So I just got my frame delivered, took quite a while during the holidays in germany. Do you need some Screw measurements or did you receive yours now?
Quite happy with mine, the paintjob looks really good, just the brake mounts are sprayed over quite a bit.

The adapter for front brake is not good, one counterbore is way too deep so I can't use it. You guys reckon Tantan will send me a replacement or just don't bother and get it somewhere else?

How long was your delivery time and what was the final price you payed?
@all is there any kind of promo code available right now? Couldn't find anything on the web.

Does anyone here use the Magene L508 radar mount? I have one, but only for the Varia, and there the central insert has a horizontal oriented slot for the mount (for Magene should be vertical). Can't finde anything on aliexpress

Search for KOM cycling garmin to wahoo adaptor. Not on ali, but maybe you can find similar.

If you already have the mount, try searching for a magene compatible insert on Ali that has the 2bolt fixing,
Costs next to nothing and is rock solid, did this on my mount for a dogma f seat post.

Something like this.

@dovh here 3D printed an adapter mount for his Magene radar, works pretty well.

Hi,
just small reminder: keep in mind that many Varia holder (3D prints) will crack or brake after some time, unless they include some glass fibers.
3D itself does not stand so well all the vibrations. And saving 20€ against loosing Varia radar is not something to miss=)

I printed this holder in polycarbonate filament and it has held up amazing, done around 4k km with it and no issues what so ever. - https://makerworld.com/en/models/599359-tarmac-sl8-garmin-varia-mount?from=search#profileId-526361
and for my magene light i use a simple garmin extender since the magene light is rotaded 90 degree when you put normal adapter on it it will create a correct mounting for garmin varia. I use adapter that i designed, see screenshot of it.  (if someone wants it i can share the print files)
edit: here is the 3mf file for the adapter - https://drive.google.com/file/d/1Jiz3ll-n4ATH84sOZFS_2NL1Htc-f3Xg/view?usp=sharing

Looks good to me!

Anyway you could share links of products you've used and bought which are not from well known brands?

I just received by x68 and there appears to be a carbon fiber lip in the seat tube that is preventing me from installing my DI2 battery far enough down in the tube to adjust my seat height. I suspect this is where 2 different carbon parts were joined together.

Is this fixable? I think cutting my seatpost shorter and drilling new di2 holder holes will not get me the minimum depth required.

Try searching for the gcn video of the R088, there they show you a possible solution

Yeah, the threading for the bottom bracket on the right side became loose, got a lot of radial play..


Seems like universe wants to punish me for buying chinese fakes :D
