This is the same frame (model) as Carbonda 909, but produced by another company - Ican (https://icancycling.com/, https://www.icanbikes.com/). In my opinion, the quality of the Carbonda is slightly higher (I have the Ican S2 model, which is the 936 model of the Carbonda), but the Ican products are cheaper. Some of my friends have been driving Ican S5 for several years and so far everyone is happy. Previously, these frames were not sold on Aliexpress, but now they have appeared.
