Fuji Altamira 1.1 2016 (their website reports 20.44lbs stock)

Upgrades RS81 wheels, 105 pedals, Oval 900 carbon wrap seatpost, Specialized Romin saddle, lights, SRAM Garmin mount, Garmin sensors, two water bottle holders, 20.0lbs even as per Park Tools scale (includes everything).

It fits right and is the fastest rig (judging by all my PRs on Strava) that I've owned, despite its weight.
