I would really advise against getting anything from OG-Evkin. I have a cracked BB (after only 500km) so I asked about warranty and the seller (OG-Evkin Official Store) is very uncooperative.
It has been going on for more than a month now but is is just a series of false promises and long silences from their side. Very frustrating They have been promising a new frame for weeks but nothing concrete... I have mails Aliexpress customer service 2 times and it looks like they are a little more prone to answering the days after that.
The latest communication was last week and they said it would be shipped this week (they have been saying that for weeks. I will have to pay for shipping). They have not been answering messages since then so I am not getting my hopes up. If things would change I will keep you updated.
