Know more Tubeless
Ever since the invention of the “wheel”, mankind has been on a constant search for a way to make them more efficient.
For over half a century the Car and Motorcycle industries have long known the benefits of having a lower rolling resistance to improve rolling efficiency and fuel economy. Yet within the Bicycle industry it has really only become a key focus in more recent times. So why has it taken so long for them to catch on?
Minimising the rolling mass of a wheel involves reducing the bulk of a wheel’s “weight” from the outer most extremity of its diameter, so that it’s “centre of gravity” remains closer to the centre of its circumference, around the ‘hub’. The easiest way to do this within a wheel / tyre combination is to reduce the mass of the tyre and tube.
With bicycles (Mountain Biking and Road Cycling in particular) for the past decade, the most common approach was to reduce the tyre weight. By adjusting the compounds and thickness’ (especially within the sidewalls) and by reducing the amount of models produced containing Wire Beads, tyre manufacturers have been able to significantly reduce the weight and therefore rotating mass or their tyres whilst maintaining a durable and grip inspiring casing.
However… This has only taken us so far. When we reflect back at the Car and Motorcycle industries, their biggest advance in wheel efficiency has come from removing what was once a key component to ensuring the wheel provided an efficient yet comfortable ride without having to make them of cold construction, THE TUBES!
The rubber tube is without question, the greatest contributor of weight affecting rolling mass to a Bias or Radial tyre set up. By removing the tube, you are not only removing a substantial amount of a wheels rotating mass but you are also enabling it to be run at a lower pressure (PSI) with a reduced risk of obtaining a “pinch” flat or puncture. Running a tyre at a lower pressure also allows the tread surface to make greater contact with the terrain providing the vehicle with more traction.
The biggest obstacle with converting a tyre to tubeless has always been finding a way to contain the air pressure within the rim / tyre combination. The revolution (for bicycles atleast) came with the introduction of “Stan’s No More Tubes” tyre sealant. This sealant contains a special low viscosity liquid that coats the inside of the tyre and carries with it specially formulated “sealing crystals”. when there is a puncture the low viscosity of the sealant finds it’s way around to the leak quickly and the crystals work by sealing the larger holes. It can remain liquid within the tyre casing for months before needing replacement or until it is required by the presence of a puncture. Most other brand tyre sealants will work in much the same way. This along with the introduction of specific rims and tape and it makes for quite a good system. Providing you use a high quality, self sealing Tubeless Presta Valve. Enter in WISTIO.
Presta valve is a very small part onto your bicycle, but it is so important as brake.
Wistio have been manufacturing Tubeless Valve products for quite some time now and are among the industry (If not, the world) leaders in Tubeless Presta Valves and Accessories. They have a wide variety of valve styles to suit rim types ranging from the original Stan’s Tubeless Ready rims, American Classics, Mavic, Enve Composites, Zelvy, etc… Infact their tubeless ready presto valves are so versitile that even converting non tubeless ready or even cheap, entry level rims & tyres to tubeless is a breeze! They also come in a wide variety of hard anodised colourings to choose from to give your ride that personalised touch.
It may have had slow beginnings in the world of cycling but the tubeless revolution has finally arrived and is here to stay.
