52cm Specialized Tarmac SL8 Onyx Blue - 6.14kg

[Aryeh]

I decided to start a thread for my 2 month old non S-Works Tarmac which replaced my Cervelo R5.
Using mostly the same components, so far the Tarmac is over 150g lighter.
I have a full part list but I did not weigh everything.
The groupset and the wheels moved over from my R5.
I wanted a light bike, but I did not want to spend an extra $2000 to save 100g.
The weight is 6140g including the pedals, computer mount, radar mount and bottle cages.

Frame: 52cm Specialized Tarmac SL8 - Blue Onyx
Wheels: Farsports Hyper 50mm with RD270 Hub
Tires: Continental GP5000 TT TR 25mm Front and 28mm rear (set up tubeless with 40ml of sealant per tire)
Levers: SRAM Red AXS with carbon clamps and Ti clamp mounting hardware.
Brake Calipers: SRAM Red AXS with Alloy backed pads.
Front Rotor: tipartstitanium.com 160mm
Rear Rotor: Galfer Wave CL 140mm
Crankset: SRAM Red AXS Quarq 48-35T 170mm
Pedals: Speedplay Titanium
Bottom Bracket: BBInifinite BSA Ceramitech
Chain: SRAM Eagle XX SL
Cassette: SRAM Red AXS Rainbow 10-33T
Saddle: Gelu E1
Seatpost: Darimo 250mm 3k
FD+RD: SRAM Red AXS with HiCycle Carbon batteries
Barstem: Avian Canary 360x120mm
Expander: Cane Creek eeNut
Top cap: 2.5g integrated cap with bolt from AliExpress
Bar tape: EXS Airtape
Computer mount: Alpitude Stelvio Correto
Radar mount: 3D printed
Bottle Cages: AliExpress 7g
Hardware: Bolts replaced for FD Hanger (Alloy), RD Hanger (Alloy), Seatpost clamp (Ti), FD Mount (Ti)

I have a Darimo inline seatpost and a Gelu saddle on order which should bring down the weight some more.

Looks great. Looking forward to a ride report and comparison. I think we all appreciate a good comparison between superbikes.

I already have nearly 1000 miles on it. I cannot tell the difference between the 2 bikes in any way. I thought the specialized would feel faster due to it being somewhat Aero focused but they feel the same to me.
I'm still really happy with the switch. I put over 20k miles on my r5 over 3.5 years and I wanted to try something new. I really like the way the bike looks and it rides beautifully just like my R5 did while also being a bit lighter.
I did my first ever 200k ride a few weeks ago on the new bike and it was really comfortable.

Down to 6265g with the XX SL T-Type MTB chain. SRAM are claiming it's not compatible with road AXS but the dimensions look identical to me and my digital caliper tells the same story.

great looking bike and great weight savings . it will be lighter than a standard s works complete bike with your upgrades and you still have a $1k in savings

The bulid cost for this bike is almost equal to what the Tarmac SL8 Pro complete bike costs which leaves me with over $5k in savings compared to the S-Works complete build.

Not exactly in love with SL8 but this one's hot AF. Really tastefully built!

whats your saddle height? i think i would also ride a 52, but i like a lot of saddle to bar drop, so just getting ideas.

My saddle is set 66cm from the BB. I'm 5' 7" or 170cm and I'm on 170mm cranks.

New Gelu E3 saddle arrived today.
It is 61g instead of the quoted 55g.
I will be testing it to potentially replace my 80g Berk Lupina that I've ridden for the last few years.

I have the E3 saddle on two bikes. I've also had, and broken, quite a lot of Berk Lupinas. Comfort is personal of course, but there is no comparison between the two in terms of quality IMO. The Gelu is streets ahead of the Berk. I find the Gelu very comfortable, but it has noticeably less flex than the Lupina.

I had one Gelu crack on me. I was offered a crash replacement with a reinforced section where the previous one crack. Anghel is great to deal with and replies fairly quick.
