Minor update, because I'm bored and receiving parts is the most exciting thing during the build process.
BB & headset arrived last week, installed very easily.
Forks are not far off, went for new Lyriks, 160/130mm dual position, once they arrive I can start playing with stem length and bar setup as I have wheels & old seat post that will fit, and I already owned the XX1 groupo before starting the build, so I can pedal around brakeless! Yay!
Also bought a OneUp chainguide, these things are sick, I've been waiting for it to be available since the press release
Lastly for this post, considering an Absolute Black oval chainring, will be setting my dads Turner Czar up with one (& XT 1x11) soon to try before I buy, anyones experience with these would be greatly appreciated
