Any monkies got pedal time on the new(ish) carbon XO cranks? I'm running Saint M810s 1x9 on my AM bike and am looking for some weight loss measures. I dont huck it to flat and my quads are rediculously atrophied from a general lack of quality training so 'flex' aint an issue. I dont have an afiliation to either SRAM or Shimano either way and have had good experiences in the past with both.
