Unless they are a 60 year old boomer they should fit on a 58, i'm 192cm and can even ride a 56cm with a 140mm stem and that is with me having my saddle quite far forward over the BB. 60cm is freaky large imo.

Bearings from any highly reviewed seller on aliexpress should be fine, especially for headset, for the love of god do not buy ceramic though, the longevity on them is a joke.

Again I'm just looking for a Chinese friendly local mechanic(s). Not interested in investing time/skills/tools/money into wrenching modern bike.

Why don't you just call around? My LBS says he will work on literally anything, see if any of your LBS have that on your website. Some mechanics also charge a flat per hour rate when they're working on unknown components.

pedals and cleats are one of the few things I would not advise buying from aliexpress.
Pedal quality is very important to fit and having one pedal being even slightly wider/shorter can really mess you up.

I've used aliexpress shimano lookalike cleats and they have fallen apart like a ride in, when I investigated them as well the stack height was significantly off the actual shimano cleats I had.

Not many people post photos of their completed bikes on here, but I always enjoy the posts. So I wanted to post my recently completed build on here, and share how much I spent. A lot of builds on here are really balling on a budget but I really purchased from mainstream vendors for less sketchiness, build came out to $3,288 assembled by my LBS

Mechanics first "Chinese" build at the bike shop, he was very impressed with the quality and noted that the internal cable routing gave him no problems. All of the workers at the bike shop where really interested in the build and none had ever heard of Winspace. This really shows how obscure this forum is, we are so far away from mainstream. He did ride it and was super impressed with it, I told them how my goal was to create an entry level roadbike, but have carbon wheels at the same price point.

8.1 kgs with everything, 17.85 lbs

Frame: Winspace T1550 ($1230 Black Friday)
Wheels: Winspace 2023 Hypers D45 ($1049 Black Friday)
Bar: Winspace Zero SL 380 W 105 L ($171 Black Friday)
Groupset: Shimano 105 R7120 Disc ($688 Merlincycles)
Tires: Conti GP 5000 ($130)
Tubes: Ride Now TPU 36g ($25)
Seat: Specialized Power Comp (Free: Old Bike)
Pedals: Shimano 105 SPD-SL (Free: Old Bikes)
Shop Assembly- $240

Just out of curiosity what country?
I have a feeling that winspace and chinese brands in general haven't penetrated the non english speaking market as strongly.

Any info on the price?

As the title says: Velobuild.

But tbh, i like their stem. Not too heavy for a stem with integrated hoses.

yes i realise this one is from velobuild but i mean where did they get the original design from? velobuild isn't making original moulds.
