So without recourse to the calculator- approx 140psi?

How about the Ksyriums? (Playing chess and too lazy to Google) I presume they come under the same thing?

In which case it seems odd that they came with those tyres.

Yes, 9.5bar=140psi, near enough given the resolution and accuracy of pump gauges.

The 120psi "minimum" written on the sidewall should be taken with a large pinch of salt, usually that number refers to the lowest pressure which will safely support the maximum design load, which would be relevant to you only if you weight 20st. The maximum written on the sidewall is again only about the tyre, and you should always check the rim rating too and use the lower figure. Corima carbon clinchers, for example, have a maximum of 8bar for 23mm tyres. Stress on the rim increases with increased tyre cross section, as the casing tension rises as a function of curvature radius.
