Schwalbe AV4 Tube Schrader (450 x 35A) - 16 x 1 1/8-1.35 Inches by Schwalbe

My wife rides her Gekko trike and her StreetStrider daily. These have 16 and 20 inch tires that get heavy wear and need protection from goat thorns. For this size, Schwalbe tires are my first choice and with them, I buy Schwalbe tubes. They have never let us down. Are a little more expensive, but the performance is worth it. Strongly recommend.

This review is for Schwalbe AV4 Tube Schrader (450 x 35A) - 16 x 1 1/8-1.35 Inches by Schwalbe.I have never had inner tubes with a metal threaded valve stem before. This idea is genius! there is a little ring that you screw down the threads of the valve stem that keeps the valve stem from pushing back inside the rim when you try to attach a pump to the inner tube! It makes filling your tires so much easier! why don't all inner tubes have stems like this? I'm never going back to the old rubber valve stems now that I have tried these ones!

Perfect for the tires on my Brompton. Great quality

Went on the Brompton nice and easy. Good value too.

Great tube

theu are great inner tube for brompton P line

This is the tube you want if you ride a Brompton Folding bike. Other 16" tubes I tried could not tolerate the100 lb pressure needed for the Brompton's tires.

Great inner tubes. Quality valve with threaded stem and retaining nut, which fits my Brompton rims perfectly (many others are slightly too large). Best inner tube I have found. Will be buying more of these...
