Prologo CPC Zero II Tirox saddle review

14 Dec 2016

If the flat shape suits you, you’ll find an impressively comfortable saddle featuring innovative technology

Prologo offers more types of saddle than I’ve had hot dinners, so although its range can take some time to get your head around at least you can be sure that within it there will definitely be a shape that suits you brilliantly.

Breaking it down generally, each saddle is based around five core models (Nago, Zero, Scratch, Kappa and TGale).

The models are then separated into several price tiers depending on the materials and technologies used.

Flat and narrow

The Zero II is at the racier end of Prologo’s spectrum, being flat and relatively narrow.

Due to its ‘aggressive’ shape, Prologo recommends this saddle for shorter, fast paced rides, but to me if a saddle suits your sit bones it will be comfortable regardless of how you ride on it or the duration of your ride.

I tend to suit flatter saddles so it was with little surprise that on the Zero II I easily found a comfortable, powerful position from which to ride. What was surprising however was the efficacy of Prologo’s CPC cover.

CPC (Connect Power Control) is a distribution of tacky polymer micro-cyclinders across the cover of the saddle that aim to stop you sliding around (an effect more inherently prevalent on flatter saddles due to their shape), so if you find a good position in theory it should be easier to maintain it.

It works very well, such that the technology was missed on saddles that didn’t have it after I used this one.


Prologo also claims that the technology dampens road buzz and improves airflow, but I can’t say I was attuned enough to notice any improvements in these areas.

The Tirox in the saddle’s name refers to the material used for its rails, which are a light steel alloy.

They add some weight compared to Prologo’s more premium NACK carbon rails used in higher tiers, but I like the versatility that their regular, round shape provides - the saddle can be used with any seatpost, whereas NACK oval rails require a seat post clamp to contact them only on the top-and-bottom.

Almost a decade of research informs Prologo’s saddles and this is clearly evidenced in the fit and design of the Zero II.

At £134.99 and 232g the Prologo CPC Zero II Tirox may not be the cheapest or lightest option on the market, but the fit of your saddle is an area that shouldn't be compromised in the name of performance.

Verdict: If the flat shape suits you, you’ll find an impressively comfortable saddle featuring innovative technology. From £134.99,
