Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like : "Unbound Gravel".

Switch wheels to shrink tire size?

For adventure riding on my Domane, I am currently running 40mm Bontrager GR1 tires on Paradigm Elite 25 (25mm inner rim width) wheels. The clearance is decent, everywhere except the front derailleur, a Dura Ace di2, where it is very tight. My road wheels are carbon Aeolus 3s, with an inner rim width of 19.5.

Does anyone know how much room I will get by dropping down to the narrower rim?

This is a short term problem. I am waiting on a Checkpoint frame for a pure gravel build using GRX components.

Maybe i am missing something - can't you just put the GR1 tire on the Aeolus wheel and find your answer.

I could but both sets of wheels are running tubeless (which I am not self sufficient on yet and means a trip to the shop) and I didn't want to upset the applecart without some sense of benefit.
