Schwalbe SV15 700C Inner Tube

Excellent and have lasted a few months now.

So far, so good! The quality is evident right from the start, with the tube coming in a beautifully designed box that instills confidence. It fits my 700C wheels perfectly. Great value for a high-quality product - highly recommended!

This is a mid-priced inner tube for road/racing cycle tyres 700mm in diameter and with a skinny profile for minimum rolling resistance and higher speeds. The tube is fitted with a Presta valve which will allow tube inflation to >100psi pressure, and the design makes over-inflation impossible. The tube is synthetic rubber rather than natural latex and claimed by the manufacturer to be "...extremely airtight! The butyl rubber compound prevents pressure loss and fewer occasions to inflate". Weight of the tube is a modest 104g so no problem to carry as a spare in your saddle bag. The only caution is that the design of Presta valves means they can be rather delicate and occasionally break, necessitating the inconvenience of a tube-change - so always handle carefully and use the screw-on dust cap to protect them.

Excellent quality tube

Bought for a fixed gear bike. I needed the longer prestas to fit deep rimmed wheels. These do the job perfectly! Well made - easy enough to fit - no weak points at all on mine - pumped to 80psi with no issues. Been on these for over a month now with no problem. I pump mine up every few days but that's my personal preference. Great innertubes! Good to go!

I've bought these as spares and have yet to actively use, however as some people report leakage on delivery I checked the three I purchased on arrival and can confirm they are leak free and look reasonably robustly made - I don't anticipate issues with valves from what I've seen. I've yet to test them up to pressure as have not had them in a tyre. I use spares to swap in a new tube if I get a puncture and then mend my punctures at leisure. I generally find that if I use decent quality tyres and run at 90+ psi I rarely get punctures, so am not sure how soon I might be able to report on their functionality in the field.

The ones I bought had a slow puncture on the metallic valve which could not be repaired. Despite one of my inner tubes being faulty, the quality of the rubber is decent and the price is/was reasonable. The product was also dispatched/delivered promptly.

The right product at the right time - brilliant

Wie immer und auch erwartet. Gute Qualität zum angemessenen. Ich kaufe seit Jahren nur Schwalbe Erzeugnisse und habe noch nie Probleme gehabt.

Producto de buena calidad y muy versátil en distintas medidas de cubiertas.

Deze fiets banden waardeloos ze zijn al lek als ze uit de verpakking komen slechte koop ooit .Alle 4de banden binnen 2dagen lek gr berg

Pas de crevaison jusqu'ici. Montage facile. 14 mots minimum manquants. C'est une bonne chambre à air. L'air que j'ai pompé dedans à l'aide de ma pompe à air est resté dans la chambre à air. C'est exactement ce que je souhaitais que cette chambre à air fasse: garder l'air que je lui pompais. Donc c'est bien.

Guter, haltbarer Schlauch, der den Luftdruck lange hält.
