I have a brand new bike. I ride very very aggresive so it is an important improvement for me. If you ever get a chance to ride a bike with a full Ohlin's setup front and rear that's setup right you'll understand why I want them
If He puts Traxxion Dynamics AK20s in front, and a pensk tripple clicker in rear. You shouuld be about to do 3-8 seconds of track record.... well, thats if you are good.
