About this part

The Macfox inner tube is a rubber spare tube sized to match the bike, sold in three part numbers: X1S/X2, X7/X7L, and M16. A flat on a fat tire is not the kind of thing to borrow at the roadside, so keeping the correct spare on hand is worth it before a long ride.

Keep tire pressure inside its recommended range, since most fat-tire flats on these bikes are pinch flats caused by running the tire too soft. Select the part number that matches the bike before ordering, since the three sizes are not interchangeable between models.
