If your rim tape is not properly installed, a latex tube is likely to find its way into small gaps, causing it to tear. If you don't want to go tubeless, consider the latex inner tubes which will save you 8 - 12 watts for a pair of mountain bike tires when compared There is a weight advantage for the tubeless set up and latex tube. Sa composition chimique lui confère une élasticité, ce qui est son attrait majeur du marché avec les consommateurs. For a detailed explanation, read my special article about For consistency, the tyres were inflated to 100psi; each set-up was ridden at 280w for five minutes to allow it warm up, whereupon they were ridden at 300w for five minutes. Fitting the One V-Guard with a light butyl tube gives a small improvement over the standard butyl tube. Because the Schwalbe One is also available in a tubeless option, this will be a four-way comparison. Let us know down below. Log in. None of this is a problem in tubular tyres. The fit. Part IV: Why Riding With A Cyclist Mentality Is Dangerous, Anti-Aging: Consistency, Specificity and Variety. The main problem arises with seating the tube inside the rim and making sure it doesn’t get caught under the tyre bead. I tried latex tubes for a short while some years back. long. With heavy braking, such as while descending, you can cook the wheel rim and high temperatures can cause a latex tube to burst. The test compared the weight and rolling resistance of butyl, latex and Tubolito inner tubes. However, the argument for tubeless on the road has never been nearly as clear-cut. Some brands also sell ultra-light butyl mountain bike tubes, which have a weight of about 150-160 grams for the 29-inch version. you might need a bit more when going off-road. Yes — cost. I'm surprised by the performance of the latex inner tube, The lorry is driving towards the junction at low speed, the cyclist passes, the lorry pulls out. Occupying the lanterne rouge position was Continental’s workhorse 23mm-wide tube-type GP4000, which, according to AeroCoach’s testing, required almost 12.5 watts more effort to maintain 45 km/h than the 25mm-wide tubeless Vittoria Corsa Speed. They’re made to go fast for short distances on good surfaces, and that’s about it. To view all specifications of these tires you can Switching your tires from butyl inner tubes to a tubeless set up with sealant will lower rolling resistance by 10 - 15 watts If you like road.cc, but you don’t like ads, please consider subscribing to the site to support us directly. With latex tubes and tubeless tires, you'll have to check the air pressure every ride. Consider, for example, the fact that Specialized-sponsored riders in the WorldTour have been dabbling with that company’s S-Works RapidAir tubeless tires, instead of the S-Works Turbo Cotton tube-type clinchers that AeroCoach’s data suggests are substantially more efficient. It did take three days to get the Race King to seal completely; it was leaking through the sidewalls quite a bit. The One Tubeless comes out just a little bit faster. The risk of punctures remains the although this risk doesn’t outweigh the gain for such a relatively short time on the bike. I received quite a few requests from readers who want to know how a light butyl tube compares to the latex tubes. quickly which means you have to check air pressure every day. Using a latex tube results in another small improvement. Difference between brands was minimum. rolling resistance. Five watts might not sound like much, but over the course of long rides or time trials, it’s significant. Subscribe to our newsletter for exclusive content, deals & events. We’ve reported on the company’s test results before, most recently regarding the new Continental GP5000 tyres. Whereas the latter has a gooey glue layer in between the rim and tire that sucks up precious watts, the former is more directly connected to the rim. However, there’s also plenty of testing data available that proves they’re substantially faster. To find out whether this was just marketing I wanted to see for myself, so I conducted an experiment: I fitted Continental Grand Prix tyres with and without latex tubes, rode them on a set of rollers, measured the power with a PowerTap G3 hub and recorded the speed achieved for a given power output. After using it for a while and doing these tests, article will satisfy anyone who wants to know the differences between tubeless, latex inner tubes, light inner tubes, and standard inner tubes. But, before we all go out and blow our hard-earned, are there any downsides? I tried latex tubes for a short while some years back. These light tubes are very thin, I blew the tire off the rim the first time, resulting in another trip to the store. files were processed and the inertia was corrected for each tyre. - The world’s lightest inner tubes? If you don’t want to subscribe, please turn your ad blocker off. The Latex tubes lost more than 3 bar. For everyday riding, however, you may want to rely on durability of a Butyl rather than the low rolling resistance of Latex, giving you a better chance of avoiding that inevitable puncture. I almost invariably ride solo, but I would be reluctant to ride 2 abreast in the narrow back roads of North Lancashire out of self-protection. This enables them to absorb the bumps in the road and flex around them better. Continental’s new 25mm-wide tubeless GP5000 TL required more than seven additional watts per pair to maintain the 45 km/h target speed, however, while the 26mm-wide Specialized S-Works RapidAir soaked up another five watts of rider effort on top of that. They recommend lightweight Butyl tubes for daily use. >>> Is graphene cycling’s next game changer? Elsewhere, the council have been repainting cycle lanes on Causwayside over the last couple of days; some sections now have solid lines. That's more than 15 watts of additional rolling resistance for a pair of tires! You have to take your time for the tubeless set up of Continental RaceSport tires. Where things stand for the NTT team, Philipsen sprints to victory on Vuelta stage 15, On Ian Stannard retirement day, let’s relive the time he walloped Quickstep by himself, Ian Stannard forced to retire from professional cycling due to rheumatoid arthritis, Preview: What you need to know about the Ceratizit “Madrid” Challenge. There’s a fair bit of anecdotal evidence that latex tubes are also more resistant to puncture and pinch flats than butyl, too. resistance that is lower than that of the One Tubeless. First look at Tubolito's lightweight inner tubes + video. The results were consistent with Vittoria’s claims and suggest that by using latex inner tubes you do indeed have lower rolling resistance, allowing you to travel faster for the same effort. Measurements are taken at air pressures of 15, 25, 35, 45 and 55 psi. As a result, most road riders still stick with tubes (and usually butyl ones at that) for pragmatic reasons. to butyl tubes. Help us to make it better. In this article, I will present all data collected from tests done with a tubeless converted tire and latex and butyl inner tubes. Parce que c'est un élasto depending on air pressure! read the individual reviews here and For those using clinchers, the most obvious benefit is for time trialling where a five watt saving could be the difference between winning or losing. They tested puncture-resistance, simulated ride over a sharp obstacle, rolling resistance and air-leaking! These frequently asked questions deserve an answer. it should be virtually impossible to flat. Alternatively, latex tubes like the ones AeroCoach used for testing here are a fair bit more expensive than even ultralight butyl tubes, and the more porous material doesn’t retain air as well long-term, either. Tubolito inner tube rolling resistance tests, Overview page with all mountain bike tires that have been tested, Rolling Resistance Coefficient (Crr) 55 psi / 3.7 Bar, Rolling Resistance Coefficient (Crr) 45 psi / 3,1 Bar, Rolling Resistance Coefficient (Crr) 35 psi / 2,4 Bar, Rolling Resistance Coefficient (Crr) 25 psi / 1,7 Bar, Rolling Resistance Coefficient (Crr) 15 psi / 1.0 Bar. The line chart says it all! The aero company, headed by Dr B Xavier Disley, specialises in optimising aerodynamics for cyclists and it has worked with Tour de France racers winners and stage winners, according to its website. Of course it is science. Fitting the One V-Guard with a light butyl tube gives a small improvement over the standard butyl tube. He's a seasoned cyclist of all disciplines, from road to mountain biking, touring to cyclo-cross, he only wishes he had time to ride them all. Latex inner tubes are faster-rolling than the regular butyl tubes used by most riders and are much more supple.
