+1 for the 1x, very happy with my 38t chainring and that SRAM cassette. Spins out about 35mph but I shouldn't be overtaking cars on a descent like a mad bastard while loaded with crap anyway :) If you get the whole group it comes with a 42t on the front. I didn't have any issues with gaps in the range on a hilly two day trip recently (compared to my other bike with a 11-32t 10sp rear).

I made a little chrome browser extension to put google streetview images next to the map on trackleaders.com: https://chrome.google.com/webstore/detail/trackleaderscom-streetvie/bbmkgjigigfdfoofbngfagmpadgofakl
Estimates the heading from last two points so will go a bit random on very windy roads or for riders that don't update often cough but you can click it to open full version.
(it will now, inevitably, fail to work for anyone but myself)

Apologies if repost.. this blog post from (renowned vendor of wide tires) Compass showed up in my feed today, quite interesting:
https://janheine.wordpress.com/2017/05/29/the-trouble-with-road-tubeless/
tl;dr: tubeless no good at high pressure so go wide or go tubed.
I'm a bit skeptical, but then I run relatively low pressure anyway. Not too worried.

170 grams for a bit of insurance.
I'm the worrying sort so that'd be a no brainer - if it's pissing down I want to change the tube and get moving again ASAP. Also, I guess not so relevant since you're self-supported anyway but there can be very long stretches with no cellphone coverage. This is a big mostly empty country. Edit: tyre != tube, duh :|

I have an Apex-1 group and the stock chainring appears to have some inboard offset now that I look at pics, however I replaced the stock ring with a race face 38t that doesn't appear to have any offset and it runs fine in the same outside position. Maybe the cranks have some compensation offset.. SRAM don't specify.
