In January 2012 I was in need of a new bike. After deciding that I really couldn't afford what I thought I really wanted I bought a leftover 2010 650b1. I ended up being very happy with the bike untill Friday. About a month ago I landed a trail jump a little hard and heard a pop. I checked things out and found nothing so I laid it off on chain slap. Friday I was riding and hit a small jump that I landed smoothly and I heard the noise again, but this time it was obvious what it was. The bolts at the top of the linkage had sheared off. I couldn't find a number for Jamis so I filled out the Email form on the website. Hopefully it will all be resolved in a few days. Has this happened to anyone else?
