This covers most 28-inch road, trekking, and city bike tyres with widths between 28 mm and 47 mm.What valve type does this tube use?It uses a Presta valve (SV – Sclaverand) with a 50 mm stem length. Presta valves are standard on road and performance bikes and require a Presta-compatible pump head or an adapter for Schrader pumps.Is butyl better than latex for inner tubes?Butyl tubes offer superior air retention — you'll need to top up pressure far less frequently than with latex. They are also more durable and puncture-resistant for everyday riding. Latex tubes are lighter and more supple but require more maintenance. For commuting and general use, butyl is the preferred choice.How do I know if this tube fits my bike?Check the sidewall of your tyre for the ETRTO marking (e.g. 37-622 or 40-622). If the second number is 622 or 635, and the first number is between 28 and 47, this tube is compatible. When in doubt, a wider tube is generally better than one that's too narrow.Can I use this tube on a bike with rim brakes?Yes. The tube itself is brake-system agnostic. Just ensure your tyre and rim are compatible with your brake type.How do I install the Schwalbe Tube No. 17?1. Remove the wheel and deflate the tyre completely. 2. Use tyre levers to unseat one bead of the tyre. 3. Remove the old tube. 4. Lightly inflate the new tube to give it shape. 5. Insert the valve through the rim hole, then tuck the tube inside the tyre. 6. Reseat the tyre bead by hand (avoid levers if possible). 7. Inflate to the recommended pressure printed on your tyre sidewall.What is the recommended inflation pressure?Inflation pressure depends on your tyre, not the tube. Check the minimum and maximum PSI/bar printed on your tyre sidewall and inflate within that range. For 28–32 mm tyres, typical pressures are 5–7 bar (70–100 PSI); for 40–47 mm tyres, 3.5–5 bar (50–70 PSI).Is this tube sold individually or in a pack?This listing is for one (1) tube. Trade packaging is available in cartons of 25 units (VE: 25).What is the difference between Schwalbe Tube No. 17 and No. 17 AP (Air Plus)?The standard No. 17 uses conventional butyl rubber. The Air Plus (AP) variant uses a thicker butyl compound for enhanced puncture resistance and longer air retention — ideal for riders who want extra peace of mind on longer tours or in urban environments with road debris.
