Dynaplug’s new composite Carbon Racer tire plugging tool drops 40% off the weight of even their lightest alloy Dynaplug Race for what shapes up to be “The World’s Lightest Tire Plugging Tool”. No need to weigh yourself down to be able to repair tubeless tire punctures on the go, just clip one of these suckers behind a bottle cage or into a bag, and you’ll forget it’s there… until it saves you from walking home. We even hear a big bike company will be including one with their next new race bike, very soon…

We all know by now that tubeless tires are faster to ride, offering more control, more comfort, and decreasing the number of flat tires. But punctures still happen, and Dynaplug has made a name for itself creating some of the best tubeless tire plug tools available. Now their Carbon Racer dials the weight back even more with new composite construction.

We’ve already used the new plug tool to fix a sidewall puncture when we got “a little too rad” on an off-camber landing, and it’s held air flawlessly on subsequent mountain bike rides.

Carbon Racer – Tech details, pricing & availability

Curiously, the Dynaplug Carbon Racer isn’t made from carbon fiber. Its body is actually molded from 30% glass fiber reinforced nylon, which gives it a carbon-like matte black look. The double-sided Carbon Racer features one smaller road diameter insertion tube to fit regular plugs, and one larger MTB diameter insertion tube to fit Mega plugs for bigger punctures on the other end. (A road specific version with two of the smaller diameter tubes will also be coming soon.)

The whole thing, with nylon covers on either end weighs just 14g (down from 23g for the alloy Racer). Throw in the included Carbon Silicone rubber tool holder that mounts behind a bottle cage for another 10g if you don’t want to put the 11mm diameter x 95mm long Carbon Racer in your pocket, saddlebag, or CamelBak.

As for availability, we hear it’ll be coming very soon as standard equipment on a new Cannondale. But in the meantime, you can get one now directly from Dynaplug for $48. That includes the Carbon Racer tool itself, three regular pointed-tip plus, two bullet-tip Megaplugs, and the rubber cage mount (that also fits the alloy Racer.)

    Cory, what does that mean, ‘faster to ride?’ I dont know that tubeless are ‘faster to ride.’
    I have a bike with tubes that havent flatted in years & a tubeless bike that I have to add air more frequently than the other…
    And I achieve faster speeds on the tubed bike, so what are you talking about??

      @Tubee We’ve seen numerous data indicating that factoring in equal tire construction, tubeless tires roll faster with less rolling resistance than tubed or tubular tires. Here’s a fairly recent article presenting such data by Tour-proven Specialized tires. Similar data from Continental, Pirelli & Schwalbe, for ex. suggest the same for road tubeless being faster.

      Having to continuously add air suggests an imperfect tubeless seal between tire, tape & rim, or the sealant not living up to its job, or some other breakdown in the tubeless system. I confess that I have a few tubeless tires that require regular pumping, but just as many that need air at most every couple of months.

        Thanks Cory! I’m still not convinced that tubeless are the way to go on my road bikes, but to each his own!

        Tubeless is just a way to increase the puncture resistance/survivability of the system. If you have two tires, one tubeless and one not, that are truly similar in construction, the tubeless version will have greater puncture survivability, but the .crr will be similar (assuming a latex tube in the tubed version). If anything, the tubeless version will have a slightly higher .crr due to the added layer of airtight coating on the inside of the tire. Nothing about tubeless itself makes the tire faster. Putting a latex tube in a tubeless tire does not increase it’s .crr.

        What latex does is allow tire manufactures to alter the construction, going farther with the things that make a tire fast (thin tread; thin, highly pliable carcass; minimal or no anti-puncture belt), while still meeting their reliability targets. This is why we’re seeing tubeless emerge as the construction method of choice for the fastest tires. If Vittoria built a Corsa Speed that wasn’t tubeless (didn’t have the sealing layer), and you used a latex tube in it, it would be even faster than the tubeless version. It would be terribly prone to punctures, though.

          My inclination was to question you claims, but after checking you’re right. BicycleRollingResistanceDotCom has tested the Conti GP5000TL with 20ml of Stans sealant and a Conti GP5000 clincher with a latex tube, and the difference in power required to overcome rolling resistance at 4 different inflation pressures (60, 80,100, and 120 psi) was between 0 and 0.2 watts. The average difference was 0.1 watts. I’d call that a wash

    I love my aluminum Dynaplug Racers. These work really well, but at $48, the price is VERY steep for what you get. They are CNC machined in the US so, that’s something. Now these plastic version is the same price? There is no way it costs half as much to make these. Hopefully this is an introductory price.

    I do like the mount. I keep my ‘other’ branded ones taped under the stem. Being able to get a plug into a puncture faster seems to help before too much sealant is lost. You only have to try digging through your pack while keeping a finger on your tire once before realizing these things are supposed to be kept where you can quickly access them.
