So I went ahead and did the thing, so here's my MTB frame with non-adjusted gravel forks.
predictably, BB drop is going to be my enemy, but I think with big tyres it will be ok?
Currently with these wheels I had with ±25c tyres the drop is 235, which is danger zone
I have calculated it would be 262 with the 2.1" 29er tyres I wanted to put on it, so if I have a 165mm crank that seems pretty safe, but I am wondering for smooth road riding (or where I am not expecting #nogravel), whether I can get away with 35c? And is 165 really necessary, or can I get away with the BB30 cranks I already have that are 172.5? Maybe I can trade down...
Also, is baby-blue gravel the new baby-blue fixie? (I might have to paint the frame to match the forks ;P )
