what would happen to the ride of my bike if i bought new stem and bars??  The only reason i am asking is that i like the ride of my bike but new stem and bars are in order   At The Moment i run the standard 07 onza t-pro bars and stem on a standard t-pro BUT  i am going to buy new bars and stem and wondering how much of an effect would a echo team stem and either GU flat bars or echo low rise will effect the ride?  thanks  Jack.
