• Yes comfort, because my Voyager Hypers are more comfortable without tubes.

    I'm not talking from a racing perspective because I don't! But I don't think most people who buy gp4000s use them for racing either so I expect that will also be true with the gp5000s.

    Isn't increased comfort a benefit in racing too, especially for people like you who go a really long way with a sore gooch?

    If the real world puncture protection is less good that's put me right off them though.

  • Most people who buy race bikes don't race them. People could save a lot of money using if they used proper commuter/training tyres rather than race tyres but then again people also put spoilers on their 1.2L Fiats and vote Leave so many are clearly idiots.

    It depends what 'edge' you're talking about then. What you wrote made it sound like you were claiming they were faster even though they had worse Crr. I would be amazed if I noticed any change in 'comfort' but less work is less work so I'll take the lower Crr every day (except they're not as puncture resistant so lower Crr becomes useless if your time is then lost with more punctures)
