    blog latest, I put some Foss tubes on my best bike

    These are kind of “super” inner tubes, lighter, stronger etc

    I’d be interested to hear from anyone that’s used them

    I was racing last night, and
    I was racing last night, and because the race wheels are retained centrally for major events this year, I was racing on ‘training wheels’ which run Conti GP4000s tyres and standard tubes. I happened to throw a leg over a bike running decent tubs, and the difference was obvious.

    Indeed when I throw a leg over my bike with race wheels in, the difference is clear… never underestimate the difference good rubber can make to the feel of a bike.

    Now, what that difference equates to in real speed is hard to say without doing some proper tests, but it does feel better.

    Saying that, if you run a decent set of racing tubs on a set of resistance rollers, you do go noticeably quicker than on a set of standard clinchers and tubes.

    By a “bit of garden hose” I assume you mean something like a Marathon Plus or a Conti Ultragatorskin

    I’m running Michelin Optimium Pro, which are 25mm and are essentially Michelin Pro Race 3

    I’m pretty sensitive to the suppleness stuff so I’ll bare that in mind, thanks

    compliant? I’ve always wondered about these claims made on inner tubes and their effect on ride quality. I’ve never ridden on latex tubes, but i don’t believe for one second that they make a perceptible or measurable difference to ride quality.

    I’ve used them… And I
    I’ve used them… And I think they are pretty good puncture wise… And a good option for training

    One downside of these is once they are used they stretch. So if you change your tire, its difficult to re-use the tube..

    I also think they are not as compliant as a normal tube… So the ride is not as good.

    I don’t know about the
    I don’t know about the puncture resistance claim but 103g isn’t especially light for road tubes – standard road tubes like Schwalbe SV15, Conti Race Light 28 etc are 100~110g. Michelin Aircomp Ultralight and Schwalbe SV20 are about 75g.
