BBB Schrader Tube 33mm
Reliable butyl tubes with a 33mm Schrader valve — covering smaller wheel sizes from 12½" kids' bikes up to 26" mountain and city wheels.
The BBB Schrader Tube 33mm covers the smaller end of the wheel size spectrum — from 12½" and 16" kids' bikes up through 20" and 26" MTB and city wheels. Butyl rubber construction holds air reliably for everyday riding. The 33mm Schrader valve suits standard-depth rims and is compatible with automotive pumps and most floor pumps without an adaptor. At $12.99 it's the most affordable tube in the BBB lineup.
Highlights
Covers kids' bikes to adult 26" wheels
The 33mm range spans 12½", 16", 20", and 26" wheel sizes — making it the go-to tube for smaller bikes, kids' bikes, and standard 26" MTB or city wheels with shallow rims.
Schrader valve — pumps up anywhere
Compatible with automotive pumps, gas station air hoses, and virtually all floor pumps. No adaptor needed — ideal for riders who want simplicity at roadside or trailside fixes.
Butyl rubber — reliable everyday choice
Butyl holds air longer than latex and resists puncture permeation well — a dependable, low-maintenance option for commuting, school runs, and general riding.
