I'd originally assumed that I'd be going 105 Di2 for my next build, but honestly availability seems really poor in Europe at present. And good luck getting your hands on any Sram AXS. Ultegra is too pricy for me, so... back I come to the L-TWOO Erx which is looking increasingly tempting.

Being able to run it 11 or 12 speeds also allows me to use a lot of parts from my spares box that would otherwise be redundant and I can step up to 12 speed at some point in the future when things wear out.
