Hi, I'm slowly building my frame up but struggling to figure out how to install the shimano di2 battery. Any tips or is there a battery retention mechanism I'm missing?

Thank you

You clamp it in the seatpost with the clamp you got, similar to this https://www.ebay.com/itm/389512002262

Does anyone know or can measure the crank bolt and extractor cap thread size, is it the same as sram dub? (M18/M30)

Normal for ztto, among other things I discovered that ztto and Goldix are both produced by Sunshine, so I thought Goldix was better? Maybe you can save yourself with this Goldix cassette https://it.aliexpress.com/item/1005009145670643.html but at this point I don't know which one to go with

Think that goldix is the same as ztto, same riveted construction.
Will probably get dura ace and be safe.
Going to ultegra from ztto seems like my bike weights a kilo more than before 🤣

Just realized my ztto ult 3 (all steel) has one tooth broken, after about 6000km, the shifting is still good but im putting ultegra back, until i find something lighter

Finally built the bike up, did battled with the internal cable routing ( but that's on me for wanting to use a mechanical groupset and setting up the brakes reversed the first time).
Haven't been able to do a real ride on it, just around the block but it seems way more comfortable that I was expecting, I'm coming from a Look 586 with Cosmic all carbon wheels.

For the curious ones the bike setup is as follows:

Frame: SC-R55D - BB86.5 - Size 510 (was weighing 900g bare frame )
Wheels: Tagoola - Aeroraptor 60/50 (1230g)
Handlebar: Lexon thin line 400/110 (320g)
Seat: Ryet G01 (100g)
Groupset: Shimano 105 - 12 Speed Mechanical
Crankset: Goldix 53-39T chainrings with CRUZBIKE (Titanium axle)
Cassette/Pedals/Chain/BB: Dura-ace (cassette 11-30T)
Disk rotors Shimano (not sure the model)
GPS Bracket: Zrace titanium
Bottles: AhyKa Aerodynamic

Bike as it stands in the photos is 7KG

The objective was to take it to below the 7kg with all, maybe when I move to a 1x I will be able to do it.

Looks good, can you take a photo with the bottles on the bike, interested to see the downtube to bottle transition

I have rockbros dub crank and my bolt broke when removing the crank, however i replaced both bolt and extractor cap
I used cybrei gp3 replacement bolts and they are the same as rockbros

This Ryet RS OSPW is actually really good because it has properly sealed bearings. I've done about 1000km often on wet and dirty roads with it now and it spins like new without any need for oiling and stuff. I didn't open or measure the bearings but they looked like some standard sealed bearings from the outside.

https://de.aliexpress.com/item/1005008456209648.html?

They are 607 2rs

On my rockbros dub crank the bolt diameter is M16, and also i think cybrei dub crank is M16

How much do these chainrings cost?

They seem same as leese from alix, anyone tried those?

Has anyone from far east copy... took inspiration, from infinity e3 saddle
Its used a lot by ultra endurance cyclists, but the price is a bit insane...

Hi everyone, I'm almost done with the assembly, but there's a 1 mm play in the fork and I can't seem to fix the problem. I've attached a few photos of the setup—can anyone tell me if I'm making a mistake somewhere? Thanks a lot!

It seems like you dont have any gap between the frame and your bottom cover, spacer whatever its called.
https://ibb.co/bMwN4H9x

To preload the bearings you need a gap there, you can try sanding the bottom part of the cover a bit and try again

Put about 5000km on this frame, maybe about 2000 outside, 3000 on trainer

Had a minor fall so i had to replace derailleur hanger and pulley cage, bike is fast, dont feel like the frame is holding me back.
I do notice its a bit harsher on the front than any previous bike i had, not sure if its fork, handlebars or whatever else, but its not the end of the world

Anyone tried rockbros carbon crank?
