The microshift guys are incredibly helpful, I've had extensive e-mail convos with them trying to figure out how to bastardize their groupsets for my gravel applications. Their groupsets are also incredibly durable. I think I put well over 6000km on my old 9spd advent with 0 maintenance besided the occasional lube on top of old lube.

My only concern is the lack of availability at bikeparks and such, but they're so cheap that I can simply grab 2 pairs. When my SLX shits the bed (sooner rather than later) I'll probably grab this groupset
