Whether the Maxxis Aspen ST fits your bike is decided by one number: the bead seat diameter, the second half of an ETRTO size. This tire is made for 686 mm and 622 mm rims — 32-inch wheels and 700C / 28-inch / 29-inch wheels. If your rim matches, the only remaining question is width, and that is a matter of frame and fork clearance rather than of fit.

7 listings across 5 sizes. Where a size appears more than once, those are genuinely different products — a different casing, colour or claimed weight. The “printed as” column is Maxxis's own marking for that size, which is what you will find on the sidewall and in most shop listings.
