I am no WW myself. It's a bike community for me and it has by far the biggest Tarmac Thread.
I ride near the Alpes and often do climbs only - if you do the math the weight basically does not matter. 5W are more important than 100g :D
And for the Cassette: even with a FTP of 4W/kg I don't fancy 34-30 on something like Passo Stelvio :D
The weight doesn't bother me, but I have the chance here to get down to 6.99kg :D that reads nice.

Can you send me a link/some pics to your wheels? I really do like the DA ones but I want to upgrade here.
For Reference: The main Goal was to build a Tarmac SL8 at a fair price point. I collected parts for like 6 months to build it as cheap as possible (you can't see it, but the build currently has Ultegra Brakes and STIs). Everything added up the build cost me under 9k€...

Thanks for the other tips guys, I'll take a look. Hopefully I can get some parts easy on the European market (for a fair price :D )

You can scroll down to take a look here at stevec1975's thread. He has a beautiful build. I have these exact wheels. Haven't taken any photos of them yet (just arrived last week)

Was worth the humbling and torture. Love that course / race. Ride that loop on the regular as well.
Already looking forward to next year.

Build ready!
Any recommendations for some weight reductions? The Garmin mount seems very heavy.
Currently standing at 7.1kg. bottle Cages are Leftover from my Aeroad. Looks quite nice and with 35g per Cage reasonable lightweight.
Very nice....is that a 54cm?

This is my build and currently my frameset is sent to the workshop for the custom paint job.
I'll start the build after it comes back. I've opened up a post for it. Can't wait to see the final weight!

Ti bolts for the bottle cages are heavier than the ones that come with the bike. The factory bolts are alloy.

I bought some Ti bolts to replace the stock seatpost bolts only to find out that the stock bolts were already Ti.

The factory rear derailleur hanger bolt is steel and can be replaced with aluminum. The front derailleur hanger bolts are either steel or Ti and can be replaced with aluminum.
The seatpost clamp bolt and barrel nut are steel and can be replaced with Ti.

I'm finding any bolt I can switch on the bike. Now I Found few but not all. Like bolt for rear hanger and roval rapide cockpit only.
Do you guys got the list of bolt spec?
