We've tested Prologo's CPC – 'Connect Power Control' – technology before, and although it was impressive, it did cost £199, which will be an off-putting factor for many people.
Prologo is now offering CPC on its stainless steel Tirox-railed saddles. At £134.99, it is still expensive, but at 229g it is just 15g heavier than the model with carbon rails, and alloy-railed saddles from the likes of Fi'zi:k.
CPC technology has previously been used in Formula 1 - the extreme grip it offers is ideal for driving gloves. The surface of the CPC polymer is formed into thousands of hollow volcano-shaped cylinders. These lift you away from the main surface, which Prologo claims reduces fatigue and has a massaging effect. But those volcanoes also create a vacuum, holding and gripping you and giving you more control.
The Nago Evo shape sits between a rounded design like San Marco's Concor and the flat profile of Fi'zi:k's Arione, and it appeals to a wide range of riders. It's available in 134mm and 141mm widths and has a fairly pronounced nose to heel curvature, though the deep multi-density padding hides the shape a little. The hull has machined slots at key points, which add flex and up the already impressive comfort levels.
It's hard to say whether the CPC polymers do stave off fatigue or offer the claimed massage effect, but it is clear that there is no better saddle to ride on in the wet, while the saddle's surface makes it feel much more padded - and more comfortable - than its minimal proportions would suggest.
Overall the CPC technology has convinced us, and with little weight penalty in opting for the Tirox rails over carbon we've no hesitation in giving the Nago top marks.
