I think I have landed on something I'll be riding for a while... the Pelso Brevet. 700c with HUGE tire capacity (running a tapered headset Whisky No. 7 full carbon with hydraulic disc front brake, mechanical disc in rear). The ride is very compliant, smooth, power-efficient. I get about the same exact boom flex as the Bacchetta CA2.0. The components are SRAM mechanical 10 speed, triple up front with 11-40 in rear. I can climb anything. The J-bar setup is very ergonomic, though a bit more flexible that I would like. Also, mounting a computer is tough if you didn't get one of the custom mounts before they stopped being made at CCFineCut (https://www.ccfinecut.com/garmin). I have a setup on my commuter (also have J-bars on it), for the computer, but it's not quite as elegant or adjustable.
My only gripes about the Pelso: 1. chain line and fork... it slaps the top of the fork if you hit heavy bumps (had to put some gorilla tape where it was hitting), 2. the light mount is total crap (why couldn't they make something that actually fits with existing light mounts and actually mounts fully rigid? The adapter they sell wobbles if you put any legit light out on it), and since the derailleur hanger is custom; there's no way to mount a light out front (like the one-arm bandit)., 3. the headset cups should have been made of aluminum.
Everything else... is what I would ask of the Bacchetta or Schlitter models to become... I can handle 2" tires on this rig if I wanted. It has rack mounts! YES!. It has recessed cable routing (SO CLEAN). It's light, fast, nimble, and rides on my local rural chip-seal roads... like butter. I'll update in 10K miles.
