I'm kind of locking in on the carbon GRX 600 versions of Warbird with 650b, Cutthroat, or Diamondback Haanjo EXP as my main options based on tire size and gearing. The Diamondback is in the mix because of the 21 in. stock low gear but the mechanical brakes are a negative. I'd like to wind up around 20 gear inch ideally but with the GRX 810 RD on both Warbird and Cutthroat I don't think I can get much below 24. Any comments on people that have gotten lower would be appreciated!
I don't know if something like a Wolftooth Roadlink was used but I did see something about a 46/30 crank and 11/40 cassette working on the Warbird. If so that would get me to a 20 GI.

Can you order the Warbird from a retailer like REI with 650b as a delivered option? I'm wondering how much they would be willing to swap out and avoid purchasing a second set of wheels.
