We’d say that the average price for a good performance saddle is probably around the £120 mark, but if your budget stretches a little further then the Prologo Zero II is certainly more than worthy of consideration

The headline feature of the Prologo Zero II is the Connect Power Control (CPC) technology. This is basically dense bunches of tiny suction cups strategically positioned across the saddle’s surface, greatly improving the grip of the saddle. Similar systems have been used in the gloves of Formula 1 and MotoGP racers for a number of years, but Prologo is the first company to apply it to cycling products.

>>>Saddle height: how to get it right, and why it's so important

On the road we were impressed with how well the CPC technology worked in practice. Even when riding in an aggressive position right on the tip of the saddle, you’ll find your rear kept firmly in place, rather than shifting backwards as is the case with other saddles.

The Prologo Zero II is marketed by the Italian company as a saddle for short to medium length rides, but to be honest, we’re not sure why. Even on rides of 4-5 hours we rarely suffered any discomfort, and we’re impressed by the ability of the stainless steel rail which did a great job absorbing road buzz.

Perhaps some of this comfort can also be attributed to the CPC technology, which Prologo claims also acts as a shock absorber, reducing muscle fatigue and improving recovery time after riding. Anecdotally we didn’t notice too much of a difference in recovery times, but if there’s any improvement at all we’ll certainly welcome it.

At 250g there are certainly lighter saddles on the market, but the Prologo Zero II is a great all-rounder that provides excellent performance and comfort at a decent price, and we certainly couldn’t ask for too much more.
