My Rivendell road bike- the Rambouillet- is about the same weight as the Jamis.
My bike is lighter than lots of hybrids are, heavier than carbon and aluminum bikes. It feels great to ME. (Note: often on websites, they will quote the FRAME weight...WITHOUT the wheels, saddle, pedals, etc. This Jamis quote is for the whole bike. Don't confuse frame weight with whole bike weight when comparing).
