 The stem and chain seem a little out of place, other than that, beauty of a build!
  • 00
 I think im gonna get the xtrs now, did they size right with that frame?
  • 00
 They fit perfectly with one 2.5mm BB spacer on each side and two 1mm axle spacers. That got me the perfect 43mm Chainline.

 How come you are running XTR's versus something like Saints or DXR's?
  • 00
 Well I got these XTR's for insanely cheap! They are 170mm, which lowers the chance of flex and with the shorter cranks I am running a slightly easier gear (40/15). Saints are stiff as heck, but make for a terrible chain line(I tried them).

I was afraid these cranks might be flexy as heck but they are incredibly stiff! The BB of the frame deflects before the cranks flex. I'm very happy with this set-up at the moment but time will tell if it was a good choice.
