To the 2by lovers: be aware that fitting 50mm wide tires (29x2.0) will cause problems with a front derailleur. In my case a eds tx front derailleur and race kings in 29x2.0 on elite wheels aero + rims with 30mm internal width. It just can't work because of the interference.
Even specialized pathfinder pros in 44c won't work on these rims as they build up to 46mm.
I'm pretty sad, as I bought the frame for riding 50mils with a 2by crankset.
