Tubeless mountain bike tires definitely have their good points, such as
lower weight, less flats and decreased rolling resistance. In order to
seat the things securely on the rim, however, it's often necessary to
use a compressor or a CO2 cartridge to deliver a high-pressure shot of
air. That said, there's now another option, in the form of the Airshot.
When it comes to inflating bike tires on the road, there are two
options: a compact hand pump that requires some exertion, or a
single-use CO2 cartridge. New York-based DesignAir Innovations, however,
has created another one. It's called RideAir, and it's refillable
portable compressed air pump.
Tubeless tires have become pretty much standard on higher-end mountain bikes, thanks partly to the fact that they're able to self-seal small punctures. When it comes to larger holes, however, they need a little help. That's why award-winning South African competitive cyclist Stefan Sahm created the Sahmurai Sword.
Although we've seen a lot of interesting ideas regarding what may be powering or guiding the cars of the future, it seems that those vehicles' tires don't fire the imagination in quite the same way. Korean tire manufacturer Hankook is trying to change that, however, with its Hankook Tyre Design Challenge. Here's a look at the student-submitted concepts that took the top prizes in this year's contest.
Tubeless tires are pretty much standard on higher-end mountain bikes now, due to their lower weight and rolling resistance, along with their ability to contain sealant. However, they do have one drawback – you need to use a CO2 cartridge or an air compressor to put the things on. Bontrager has set out to change that, with its TLR Flash Charger pump.
Back in February, we heard about a prototype Schwalbe mountain bike tire system
that used a dual-chamber setup to both increase traction and
minimize flats. The design has since been refined, and the commercial version of the product was officially unveiled last month. It’s called Procore, and we had a chance to see how it works at Interbike 2014.
There may soon be a new use for discarded tires ... besides turning them into mattresses for cows
, that is. Researchers from the US Department of Energy’s Oak Ridge National Laboratory have devised a method of harvesting the carbon black from them, and using it to make anodes for better-performing lithium-ion batteries.
Although tire pressure monitoring systems are becoming increasingly common on four-wheeled vehicles, they're still quite the rarity on two-wheelers. RDV Labs, however, wants to change that. The San Francisco-based startup's CycleAT system is designed to continuously monitor the air pressure in motorcycle and bicycle tires, relaying that information to the rider's smartphone in real time.
Studded tires may make it easier to drive on ice, but those same studs will quickly wear down when used on dry asphalt – plus, they'll create a very rough, noisy ride. The problem is, most winter drivers encounter both types of road conditions, often even on the same trip. That's why Nokian has created a snow tire with retractable studs.
So, you've upgraded your mountain bike's clincher tires to tubeless, and now you figure you're all up-to-date and on the cutting edge, right? Well, perhaps not for much longer. German tire-maker Schwalbe and bike parts manufacturer Syntace have developed a tubeless dual-chamber
tire and wheel system, that they claim should offer better performance than your current old-school single-chamber tires.
