So im looking at building a bike mainly for durability for carrying heavy loads (f/r panniers, trailer and loaded 72hr pack) for going on biking trips. I dont care about weight or looks or "ooo thats some smooth shifting" i want stuff that will last many many thousands of miles with care.
So far Im looking at a surly cross check frame with the LHT front fork, shimano deore xt m770 9sp cassette, shimano saint rear der, and campagnolo athena ergo shifters.
I dont need a 3 chainring set, Id rather only have a single chainring but with my recent knee injury id feel more comfortable in the long run with having a double chainring like a 38/48 (i never leave the 48t on my road bike and hardly use the lowest ring on the cassette unless im going up the really big bridges over the intercoastal with a headwind).
Any suggestions on stronger parts than ive listed and alost on parts i havent listed. Im still looking at what front chainring set, crank and front der that would be best.
Oh and im 6'3" 257lb (but im still dropping weight! lol)
