Hi folks,

Have a large 2012 El Mar steel frame, and I'm slowly accumulating parts for it. After considering various cranks, I'm going for a 3x10 XT this time around. As for a derailleur: the cable routing will come from below the BB on this one, but I'm not sure on top or bottom swing. I don't have the crank, but I'm hoping to order the fr derailleur at the same time. Will probably be XT as well. Now the answer may be obvious, but this is my first "new" mountain bike in 20 years, so bear with me.
