Yea that's what I was thinking, Ascos are pretty affordable that's for sure.. and everyone gives good reviews on them. Post up these Black Maxes so we can check em out.
same hear i been running 4 1/2 inch black max for 5 1/2 years i took one valve apart 1 time and cleaned it but that it they aren't the fastest but the most reliable i have ever seen. I have installed just about ever kind of valve and everything else has had more promblems just my 2 cents oh yeah the black maxs are on my daily ride also so they get used everyday
