Prologo Zero C3 Nack is all you could want from a saddle – and better had be, for this sort of cash

Our review

A great balance of solidity and suppleness – but all this quality isn’t cheap...

Prologo’s range-topping Zero C3 saddle follows the same shape as its cheaper Zero models – but that’s where any similarities end.

  • Highs: Fantastic shape, comfort and finish
  • Lows: Rather a lot of cash for a saddle

The C3 is constructed using a full carbon composite base, into which Prologo’s Nack rail is bonded. Rather than a standard carbon rail, this is carbon fused with Kevlar and aluminium, which is claimed to create a much tougher rail that won’t deform under prolonged use, while still remaining as light as those of the competition. Our 132mm wide test model weighed 154g (claimed 145g).

The flat profile is designed very much for racing, yet we found the inherent give in the carbon hull made it a comfortable option for endurance riding. The flex only comes from the saddle’s centre so it still feels completely stable with no twisting or dipping from the flanks.

The top-grade high-density foam under the beautifully finished matt cover further enhances comfort. We were particularly impressed with how well it copes cushioning your hindquarters over rougher roads, its perfect mix of solidity and suppleness providing exactly what we appreciate from a saddle.

Its 270mm length gives you plenty of room to shift your weight around and the slender, narrow nose is extremely well padded. That means you stay comfortable even when moving your weight forward to hammer along on the flat or up a climb.


We make no bones about this being a pricey investment (it’s a hell of an outlay, no matter how well it performs) but it does have everything you’d want – great shape, comfort, low weight and a stunningly good finish.
