In terms of the ride itself, Tannus's tyre feels a little bumpier than a pneumatic tyre, which is because they contain less air to cushion blows from the road. However – and here's the clincher – if someone didn't tell you that you were effectively cycling on solid rubber, you probably wouldn't guess. And as the tyres are just as light as a normal rubber tyre plus its inner tube, your bike feels no heavier with its new set of shoes.
