The spec Ritcheys (which I have, but just felt that these amberwall DGs were so much cooler) are 1.9s, so I guess they would weigh less than then 2.1 DGs. So I probably could drop the weight even more, just don't like the look of an Adroit with such skinny tires. I have a pair of amberwall 2.35s but they were really dry in a couple spots. So, not even good enough for display really.
