This is a stuff from my basement build.
suntour mech with a t.a. crank and homebrew 7 speed cassette.
12,14,16,18,21,28,36 to 26,40 crank.
Works for my needs and no hill is off limits. I used belleville v.o. bars but i prefer the porteurs. May change eventually. Also i have a set of paselas on order. Life is too short to ride crappy tires.
