Extensive research on this website and others persuaded me to attempt a wide ratio drivetrain on a limited budget.
I started from a mostly Shimano 2x10 mtb setup that performed well enough for me except that it lacked top end.
I replaced the existing bb and 2x crankset with Deore Hollowtech. I replaced the 38t ring with a 44t intended for 3x. I replaced the 2x front derailleur with a 3x in order to accommodate the larger delta.
Shifting the front on the stand exhibited a consistent property of wanting to drop onto a missing “middle ring.” I solved this by increasing the gap between derailleur and big ring from the recommended 3mm to 6mm. Shifting seems flawless to this old gheezer. Cross chaining no prob. Split shifting no prob.
Very good, very economical modification for graveling the Ouachita and Ozarks! 🤓
I learned that there are many more ways to do it with road oriented components.
I’m still questioning the wisdom of a gravel-oriented mountain bike, but I didn’t spend but $1200, so it was a conservative gamble.
The main thing is to get out and ride!
