Don't know if they are latex or not though but still without a doubt the lightest tube I've ever heard of. They aint cheap at £40 a pop though.

This was also something I also have done over the last 30-years but having disassembled thoroughly warn/punctured Veloflex road and FMB cross tubulars, I noted that both had a talc-like powder residue inside. Also wanted to add that in hot/humid climates like we have hear near the Texas Gulf Coast, in the summer time (May-SeptemberWMW wrote:Doesn't... just make it easier to do a good install and removal.

Also wanted to add that in hot/humid climates like we have hear near the Texas Gulf Coast, in the summer time (May-September), road temps often exceed 120+ degrees and adding talc helps keep the latex from sticking to the tire carcass. As for rolling resistance, I have always gotten the impression it helps by allowing the inner tube some 'wiggle' room inside the tire
Their press release says they are made of a "special plastic".
Vulcanizing patches like Rema Tip Top work just as well for latex tubes as for butyl.
