Well you might be right I will try with other pedals - I will keep you updated since I already greased and torqued everything I could on the crankset + the BB replacement changed nothing
No need to try new pedals for checking this. Just rubbing some candle wax on pedal mechanism at the back, plate and cleats contact points should confirm if the noise comes from the keo cleats

I have a creaking sound when pushing > 250W in the bottom bracket area
More a squeezing noise
Already changed BB with brand new Ultegra one : still there
Greased everything on my Magene P515 crankset
Still there
Happens up or down on the saddle
Pedals greased
I am getting mad
Just to check: What pedals and cleats are you using? I know it sounds stupid, but Look Keo are famous for that squeezing noise if not waxed. Also, not a slight rubbing from the FD cage due to flex?

Just a couple of things in case any of you want to build a light X68.
The Hy carbon seatpost from Ali works on my frame. Just a small piece of 3m frame protector where the clamp grabs and carbon paste, seatpost hasn't moved. Around 60g savings from original post and can be setup for 0 offset

And a revelation was the Ryet ultralight full carbon saddle advertised at 58g that came at 60. It is a copy of the Gelu for £60. 240x122mm and super comfy. I'm coming from a Selle Italia SLR Boost Kit Carbonio superflow at 130 width and no problems at all even in long hours on the saddle.
 Also Ryet 5.8g carbon bottle cage. Yes, the bottle slides in easily, but never rattles or dropped a bottle
 
Bike can be built lighter if replacing all bolts to Ti. I only done the most functional ones. Final weight all in 6.2Kg

Regarding the frame in general all is working well and no problems to report

Bye Bye X68...??

This is NOT a hundred percent confirmed. Someone on facebook group said it got told that on a reply via WhatsApp and the model disappeared from their website. So...I don't know?

So, definitely pulled off their sites, but Vivian says to get in touch via WhatsApp to order it offline.
I can smell Specialized lawyers around...

Has anyone here bought a full bike from tantan? How did the process go? I am thinking about buying it built.

I got quoted from Jessi 2546 USD for:
  • ultegra r8170 di2
  • 25 internal width rims 50 deep carbon (LC50C-31 Wheels with D238-spuer light-Ratchet centre lock 12s and Pillar 1423+SAPIM Nipples)
  • custom 165mm cranks
  • S775-1 pearl white paint finish


Plus 300 USD for shipping to europe.

That's a decent price for the full build. Yes, the wheels maybe a bit heavy for today's weight obsessed standards but no a big deal. Only thing to be aware of is that the chainset is a 105 instead of Ultegra, but again, better than getting stupid long cranks
My self built with custom paint, full Ultegra and Zen 40/45 wheels came at 400 usd higher than yours

Hi all. I've ordered the frame in July and received in september. I started building it this weekend and noticed I am missing the di2 grommets. I contacted Rose from Serpah/tantan and she told me this parts are no longer included in the packages. However, checking Patrick's video, you can see that at least the rear grommet is among the parts sent to him. Has anyone else had this issue?

I received the rear grommet for Di2 with my frame recently. I wouldn’t worry if that was missing. Easy to get one online for a quid or two

Do you have a special facing tool or did you use a file and/or sandpaper? Frame looks indeed very nice :)

Thanks. As I mentioned there are a few imperfections on the frame that a more expensive western brand wouldn’t have got away with it, but only cosmetic
You could carefully file away the paint, but to achieve perfect parallelism a facing tool is best
For the brake mounts I use the Park Tool DT-5.2 plus some carbide files and the tip for carbon not included in the set. Expensive bit of kit, but I use it a lot at the workshop
Bottom bracket reamer and facer also from Park Tools

No YS code for this one. There was a back and forth WhatsApp conversation with Vivian with a couple of examples. My frame is now on their social media, so just need to ask for this one.

Received my frame. Six weeks since ordering to UK
Size 52. 865G frame, 425G uncut fork in translucent blue. Dark until the light hits it. This is a mist of blue on a raw frame with glossy finish
Paint looks well done, no missing spots or anything. There are a couple of tiny dimples on the carbon here and there, as if no fillers have been applied. It seems only cosmetic and I’m not too worried. You’ll get what you pay for, some are lucky some are not. Apart from that, fork and all races look clean and smooth
BB with no overspray and threads all clean and good. Anyway,I did chased and slightly faced
Brake mounts as expected needed facing. All done, with before and after pics
Now waiting for a set of Zen wheels, carbon cranks from DFS and Ultegra groupset at some point. No hurry during winter
I can provisionally say the Hylix 15 to 0 offset fits. Only 0.20mm narrower that the Tan Tan post. I tested it with a set of wheels, no cranks and bouncing up and down full force without carbon paste
Fingers crossed it works since the inline post will help achieving the perfect fit

You need to contact them via WhatsApp. I paid 200USD for my paint, but there are cheaper colours

I got a Hy seatpost for the SL8 off Ali. 310mm 15 or 0 offset  Superlight but don't know if it will fit yet since my X68 frame is on the way!
So...useless comment at the moment

I would start from the beginning again. The fact that is working tells that there is a problem with the setup and limits. For initial installation look at the page for general 12 speed Di2. For 105 limits specifically:

Exciting stuff Sander. My wheels are in the making. Same specs as your 40/45 set but paintless and black hubs. Haven’t heard anything about the lack of XHs, so hopefully I got some of the last hubs in stock. Thanks for the help

Drum roll ladies and gents...The eagerly awaited video of the X68 build is up
https://youtu.be/WhVb730XtTk?si=oNdQMXci5oKyQyYV

Thanks Patrick for such a good and conservative initial review. Since my frame will be slowly making its way across the sea soon, I was waiting for this vid to come up
Two points to consider regarding the finishing details:
First, I'm not waiting to see if I'll be lucky or not with the brake mounts or BB overspray. I'll be getting my sand block, diamond files, reamers and facing tool straight at it. This is done to 90% of any new build coming into the workshop, and I know in advance that this one won't be the worst case. I have many horror stories of reputable brands and their expensive frames being well off, even the ones who say do not face, its been done before and bla bla...However, facing is not the final solution of calliper mounting/ rubbing problems. Too many forces at play when brakes are applied, from bolt thread squareness , pistons and pads play, correct bleeding  etc. Finally a good eye when mounting is essential

Regarding the seatpost, if it works with a bit of carbon paste great, if not, I wont be confident tighten it to 10Nm. In that case I would be looking at some 3M tape or alike reinforcement, or even a thin layer of carbon to wrap up the sloppiness
Once again, thanks Patrick!

What do you think of this one ?
Is that an x68 faced? Thanks for the pic. So if that far is required to achieve 68mm spacing it means Specialized also got rid of the sleeve lip. I'll be getting the Vernier callipers on it then. Cheers
