Review on Schwalbe XXLight Bicycle Tube 1 5 2 35 by Andy Edwards

I used them on my 650b touring bike for a few years. They're very light, but you pay for durability and air retention. You'll need to top up the air pressure every few weeks, and if a sharp object punctures your tire, you'll have a flat tire simply because the inner tube is so thin. Heavy-wall tubing can withstand piercing through very small pieces of glass. Finally, you must be careful when mounting/dismounting tires with these inner tubes. I recently had a tire lever that slipped a bit when mounting a tire, and the plastic tire lever tore a slit in a brand new inner tube. However, these problems arise with such lightweight cameras. I will continue to buy them.
