Replace drive train on Giant Reign x1

[mhbarber]

I commutted for years and the whole drive train is knackered
As it's around 2007 vintage, I'm unsure what to replace the SRAM components with, its a mix of X7 and X9.
I'm going to change the brakes too.
There's so many pitfalls with drive trains. Braze on. English threads. BB types . Number of bolts.
Nightmare.
I'm brand agnostic.
I am happy with 105 levels of performance.
Words of wisdom appreciated with regards buying replacements and fitting. I have a reasonably extensive bicycle toolkit

What are you aiming to achieve? The Reign is an "All Mountain"/borderline downhill bike, you're going to strike fairly substantial issues trying to fit road gear, particularly around the crank area.

If you want 105 levels of performance, you need to use SLX MTB gear.

I made my 2009 Reign 1 into 1x10. Narrow wide ring, 10 speed SLX shifter, 10sp SLX clutch derailluer and XT 10sp chain.
