This popular 700x 25c tyre has low rolling resistance & the equivalent of 105 PSI hardness, which delivers great speed across the ground with slightly more cushioning than our high-performance Slick tyre. Perfect for serious road cyclists who want a more comfortable ride. The New Slick provides superb grip in all riding conditions & like all solid Tannus Tyres, is completely puncture-proof & extremely durable. The 700×25 is designed for a modern, wider rim. The inner rim width should be 16-18mm
