Maxxis Tube 20 x 1-1/4 x 1-3/8 Welterweight FV 48mm RVC 0.8mm

Reliable tube for 20" youth and utility bikes. The Maxxis Welterweight 20 x 1-1/4 x 1-3/8 fits narrower 20" tyres common on kids' bikes and entry-level BMX. The 0.8mm wall gives a sensible balance of weight and puncture resistance. The 48mm Presta valve with removable core suits performance rims. Check your rim drilling before fitting — this valve won't work in Schrader-drilled rims.
