Can you get the Marathon Supreme? I hear it rides lighter than it is. If not, get the Continental.

For arcane reasons, it's not correct to call this size 27x1.25, even though it is the same numerically as 27x1-1/4. Some bike tires are expressed in decimals and others in fractions. Switching between them implies a different size. The only accurate sizing system is ISO, formerly known as ETRTO. The ISO spec for your size is 630x32, because that is an actual measurement in millimeters.
