kk6gan Posted June 15, 2021 Share A quick Google search says helium particles are a fair amount smaller than oxygen particles and this will lead to it seeping through the tyre walls Link to comment Share on other sites More sharing options...
HdB Posted June 15, 2021 Share Didn't Jan Ullrich's team use some specific gas in their TT bike tyres at some stage? Around 1999. Can't remember if it was helium or not. Link to comment Share on other sites More sharing options...

I haven't done the sums, but someone on the internet reckons a 15g saving on 25c tyres. Which is not much for a fair amount of admin. Link to comment Share on other sites More sharing options...
Jbr Posted June 15, 2021 Share I think GCN or GMBN have tried it, I think there was absolutely no difference EDIT : can't find it, but you can watch this :Â Â Edited June 15, 2021 by Jbr Link to comment Share on other sites More sharing options...
