Im considering updating and upgrading my 2016 canyon cf slx, and have some general questions about my options ...

My goals from a new bike are a bit of a mix between the practical and what I think would be cool ie I am interested in the performance of the bike, but have non-performance interests that are at least as import to me, a true middle pack age grouper who would like to try to get a little faster than i am currently.

Ride wise i am after
-> disc brakes, so that i can share wheels (at least training wheels) with my other bike
-> 1x, mainly because
* it looks cool
* i have a track background and still enjoy riding a bigger chainring than everyone else
* like having less mechanical parts for travel, maintenance etc
-> integrated front end with no exposed cabling
-> uci legal options, since i would like to go back to riding some uci tt's

I would be happy buying a frameset and building with parts, or possibly complete if i can find the right bike. my budget is probably ~$7k USD although i'm a bit flexible. i do really like more interesting/niche brand options, like tred, or less niche but smaller brands like wilier etc. I am a bit of a snowflake I quite like having things that are a little unique. I don't exactly know what the price points of going this route though ...

So i would be really interested in everyone's thoughts and opinion re options here. in particular :
-> what is the 1x landscape right now? what setups would be a best option in terms of price, ease of installation, servicing, etc
-> dumb question about front ends ... aside from looking carefully at pictures, what exactly determines the cabling here? my current setup is an absolute birds nest. why do some bikes, eg orbea ordu, or p5, look completely clean ... i cannot see a single cable ... if i were to build up my bike from individual parts, what do i need to be careful of to make sure that i can achieve that too? thats probably a stupid question ...

thanks ! looking forward to hearing your opinions / advice. much appreciated!
