The builder sent me some progress shots of my new bike yesterday. Currently waiting on a last minute change in the front brake choice and should be finished Monday.
back to front. I'm going with the new wireless SRAM X range.
I don't have anything with this much range other than my 1x fat bike.
rear brake on the beefy rear end of the stick. No triangle so the end of the stick has to handle all of the force to the wheel.
front of the drive train. Yes the chainrings are farther apart than SRAM prefers for the X range
super simple controls - a thumb blip on each side to change gears. I'm not entirely sure if it is where I like my hands yet.
