Reviewed by LER - 15th Sep, 2018 Fantastic Inner Tubes I have been using these over the summer for commuting to work and going on leisure rides along some off road tracks. They are the best inner tubes I have used in a long while. They have a good thickness of rubber so that they both hold the higher pressures of 80psi and also they don't tear or become weak. This overall means much less time worrying about flat tyres and means you spend more time riding your bike hassle free! A very good price also. Please give them a try!
