Hidden behind all those acronyms, there’s a lot of saddle tech built into the Prologo Scratch 2 CPC PAS saddle
The Prologo Scratch 2 CPC PAS saddle has had a lot of the company’s top saddle tech thrown at it. I like the Scratch 2’s rounded profile, which seems to suit my sitbones well, even in its more standard versions. The Prologo Scratch 2 CPC PAS saddle is available in 134mm and 143mm widths – we’ve tested the narrower version here.
First up is the CPC. Standing for Connect Power Control, this is a Prologo exclusive design made up of sections of material containing a series of small hollow centred cooling tower-shaped protuberances – the matt black parts of the saddle top.
These grip the surface of your shorts and keep you from slipping around as you pedal. I definitely found that they helped me keep my position on climbs and harder pushes, but they weren’t uncomfortable and still let me adjust my weight when I wanted to.
I only rode the Prologo Scratch 2 in dry conditions, but Prologo says that the technology is particularly effective in the wet. It also claims that you get better air circulation and additional shock and vibration damping from their raised structure, as well as a massaging action that increases comfort.
PAS stands for Perineal Area System. It’s the central pressure relief groove on the saddle top – a more standard option found on other makers’ saddles too. The groove stretches a long way down the saddle’s surface, with its front end a couple of inches behind the saddle’s nose.
I sometimes don’t get along with cut-outs and grooves on saddles, but the Prologo PAS groove is not noticeable when riding and doesn’t detract from saddle comfort.
Finally Prologo says that its Ergo Shape Design gives a sloping cross-sectional profile to the central portion of the saddle to allow a better cycling position.
In addition, Prologo say that it uses three different foam densities in the saddle’s top. The rear of the saddle, which carries most of a rider’s weight has high density foam for stability. The middle of the saddle is made of less dense foam for reduced pressure on the pelvis, while the front uses lower density foam still to protect the sensitive soft tissue.
The test Prologo Scratch 2 saddle sits on alloy-steel Tirox rails, which helps to explain its quite high weight of 234g. There’s a version with Nack carbon fibre rails available too for reduced weight, claimed to be 185g, but with a price £75 higher at £250.
I’ve found the Scratch 2 CPC PAS saddle really comfortable for longer rides. The profile works well for me, it’s nicely padded and the CPC grippers help stop you hold position whilst you ride.
