i have an SST AL as well, just a couple months old, and it does the same thing. Ive taken off the crankset, greased it, torqued it tight, and still have the same problem... just a ****ty BB to be honest.
And i have 2 BD bikes, had a small missing dropout screw on the SST that they fixed for me right away. On my mtb, BD even sent me a replacement fork with very little questions asked.
