The M5 screws that come with the ZTTO kit are 30mm long.
For the GR029 M5x35mm bolts should work perfect.
I will get them this week to fix the rear break mount.

Hello Dmitry

Unfortunately still no long ride with the bike due to snowy conditions here in Switzerland. I guess that the current weather is comparable to NY at the moment.  ;-)
But the shifting feels crisp so should not be an issue. The Zrace brakes are the thing that I am more concerned with, they definitely need more force to activate than Shimano Hydraulic discs.

Thanks for the compliment she is really happy with the bike, especially with her chosen colours.  :-)
The full bike weighs in at 9.06Kg, with some lighter wheels this could go below 9kg I guess.
Unfortunately I did not weigh the 11-46 cassette separately. But it seems to be pretty light for this size.

I recently bought a super light Zrace 11-34 Cassette that weighs in at 230g Vs. 306g of an R7000 11-32 Shimano.
So some of the Chinese parts can offer a weight advantage. The durability needs to be proven in the coming season...

I installed the Zrace 11-34 on my Merida Speeder which I modified to a Gravel bike.
I bought Elite 32mm x 35mm Carbon Wheels and 35mm Panaracer SK tires to complete the build.
The Merida comes in at 9.17Kg including pedals.

Looking forward to see your Trek finished with the 1x setup, curious about the weight when finished!

Hey that looks great and the weight is quite impressive for a bike of this age.
The stickers on the wheels are a bit too flashy for my taste... but sometimes it is a pain to remove stickers if the manufacturer used a sub par glue.

What kind of wheels do you have on order?
I hope some Chinertown conform species...  ;-)

The Emonda SL frame also sounds interesting, what groupset do you plan to use?

Have a great weekend!

The 38mm Ican wheels sound like a good choice. I had good experiences with CSC and Elite wheels so far... all three sets perform well without any problems over several thousand KM.
I opted for Novatec 411 hubs which allow me to adapt to my 15mm diameter forks. One set I got with DT Swiss 350 hubs during sale at a good price.

Shimano R7000 is the budget king IMHO if you want to stay in the Shimano world, not for behind the Ultegra R8000.
I did not yet dive into Di2 and stayed with mechanical shifting. As mentioned before I got my first Chinese cassettes to try out so no experience yet.
They look good and are light but time will tell how good they really are. ;-)

To remove stickers you can try to heat them up with a hair dryer of hot air gun (maybe remove tires first) and then remove the remaining glue with glue stripper that you will find in your home improvement store.
Usually some elbow grease is required if the manufacturer used nasty glue...

Looking forward to see the progress of your project, have a great Sunday.

TanTan (Lisa) are sending out the spare derailleur and handlebar spacers via EMS. I might wait for spacers to arrive. China Post are predicting 2 weeks. We are in 5km from home lockdown, so I wont be able to do much cycling until 5th March.

I was wondering which headset bearing is on the top and bottom of the Fork? the wider one or the narrow one?
The internal wiring is very difficult. I am waiting for a better bottom bracket than the Zrace one.
I assume that you get the internal cabling working before inserting the Bottom bracket. The front derailleur is tricky with the wire protruding from the frame. There is a small allen key bolt on this. Do you tighten it?

Here is an early picture.
