I spoke with the BMC rep in Austin the other day and asked about a 29'er. It looks like they have a rigid as well as a FS 29'er for 2012. That was all he would tell me. I would expect to see the first version late this year or early in 2012. Should be interesting, if the 29'er is as good as my Fourstroke 02, I am in!
The word I've received from reliable sources is that they're 29ers are done! They're in the process of privately demoing them to a few shops. They should be unveiling, and possibly launching, them very soon ((Sea Otter maybe??))
