These tubes are compatible with ETRTO tire sizes ranging from 47-622 to 62-622.

Troubleshooting
Tube won't inflate
Ensure the Presta valve nut is unscrewed and that the pump head is securely attached. Check if the valve core is clogged or damaged.
Tube deflates quickly after inflation
Check for a puncture by listening for escaping air or submerging the inflated tube in water. Inspect the tire and rim for sharp objects or damage that may have caused the puncture. Ensure the tube was not pinched during installation.
Tube feels uneven or bunched inside the tire
Deflate the tube, remove the tire bead opposite the valve, and carefully reposition the tube to ensure it is lying flat and evenly within the tire casing before re-inflating.
