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

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

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.

They are 607 2rs

How much do these chainrings cost?

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

your fork still seems too long. Need to cut it shorter

No its not, its even cut too much, but shouldnt be problem for preloading

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
