I know dude! I use to always do x-ups but with my new wider bars is very difficult. Wide bars are cool but suck for other reasons, hahahha RideOn great style mate!
I have a very bad shoulder and cant reach my right arm back.
I too want to cut my bars from 780mm to maybe 750-760mm But still its to long for x-ups. Its funny how just longer bars make it impossible. RideOn mate!
I had 8 dislocations last year through 2010. I have been rehabilitating and exercising for the last 8 months and I feel much better but, My shoulder is very loose and feels like it will pop out anytime.
SO, suicide no handers would really put tons of stress on the shoulder cuff! But, its all good mate!
Please have fun riding and trying new tricks! RideOn!
