Didn't exactly know which forum to post this in, but I figured I could get some answers in here. I'm currently building up a Jamis Parker and am considering getting an '09 4x rc3. I will use this bike for a small amount of gated racing, but mostly trail riding/ light fr. I love my 888 rc3 so the 4x looks appealing, but I am concerned about it being only 100mm. Finding minimal reviews, any input would be great.
