Good old Aluminium will keep an eye on mine! where did it snap right through the middle?
Also if you can send me links to alternatives I have see Ti option which will obviously be better
Here's an assortment-https://www.aliexpress.us/w/wholesale-carbon-seatpost-cap.html?spm=a2g0o.home.search.0  Haven't weighed or tried one yet. And yeah, I saw ti parts or someone had ti yokes...

Keep in mind that I drilled mine to clear the 6mm bolt-yours with the 5 is likely stronger, but there are reports out there of them breaking with 5mm bolts. Mine snapped on one side of the hole, but might as well been dead center.

So, I've been lurking here for some time and sometime in early May I placed an order for a X68 with complete Ultegra di2 groupset and a set of 50/65 Falcon pro turbo from Light bicycle. The wheels are 34mm wide and I run Conti GP5k 30C that expand to 33mm. It is absolutely not a weight weenie build, focus has been on a mix of aero and comfort for endurance riding without explicitly trying to weigh the bike down.

Heu, can you share a link to taillight mount you have mounted on you seatpost? I'm looking for something like that, couse my rubber mount pissing me off. Thanks

i have this one https://makerworld.com/models/599359, if you have 3d printer you can make it pretty cheaply. I printed it in ASA and it works amazingly.

Np, looks good! :)
Unfortunately, there are no good free Garmin mount models for the roval rapide cockpit. You could try this one: https://makerworld.com/en/models/575072-garmin-mount-for-integrated-handlebar, but in my opinion, it's not the best. I just ended up getting the mount from the guys over at https://www.magcad-designs.com/. They have really nice designs, and the quality is fantastic.

Thanks to Sander2177 for the information I needed regarding the legitimacy of websites and contacts. Unfortunately, my local bank declines purchase made via PayPal. However I was offered an alternative to complete the transaction directly to: tantan168vip@yeah.net is that a safe way? Sorry for my exaggeration, it's a significant amount to pay, I want to be sure.

Hello Guys,

Here a picture of the 2 bikes I built for my wife and I. Fork was the heavy one.

For her:
- size 49 + 90x380mm
- color YS3481 - blue
- ZTTO BSA Dub bottom bracket
- shimano 105 di2 12s
- cassette Dura ace 12s (got it from a friend) - 11-34
- chain Dura ace
- Riro carbon crankset - 165mm - 50-34T
- Tagoola wave 2 wheels + 32c GP5000 s tr + orange seal
- III3 pro disc rotor 160mm front - 140mm rear
- Ryet 3d saddle
- IGPsport BSC200s gps

For me:
- size 58 + 100x400mm
- colo YS2086-1 - green
- ZTTO BSA Dub bottom bracket
- shimano 105 di2 12s
- cassette dura ace 12s (got it from a friend) - 11-34
- chain Dura ace
- Riro carbon crankset - 172,5mm - 50-34T
- Tagoola  wheels 40mm + 32c GP5000 s tr + orange seal
- III3 pro disc rotor 160mm front - 140mm rear
- LFZ pedals
- Ryet 3d saddle
- Garmin 1040

it was fairly straight forward to build as it is my first build I had to discover how to use the different tools but overall pretty easy to do.
I used the SL8 user manuel to install everything.

Only down part tantan forgot to send the Seatpost wedge cover for both bike, so I need to check with them to send them.

last point I need to put carbon paste on the seatpost has it is slidding down a little even at 6,2Nm.

I did 70km with the bike and I am very impressed, coming from an aluminum decathlon triban 3 from 2013, it is a completely new feeling and sensation.

Ahah yes it was the last point, but she was out of the house when I finished her bike, she now tried it, and we adjusted the lever properly  ;D

I already follow this thread for a long time and I am aware of the issues in the past. However it seems to be hard to find another frame which is light and still is quite aero like this one.

Will the XM Carbon Speed wheels with 26mm internal 34 external paired with a GP5000 32mm fit in this frame?
Did anyone ride light gravel with this frame?

HI,

Did you weigh both bikes?

My 25mm inner width wheels with 28mm tyres measure 31.7mm.

On my XMC wheels with 24mm IW, the same 28mm tyre measures 30.7mm.

Personally, I wouldn’t run a 28mm tyre on 26mm IW either. Even the 28mm on 25mm IW feels borderline to me—unless someone can prove me wrong.

A 30mm on 26mm IW might work if some has tried it, I think a 32mm would probably be too tight for my liking.

28mm tyre on 24mm IW → ~30.7mm
28mm tyre on 25mm IW → ~31.7mm
28mm tyre on 26mm IW → ~32.5mm
30mm tyre on 24mm IW → ~31–31.5mm
30mm tyre on 25mm IW → ~31.5–32mm
30mm tyre on 26mm IW → ~32.5–33mm
32mm tyre on 24mm IW → ~33–33.5mm
32mm tyre on 25mm IW → ~33.5–34mm
32mm tyre on 26mm IW → ~34.5–35mm

Depending on tyre model I run maxxis High Road SLs
