Tube 700x20/25 27x1 to 1-1/8

Inner Tube, 622-630 mm x 23 mm thru 25 mm width.

This 23 mm -25 mm tube size fits 622 mm rims and 700c x 23-25mm tires as well as 630 mm rims and 27" x 1-1/8" and narrower tires.

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.

Separation of Presta valve stem

    I kept the tires inflated a 100 lbs. After two months both tubes developed a separation at the seem where the presta valve is attached and in the same week. I checked the rim tape. Next time I'll deflate the tubes every day and see if they last longer.
