650c Standard Presta Valve Tube

The tube fits 27.5"/650b wheels (ISO 584) and comes in variants sized for tire widths of 1.75–2.4" or 2.3–3.0", so check your tire sidewall to match the correct model.

It uses a Presta valve only (not Schrader) with valve length variants of 32mm, 40mm, and up to 60mm; some models have a removable valve core while base models do not.

The tube is made from butyl rubber and is molded for consistent wall thickness, with each tube individually cured for quality.

Verify your tire width, valve length, and rim type before purchase because mismatches can cause poor fit or installation issues; users note occasional pump snugness and have addressed minor valve leaks by tightening the valve lock nut.
