Hey guys !

Been reading the forum for a little while and im now ready for my first build.
I have a few question i would appreciate help with.

Here is the planned build:
Frame: Tantan X-21 , considering Velo Build VBR-R-168 which appear to be the exact same bike or the Workswell R268 Disc to a lesser extent.
Shifters: Shimano 105 R7000
Front Derailleur: Shimano 105 R7000
Rear derailleur: Shimano 105 R7000 GS
Crankset: Zrace HardRock Road Crankset 170mm 52-36T
Casette: Shimano 105 R7000 11-34T
Chain: Shimano CN-HG601 11 Speed Chain
Brake: TRP Spyre SLC, now considering the Zrace as well.
Bottom Braket: Im confused on this one, what ever fit BB86 lol, maybe someone can make some light on this for me haha.
Wheels: Elite wheels SLR 3.0 Disc (Already have SLR 3.0 Rim on my current bike and love them)

Im open to suggestion regarding every piece of equipement.

Detail:
X21 is 600$ US, and VBR-168 479$, they both appear to be the same frame ?
Tantan do sell the R7000 groupset at a good price.
Im not sure which size i should get since according to there size chart i would need something in between 49 and 52.
95% of my use will be on the road, but i choose this specific frame because it can accomodate 32c tyre, and im planning to get a 2nd pair of wheel and put 32 tyre on there so i can use this bike for some light gravel as well.

I planned on building a bike for a while now so my Wife got me those tools for Christmas:

And

Do you think ill be fine with that, or is there anything else i need to get in order to complete the build ?

Also i was looking at a Workstation to make the whole process easier, but im reading online that we shouldnt use those with carbon frame ?
Im reffering to something like this:
https://www.amazon.ca/-/fr/Bikehand-Support-r%C3%A9paration-pour-v%C3%A9lo/dp/B07R452R8K/ref=sr_1_10?__mk_fr_CA=%C3%85M%C3%85%C5%BD%C3%95%C3%91&dchild=1&keywords=road+bike+workstation&qid=1614207228&sr=8-10

I dont know much about mechanic but its my motivation to do this build, i hope to learn alot in the process.

All Help is welcome, sorry if my english is perfect, its not my first language.
Thanks !
