New getting to work and around the city bike

Hi there, here’s my fresh commuter (needs a bit dialing in and a shorter stem)
For the frame I used early 2000s Al frame (I think it’s some smaller German company) because I wanted to have disc brakes. These are I think the first Shimano 105 disc brakes. I used Shimano Sora brifters with older Shimano XT derailleur. 27,5 Wheels Alex rims and Novatec hubs, 1×9 for the moment
