[quote]You can run tubs at higher pressure for low rolling resistance.
Until recently, conventional wisdom held that the higher pressures possible with tubulars gave them a rolling resistance advantage, but there now appears to be mounting evidence that tubs actually suffer higher rolling resistance than clinchers due to hysteresis losses in the glue used to attach the tyre to the rim:

Certainly, the above articles were enough for me to hold off on buying tubulars for the time being.
