I was at the LBS the other day to find the local trails and the cobia caught my eye. From where I used to ride the liquid was great but the the cross country stuff here the 29er may be the way to go. Couple questions....What is the differance between the alpha platinum frame and the alpha gold frame? How is the rock shock reba? It seems many bike mfgrs now make their frames overseas, what gives? I like the X-caliber but the red on the cobia is awsome looking in person. I found a bike shop that does consighnment.
