I have to say that, whether it be psychological or physical, I've consistently* found that my sub 18 lb gofast with very light wheels seems to let me turn the cranks more easily in a higher gear (75") on the same hills where the same cadence feels slower or seems to require more effort in a lower gear (67" to 70") on bikes with heavier wheels, including, oddly, the Ram with Parigi Roubaix. The tires on the have been 650C 200 gram Grand Prixs and, recently, slighly sub 200 gram 23 mm Pro Race 3s. Smooth roads.
*Consistently, ie over the almost 14 years I've owned the gofast, and measured against many different bikes. So much has this been so that, on the many, many times I've thought to convert the gofast to something more "useful" -- wider tires, rack, lights -- it takes only one more hilly ride to remind me that I love the way this bike feels on hills. (By the way, I have no desire to take this bike on dirt roads. I have three other bikes that can to varying degrees handle dirt roads.) It may well be only a "feeling", but it is a very persistent and consistent feeling.
