Not directly x68 related, but I did swap my wheeltop calipers for Campagnolo. Also went from 160 rear to 140.

Weights-
Calipers-Campy 127, Wheeltop 150 (both with pads and hardware)
Rotors - Campy 123, 155   Shimano sm rt20s supplied by tantan - 350
Adapter (not needed now with 140) 12

So 135g saved.

Really nice difference in intial bite point and modulation as well, pretty much as documented here: https://weightweenies.starbike.com/forum/viewtopic.php?t=175550

Debating between an X68 and the SPCycle R088. With AliExpress promos I can get the SPCycle for about $260 CAD cheaper, anyone have thoughts if it’s worth springing the extra for the X68.

DFS crank installed
They have not written the instructions and said use Cybreis which did not work  ;D Elilee cranks instructions worked on the end!  ;D
Slowly but surely coming together!
Next to do get the calipers working and dial in the throw and reach of the levers!

TanTan is definitely dead for me.

I paid 56 working days ago (!), 21 days ago I was told that they painted it wrong and now have to produce a new frame in UD matt.

I have NO delivery date yet.

Vivian is sending BS mails and is no help at all, just offering me a refund (exchange rate €/$ has dropped 10% in the meantime; postage costs are no longer split between 2 frames).

Total joke, TanTan never makes the frames themselves, otherwise it would be much quicker to sort out.

Did you order the frame in one of the colors that were available for selection other than a basic black? Or did you order a special colour?

I am asking because I ordered a prebuilt bike in (pearl) white which is a colour you can directly choose but got hit with nearly the exact same message as you did as well.

Should be
1X Transition's spacer for frame
3x10mm spacers
1X 5mm spacer
1X Handlebar transition spacer


So that’s 35mm of main same as genuine SL8.
They don’t supply one of the slammed spacers like the real thing.
Why do you ask

Kind of seems like the guy doesn’t know what’s up and is just reselling
Crankarm looks fine though, but the bolt is a bit frayed, or is it the lighting?

50mm I would say maybe you need a bigger frame which has a higher stack meaning less spacers.
What size frame have you ordered?

Custom paint which was done after 35 days.

Yesterday I got told that they finished a 52 in BLACK matt (was supposed to be UD matt so another failure) which took 21 days.

DFS claim to manufacture this crank and even supplied test data for stiffness.
When I contacted them directly, they mentioned they hadn’t yet produced installation instructions, as they were in the process of moving premises. I did point out it’s not ideal selling a crank like this without proper instructions!

They initially said to use Cybrei’s instructions, but after installing, it was clear those weren’t suitable. In the end, I followed the Elilee crank instructions, and that worked — the main issue was just getting the spacers installed correctly.

As for the bolt, it’s absolutely fine. I’ve had to take the crank on and off a few times, so what you’re seeing is just some black paint worn off the outer edge.

Yeah saw that chart on their page.
Interested to see if you can confirm this when you have finished your build.
Thanks for your info.
Was curiosity about the bolt because the one lexon supplied with theirs was a bit soft.

No problem
Probably took the bloody crank off 6-7 times yesterday  ;D but all is ok.
Will get the trusty old sharpie out to touch up  ;D

I tried modifying the saddle clamp and rails with yokes, but it didn’t work out.
So, I mixed and matched parts to reduce the weight—used the carbon cradle and one of the titanium M5 bolts on the back.

The seatpost weight is now down from 168g to 153.5g.
I've ordered an M6 titanium bolt from AliExpress to replace the stock front bolt on the clamp.
I'll also trim about 30mm off the seatpost, bringing it down to 350mm—the same length as my Darimo post on the SL8.
