Back in 2019 (a year ago) I made a video (https://www.youtube.com/watch?v=VUgo6uIdjtA) about the modifications I did on my Merdia Speeder 100 2015 model. I upgraded there from the original Tourney Crankset to a Claris Crankset:
https://bike.shimano.com/en-EU/product/component/claris-2400.html
FD - Shimano Claris Triple RD2030F Braze-on
RD - Shimano Claris 8x RD-2400-GS
Shifter - Shimano Claris R243L/R240R
Crankset - Shimano Claris 2403 Triple 50/39/30
Cassette - Shimano Alivio HG51 8-Speed (11-13-15-17-19-21-24-28t)
BB - Shimano BB-ES51 68x121

Going the whole year with this setup made me end up with not using the lowest Chainwheel '30' anymore and mainly using the gears 11-17 on the cassette. Doing so, I felt like carrying stuff for nothing and also abusing a cassette only halfway.

Therefore I took the Shimano compatibility guide (https://productinfo.shimano.com/#/) and checked what is possible by:
- Keeping a flatbar
- but still a road setup
- with a 2x XX gear
- good quality, but not directly Ultegra or Dura Ace

I ended up with looking at the Tiagra and the 105-5800 Group from Shimano.
Since the 105-5800 is quality wise excellent and only a bit more expensive than the Tiagra, I did choose the 105-5800. https://bike.shimano.com/en-EU/product/component/105-5800.html

Since I couldn't get hold of a decent priced 105 Brake lever BL-R550, I went for the 
Tiagra BL-4700
with:
105 Shift Lever SL-RS700 2x11
105 Front Derailleur FD-5800
105 Rear Derailleur RD-5800-SS (short cage)
105 Cassette CS-5800 11-speed 11-28T
105 Crankset CS-5800 52/36T, 175mm
Ultegra BB SM-BBR60

in this very moment I also decided to replace my V-Brakes with new ones:
Alivio BR-T4000

and the spd m324 pedals with new:
PD-EH500
