I ran an Ikon 2.35 in the front and a 2.2 in the back for a bit.  Worked great on both gravel roads and single track.  Now running Ikon 2.2s both front and back.   Fast tire.

Carbon_Dude is right.  Hydraulic lines that comes with the brakes is more than sufficient if you buy hydraulic brakes, i.e., shimano.   I think Avid mechanical brakes like BB5s and BB7s come with housing also....not sure but not enough to run full length to the rear.    I bought 10 meters of Shimano SP41 housing for the shifter.  I run a 1x10 setup.  Let's just say that I have enough housing to do another 20 bikes.....way too much but I do have three other bikes to work on so no problem.  The shifter cable runs internally for the most part.  No housing inside the frame.  You will only need a few feet.....a short length for the top and even a smaller one in the bottom.... Lastly, depending on the shifter you buy, it might come with housing already so no need to buy anything additional.

1) BSA....easiest to remove and clean.  Better seal, in my opinion, than press fit
2) I used the "no bleed method".  Housing fed easily from the rear. 
3) I think there is a sleeve inside the frame.  Housing from lever to top of frame, then bare cable, and housing from rear to derailleur.....no issues

Definitely can handle a lot more....there just isn't much down here to challenge....

66 mile Everglades ride completed successfully on the CS-057.  No issues.  Nice and fast ride.

Thanks!

My main trail bike is FS Trek but this one will definitely get a few trips for sure.  As a matter of fact, I'm doing a 62 mile Everglades ride event next Sunday with it.  Looking forward to it. 

Just finished my CS-057 build. Long time lurker.  Gathered tons of info from the site.  Incredible bike.  Intended to be a levee rider.  Mostly gravel roads.  Went on a 26 mile test ride last evening.  Surprisingly smooth, fast, and felt very plush.  Not a harsh ride at all.  Dealing with Peter was great.  The 1x10 XT drive train came off my FS Trek Fuel EX8 which received 1x11 XT upgrade.  Saddle came off the parts bin.  Build list:
