2 Pack Bike Inner Tubes - 48MM Schrader Valve & 80MM Presta Valve - Butyl Rubber Replacement for Mountain & Road Bicycles - Durable & Puncture-Resistant for Commuting, Racing & Off-Road Adventures

Best value out there. I paid $6 for 2 tubes. Yes, the shipping may be a little longer than some others, but for $3 per tube, if you are not in a rush, it's worth the wait. The tube fit perfectly and is exactly as described. If you have a standard valve, this tube will still work. Cheaper than any other tubes. Since I just got these for my son and wife's leasurly bikes, perfect...Good quality, great price and the right stem length for my wheels!Easy to install and no flat gets. The longer valve is easier to use.Awesome product, perfectly fit on my 26" bike (male)Great quality and perfect valve length. Couldnt find any other tubes that had a stem long enough to be easily accessible on my mountain bike until now.I cut up my old tubes bc the spokes were causing me to get flats. So I laid a 1 inch strip over where the spokes poke thrubefore inserting my new inner tube. inflated and running at full speed. I recommend this brand.Good fitSeems to be average to good quality
