It looks like the Oryx is a touring 'bent with dual-26" wheels. Compared to their competitors, Optima tends to be on the heavy side, and adding suspension sure doesn't make it any lighter; but what the heck for the right price it'd be a nice ride, if somewhat slow on climbs. It's just me, but I would not want an older 6061 alloy frame, which were not only a softer alloy but weren't even heat-treated. The new 7005-series frames are something like 3 times as strong.
