Tube or no tube is not my reasoning for ditching tubes itÃs the use of sealant.
I was getting a lot of thorn punctures since moving and being able to ride to my local trails along BWs/ towpaths. For about 6 monthsnow I have used 819 rims with rimstrips and normal tyres or proper USTs. Only had it go down once when it was really below freezing and it pumped up on second try and stayed up.
I use heavy tyres and still put 40psi in. I think it is smoother but itÃs a minor bonus.
TJ is once again talking utter shite, but hes dead clever so I must be wrong.
