Hello everyone,

This is my first post. I am hoping I will face a lot of friends here.
I am dilemma between this decision to make a custom project or to buy a ready one.

But lets we explain the stuff one by one.
I am from Bulgaria. I am high 177cm. The budget I set is around 800 euro. I am looking for a modern geometry (it's hard for me to understand and make a difference which are with old and new)
Should I go with 29 or 27.5?
I am a fan of Shimano so prefer it instead SRAM for example. Regarding the fork i would like to have ROCKSHOX 2019/2020 Air
If someone more advanced is already goes trough this path I will be thankful for his advises and help.

So on the topic.
List with best online sites I can buy parts. In the moment the following list I have found for me is below. Mostly I want looking for sites in Germany or UK
- Bike discount
- RCZ bikeshop
- Chainreactioncycles
- HiBike
- Wiggle

Ready bikes:
- Cube 29 CUBE ATTENTION SL BLK BLU (2020)
- ORYX NINE X22 29
