Are the dropouts in the drawing what you need? I have a set of those low IS mount QR paragon things I got as part of a lot from Carl when he was clearing out stuff. No plans to use them any time soon.
I just finished another fast bike for fat tires but this time in my size. Designed primarily for 650x47-50 or 700 x 33-38 with comfortable clearances. Fork will be the new whisky flat mount CX. DI2 internal with modular external routing for rear brake/derper on the downtube. Kinda porky at 2000g raw tho. Just dropped it off at the powder coaters to get it done in Grape Forest Splash Chameleon.
Some frustrating issues tigging in the tight spaces around the chainstays, under DT and between the ST/DT. Under different circumstances I probably would’ve scrapped it but I wanted to have something new to ride at Grinduro
I also think once I use the remaining set of these flat mount dropouts I have I’m going to move to the paragon Syntace system and do brake mounts seperately. It’s a real PITA to get these things straight, although the brake mount part is super easy.
