Hello everyone,
I too wanted to thank everyone for the many tips...
Here are the pictures of the bike, mounted with SRAM red.

Assembly went well... the main difficulties were related to my ignorance... for example, finding the front derailleur sheath stop...
I opted for integrated wiring, with CHB1036 handlebars. Patience is needed... once the sheaths were in place, some cables jammed because of the angles of the handlebars... back to work!
Next, I wanted mechanical disc brakes for weight reasons. I'm pretty happy with the result.
I must have done 600 / 700kms with the bike.
I'm very happy with the way it rides: comfortable and light!
Bike adopted!
