Inner Tube, 622-630 mm x 35 mm thru 45 mm width.
This 35 mm - 45 mm tube size fits 622 mm rims with 700c x 35 mm - 43 mm tires as well as 630 mm rims with 27" x 1-3/8" tires.
This size is also sometimes marked: 28 x 1 5/8 x 1 3/8
Since tubes are stretchy, they do not need to exactly match the size of the tire. Depending on stock, size shipped may not be exactly the same as listed in the pull-down menu.
Make sure you specify valve type:
Schrader valves are the same as used on automobiles.
Presta or "French" valves are narrower, require a different pump head. Available in 32mm or 48mm length.
