Continental bicycle tubes are constructed of durable, seamless butyl rubber and are 100% inspected to ensure high quality and reliability. Seamless, and vulcanized to ensure uniform roundness and improved reliability at the valve stem. Every tube passes a stringent 100% quality control inspection. For 29" mtb rims, 29 x 1.75-2.5" Presta and Schrader valves have removable cores.

Highly recommended; Schrader valve with lock nut is invaluable
One of the few inner tubes with Schrader valve that has a lock nut (also called lock ring) that secures the fully threaded valve stem to the rim. This feature makes it easy to attach an air chuck to the valve stem without the valve stem disappearing into the rim/tire. Schwalbe is the other brand with this feature. Normally Presta valves come with a lock nut but Schrader valves do not.Went on very easily on our kids 20" BMX bike with 57-406 tires. Works well so far. Seems to be made of thick rubber and manufactured with minimal/no seams per Continental's unitube process.

Good tube for BMX tires
Very good tube with retainer screw for schraeder valve. Do not buy 1.9-2.2 wide tube for BMX, it will blow.Buy this one.

It’s the little things
Love the all metal stem and the small ring fastener that keeps the valve stem tight to the rim making a low tire super easy to fill. Will look for this feature on all tube purchases because of how convenient it is!!

Replacement tyre tube
Happy with this item, it has a lock nut to keep the valve from depressing into a flat tyre when attaching the pump .

buone
uso già quelle da 27.5 e mi trovo bene sono spesse e resistenti.queste sono solo più piccole ma sembrano avere la stessa resistenza.più avanti cambieremo anche il copertone.quelli di decathlon sono raccapriccianti,si bucano con una piccola spina di rosa
