Inner Tube, 29er, 700c x 50 mm thru 56 mm width.
This tube fits 29 x 1.9 thru 2.10 tires. Also fits tires marked 700C x 50 mm - 56 mm.
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.
