Cornering traction might be a different story, since TT bikes aren't built for crits. |

Overall, I wonder how something developed for low rpms can suddenly be suitable for a far higher revolution use. |

Talking to wheel chair users, generally the inflated tyres are preferred for less rolling resistance. |

Cornering traction might be a different story, since TT bikes aren't built for crits. The image I saw showed mesh, so I'm wondering how they sealed it to inflate/pressurise it. They don't. It's "airless". If you look closely at the tires on the TT bike, you can actually see right through them. Overall, I wonder how something developed for low rpms can suddenly be suitable for a far higher revolution use. CAD/CAE. As the article I posted notes: "According to STC, a prototype version of the tyre that was built to simulate a standard pneumatic tyre inflated to 100psi has been ridden by the test team and the difference between the Metl tyre and a pneumatic tyre was “not noticeable”." |
