What to Compare Before Buying
Check the size printed on the tire against the tube’s 27.5-inch diameter and 1.75 to 2.5-inch width range. The ETRTO range, 47-584 to 62-584, provides another size reference.
Confirm that your rim uses a Presta valve and that a 42 mm valve is suitable for it. This pack contains two tubes, which can cover two replacements or leave one available as a spare.
Before You Decide
Match the tire size, verify the Presta valve type and length for your rim, and confirm that a two-tube pack fits your needs.
