    Attention Mechmann Mtb.

    Hey I just got one of those 30t 140mmBCD extralite chainrings we were talking about on the 29'er board. I have installed the ring to run 1x9, but I am having a problem w/ the chain jumping. It is almost like it wants to fit the spacing of an 8 speed chain. It said on the paper check for chain fit etc. Just wondering if you can help me solve this skip problem. It is not bent, it just seems it doesn't want to let the chain fall into place etc. Thanks in advance. JC

    Nevermind my man. I found on the sheet the ring came with that I needed to file the spider of my crank down 2mm in a 45 degree angle, I did that and it works great. Thanks, JC
