[@cbb3062]

Pretty nice build, very cool wheels too one peice spokes!! One question though, any reason you went with shimano over sram?

[@GCPerformance18]

I like shimano better for shifter ergonomics

[@cbb3062]

@GCPerformance18 they do 100 percent honestly I feel like shimano shifts a tad better too. I just like sram for tge removable batteries so I can ride with a spare but other than that shimano is better.

[@Ghostina1]

I just bought Campy rotors for my SL7. I think they're the best looking rotors, and two Campy rotors were only $120 total. That said, your SL8 is bellissima!

[@antoniosanto2617]

Ciao mate, I’m looking for some videos/info about Alugear chainrings because I’m going to change mine with new ones. What’s your feedback about these chainrings, are they 100% compatible with Shimano original ones? And in terms of weight?

[@GCPerformance18]

yes for the 1x they work no problem I have some good miles on them and i can say they are one of the best 1x chainrings out on the market for the performance and weight

[@HappyYouTube265]

Amazing bike. Great build, well done. Is the white here the same as the S-Works with the sort of pearl color to it?

[@davidcarino6500]

Nice weight with everything on it. Thank you I have a Trek SLR, similar in weight but I'm looking for lighter wheels then maybe 15 lbs for mine. Awesome build 👌🎉

[@GCPerformance18]

I got it even lighter since then, might do a follow up video on it

[@antisha82]

But you can not climb on this bike with this chainring, what is use of light bike if it's not made for climbing?

[@kimwarner6050]

You can still climb. Especially since he has a 34 at the back. Besides he could just switch to a smaller front chainring if he lived where mountains were. I run thous same setup with 46 chainring and 11-30

[@antisha82]

@@kimwarner6050 Yes you are correct, probably its all flat where he rides so no need for extra chainring, very nice bike he did

[@leepipes7336]

are your frame boost? ive seem that alugear has 3mm offset

[@GCPerformance18]

my frame is not boost

[@super8hell]

I run 1x on my roadbike too, with Alugear on Ultegra 165mm cranks (somehow the chainline is better than with 1x SRAM cranks). I have SRAM Rival 11 speed and xx1 chain is indeed the optimal solution. Tried different chains, Flattop, KMC 1x, and XX1 felt the best at extremes of the cassette. Not a huge fan of SL8 but i'm digging the stormtrooper look.

[@jtho27]

Have the same experience. Alugear chainring is more noisy than Sram. I don't know but the size and shape of the teeht resonating with that arochainring is a bit much takatakataka for me when going to the extrems of the casette. The Chainline seems to be a little more outward too...

[@super8hell]

​@@jtho27 I agree about the slightly more outwards chainline. My suspicion is that the teeth on alugear are also slightly thicker and longer. This and and the subpotimal chainline creates the racket especially on the easiest gear (50-42 in my case). Never dropped the chain though.

[@JayLato]

6:06 my dura ace crank matches great with 105

[@GCPerformance18]

im telling you its the easiest wayyy

[@Adub101]

Grant what is the weight of the 160 Carbon Ti rotor with the adaptor?

[@GCPerformance18]

I forget the exact amount but It was like 9 grams lighter then an xtr rotor

[@mengai1967]

Would you put Craft Racing Works wheels on your SL8?

[@GCPerformance18]

Yes I would

[@galenkehler]

Great build! That's a beauty. Side note: why on earth are 3d printed saddles more expensive? They should be dirt cheap if they're just printing them out of a machine.

[@GCPerformance18]

yea I have no idea, as soon as you put it out that it is 3d printed the price tag goes up lol

[@patrickparisienne1917]

Because of the time each machine takes to print each saddle as opposed to regular production methods.

[@Penalist]

Development costs, machine production costs and price of ‘novelty’ (much like ‘aero’ in the recent past came at an additional price).

[@mlee6050]

@@GCPerformance18 I find most 3d printed stuff they charge at 400-700% of actual cost to make

[@padraigmoran5710]

How much did your Ultegra / Dura Ace Combo Groupset cost in total?

[@GCPerformance18]

I got it for employee purchase so I don’t know the exact but for 1x it’s pretty cheap

[@padraigmoran5710]

Okay nice. From looking at your build, it appears the Cranks and Cassette are the main parts which you would advise upgrading to Dura Ace (or another) instead of Ultegra? Would you have any other advice for maximising performance/value?

[@user-cx2bk6pm2f]

Looking good. The bar tape, though... it doesn't match anything.

[@GCPerformance18]

yea I am thinking of changing it, it is very busy

[@potenzaintertradeco.ltd.6970]

Did you had any chain drop and chainring flex, during high wattage sprints with alugear ? I heard that their double chainring are not safe and possible injury. Can you tell me about your single chainring experience

[@GCPerformance18]

single works great I dont have any chainring bend on there, and my sprints are only 1100 watts but maybe under long climbs and havey watts but honestly i have had no issues

[@christophesiegel]

Why not Princeton wheels ? Price ?

[@attiemo1665]

Is the tarmac considered to be an all rounder racey, climbing and endurance bike?

Good looking bike, why did you chose Specialized exactly? Not Trek or Scott for example, just curious

[@derfx89]

Does the Dura-Ace 1x use special teeth or chains? Is it like a DIY, stripped 2x or a Shimano design? Never seen that before on a road bike

[@olegkurovsky3198]

For the mountains you'd need a heavier cassette and a dual chainring in front. So you actually need an S-Works for 6.8 :) Otherwise - great looking bike! Also, the build video is the best I've seen so far!

[@mlee6050]

I got planet x rtd 90 frame so £400 frame, less than £4000 to have 6.7kg, yes I could maybe go 6.3kg without lower rider limit under 120kg, forgot 2x too

[@echtogammut]

The SWorks they wouldn't dare give you a miscolored spacer, but the Pro they would? That doesn't make any sense, the spacers should be a common part bin part, they clearly had a bad batch run and I would imagine some SWorks bikes probably also got the same almost black spacers, assuming they all are boxed in the same factory. This is a slick build. I have a special place in my heart for white bikes. My first road bike was white with exposed carbon fiber and I went with similar setup for my Colnago. I'm trying to find an excuse to buy those wheels.

[@GCPerformance18]

I think I might have explained that wrong, the spacers I got from the handlebar company they are there own company an d make there own spacers 3dprinted, so one was mis matched from the company I hasve never seen specialized spacers wrong

[@gb4408]

Since its 1X you should try Rotor rings

So all the cool kids are turning their hoods in now.😂😂

[@GCPerformance18]

of course lol

[@bengt_axle]

Are these integrated cabling bikes compatible with ordinary stems and bars? The reason I'm asking is because I want to know whether you can ride these bikes with an ordinary cockpit setup, and extra hose and cable length externally routed along the bars and headtube, so as to be able to try different positions by swapping out the stem and spacers and doing test rides. Once I'm sure of the right position I'd order the right integrated bar and route the hoses through as shown here.

[@yonglingng5640]

It all depends on the bike's spacer kit. If it was designed to be cockpit-universal, then that model can take any cockpit. Some examples include: Specialized Tarmac SL7 Third-generation Venge Second-generation Allez Sprint Trek 2021+ Émonda Second-generation Émonda ALR Sixth-generation Madone (only if it's running the Émonda's spacer kit) Cervélo Second-generation Soloist Any model with integrated internal routing with an FSA-branded headset (cockpit-universal FSA spacer kit sold separately with some models)
