In 2023 I got my hands on SuperSix evo 2021 frame almost for free. Using local marketplace bought myself 11s 105 discbrake group, some shimano wheels and cannondale cranks. Stem, handlebar,chain,BB,casette,pedals,bartape and few other things straight from Aliexpress. It did work well and all with few ,,this,, and ,,thats,, and I was fine with this ,,cuz that price,,.
By the end of last year it came to say good bye to SuperSix and build something. Then it just became so clear that ,,What if put full chinertown style bike just for this What if part,,.
Some serch, plenty e-mails, few discounts and cupons later: Full carbon gravel that uses everything from china yet I couldnt decide for chiner groupset that was more expensive and less reliable than Shimano Di2 105.
Do I have a full support from them if anything happen? No clue but I'm fine with this. I knew I'm doing it for my ,,What if,,
Serch process was fun, building everything also. I'm glad I did it and breaking price everything was under 1900 euro which is more than 50% of known brand same spec or even lowe spec.
If you are ready that something may not go as good as you plan, just do it. I was ready for at least 50% things go bad or be just unusable yet almost all of those parts did me right from the beginning.
