Some progress. Here's an initial drawing from the builder.

I suspect I need to increase the minimum chainstay length to 425mm. I want to accommodate 700*40 with guards, and 27.5*2.25 without. My calculations suggest this should work...

Whats the maximum chainstay length? My sliders make the CS 415-435 and 435 is absolutely plenty space. You might run into trouble trying to get 2.25s in the rear though. Thats the kind of size that needs a wider bb so theres space for the CS inbetween the tyre and crank spider, even with 650b

Which bike is that on?

I'm basing my geometry on the cross check, which has a stated chainstay length of 425. Perhaps that is measured to the midpoint. I shall check.

I'm nervous about 2.25 in the rear. Might settle for 2.1 or 2.0. But if I do that I might also check the BB drop.
