20", 451

$4.99 - $7.48
20" 451 tubes. Okay, what is a 451 anyway. It's a 20" tire/wheel size used mostly for a lightweight BMX racing wheel. The rim is about 1 1/2" taller than the more recumbent popular 406. It's vital when selecting tubes that you pick 451 when you need 451. You can usually tell by the size printed on the sidewall. Except in a couple of cases, 451 tubes end in a whole single digit or fraction (20 x 1, 1 1/8, or 1 3/8). 406 on the other hand ends in a decimal ( 20 x 1.25, 1.5, 1.75). The odd balls are Schwalbe Stelvio and Conti Gran Prix. The Conti 406 is labeled as a 20 x 1 1/8, the Stelvio 406 and 451 are both labeled with 20 x 1 1/8! Choose wisely! We also have 451 tubes available with a 60mm presta valve for those deep rims.
