## Questions & Answers

**Q: Can I put these into tubeless tyres?**
A: Yes they can be used in tubeless tyres if you wish to use a tube

**Q: Are these inner tubes suitable for 700 x 20/ 28**
A: 28 yes, range covered 25-32.
I'd say too big for 20.

**Q: The photos show a schrader valve not a presta valve. Can you clarify the valve type and length?**
A: The inner tube is available in both valve options with the Presta being a standard 45mm valve though 60mm and 80 mm options are available in presta.Steve

**Q: Is the inner core removable and how do I specify the length of the presta valve (a previous answer says there are options)?**
A: I think the core is removable.  The presta valve needs to clear the rim by approx.  30mm so you can connect the pump on.  If you have a pump with the flexi end that screws on, this is not as critical.  You need a longer valve if you have wheels with an more aero design.  60mm should cover most applications.  Should you have to use the new tube, you can measure the length of the old valve!

### ⭐⭐⭐⭐⭐ Great buy
*by D***Y on 8 July 2026*

Really pleased with these tubes. And the price

### ⭐⭐⭐⭐ Good value for money but nozzle can be a problem
*by T***D on 27 November 2025*

I have ordered a few of these and they seem to be of adequate quality but the nozzle can often become faulty and let out air. Quality control isn't great on these but for the money, I think they are good value.
