New lightweight solid tyres hit UK

Korean brand Tannus launch faster rolling Aither 1.1 model

The UK launch of the Tannus solid tyres last year caused quite a stir on the Cycling Weekly website, much more than expected giving that this is a technology which has been knocking about for the best part of 130 years. Now the Korean company is bringing its lightweight solid tyre to the UK, with the Aither 1.1 set to launch next month at the London Bike Show.

Tannus claim that its new model is just as robust as the original Aither 1.0, meaning it should be good for 9,000 kilometres without losing more than 1.5mm of tread. It’s this incredible longevity as well as the incredible convenience of never puncturing that should go some way to justify the £119.90 price-tag for a pair (although Tannus are currently offering single tyres for £50 and a pair for £100 for customers using the code ‘londonbikeshow’).

However the new lightweight solid tyres are aiming to take on the pneumatic world head on. In fact Tannus claims that the Aither 1.1 will travel at 29kph at the same power output needed to ride a Panaracer road tyre at 30kph. Certainly good enough for training rides at least.

Of course don’t be misled by the ‘lightweight’ tag – these tyres may be lightweight for a solid tyre, but they’re certainly not going to be challenging lightweight pneumatic offerings such as the Vittoria Open Corsa SC or the Challenge Elite Open Road any time soon.

Still the claimed weight of 380g could be worse, and isn’t a million miles away from the combined weight of a Continental Gatorskin plus rim tape and inner tube.

The Aither 1.1 comes with a set inflation level of 100psi and will be available in 700x23mm in ten different colours, and 700x28mm, 700x32mm, and 26×1.75 in black.
