Whether the WTB Riddler fits your bike is decided by one number: the bead seat diameter, the second half of an ETRTO size. This tire is made for 622 mm and 584 mm rims — 700C / 28-inch / 29-inch wheels and 650B / 27.5-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.

All 10 listings
10 listings across 4 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 WTB's own marking for that size, which is what you will find on the sidewall and in most shop listings.

How the WTB Riddler compares on weight
Each row weighs the lightest listed WTB Riddler in that size against the lightest listing of every other model available in the same size. Models are compared once regardless of how many colours they come in, and tires with no published weight are left out of the ranking entirely.

|---|---|---|---|
| 37-622 | 465 g | 698 g | 2nd lightest of 30 |
| 44-622 | 541 g | 541 g | 3rd lightest of 5 |
| 54-622 | 840 g | 725 g | 11th lightest of 15 |
| 57-584 | 1108 g | 735 g | 12th lightest of 13 |
