My computer had a moment while I was typing this is what I meant to say lol.
Sorry Guys/Gals, wasn't here to answer your questions, yes the silicone runs down the center of the Rav-X tape but it is pretty wide and for $12.99 it is two rolls with plenty left over for most bars as I have used it on my 46cm drop bars without running out.I have also used another Rav-X Tape that I like but can't remember the model off the top of my head, it is thick like cork but has a no slip rubber feel to it, handles vibrations very well and is really comfortable. I had it on my Jetter when I built it just to give it a try and now I am swapping the bars over to a Bianchi Europa and the tape is staying with the bars.
