I've been experiencing hand pain and numbness that has continued to increase over the years. Ergon grip help, but I'm not thrilled with their shape so I have decided to try some Alt Bars. For those of you who are unfamiliar with the term Alt Bars, let me explain. Traditional MTB bars fall into either flat or riser bars. Both of them are pretty strait forward, offering multiple rises and widths. However they all have one thing in common, they use sweep (how much they bend back from strait) of 3 degrees to about 9 degrees. Alt Bars buck this trend by offering much greater amounts of sweep, up to 45 degrees. To offset the amount of sweep (which puts your hands closer to you) you either need to use a longer stem or the bars will have forward sweep prior to the back sweep. I chose to get the Origin 8 Space Bar OR, which has a 37 degree back sweep but also has forward sweep. They feel funny BUT no hand pain with standard grips...none! I'm sure I'll get used to them.
