The Saddle That Won The Tour de France In 2020 & 2021

Introducing the Prologo Scratch M5 PAS Saddle, outfitted with a pressure reliving cut-out and the MSS (Multi-Sector System), which creates 5 mapped zones that support the rider in aggressive and non-aggressive positions.

Climbing, sprinting, or long stages — no matter the challenge faced, the Scratch M5 was Pogacar's perfect ally to become the best climber, the best youngster, and the best overall in the Tour.

Scratch M5 / Scratch M5 PAS is the new line of saddles that uses 4.0 technologies; innovative in terms of size, shape, and ergonomics, they are suitable for many uses and disciplines (Road/Off Road/Triathlon).

Thanks to the new design, size, and ergonomic 'T-Shape,' The Scratch M5 PAS is suitable for both male and female body geometries.

The new MSS (Multi-Sector System), designed in collaboration with the Politecnico of Milano, improves comfort and performance. The active foams, separated from each other, create 5 mapped zones that work individually, supporting the normal pedaling movement both during the pushing and pulling phases. The round shape of the Scratch M5 allows the pelvis to rotate naturally, creating stability and support for the lumbar areas; it also favors the distribution of pressure over a larger surface.


  • Suitable for male and female body geometries
  • Pressure relieving cut-out
  • Ergonomic 'T-Shape'
  • MSS (Multi-Sector System)
  • Size: 250x140mm
  • Saddle weight with Thyrox (alloy) rail: 185g

A firm but evenly supportive saddle with great pressure relief and good comfort in all riding positions.

Using this saddle on my gravel bike. Overall I like the shape of the saddle. I'm coming from an older model Specialized Phenom in a 135mm width, and this saddle provides much more comfort in a variety of positions. whether on the tops, in the hoods, or in the drops, support is even in all positions. I have yet to feel like I'm sliding forward onto the nose (it is slightly wider than what I was used to, but has not been an issue); nor do I get the pressure from the nose of the saddle that I was getting from the phenom.

I've only completed short rides (1.5-2 hrs) so far, so looking forward to seeing how longer rides play out (would feel more confident giving a 5 star rating if I had these rides under my belt).

When handling the saddle the padding feels VERY firm, but despite how firm it is the pressure is very evenly distributed on the bony anatomy and hasn't caused any kind of pressure points or soreness.

Prologo Scratch M5 PAS Saddle could be more comfortable

I'm 72 and I ride 1800 to 2000 miles per year on pavement. I started training and racing about 46 years ago on a Cinelli Unicanitor saddle, and always liked the rounded, saddle-like shape. I rode for a few years on an Italia Flite, that was on my bike when I bought it, but that felt like riding on a seat cut out of plywood. Never got used to it. I tried an Italia Turbo, because it was similar to the Unicanitor, but I needed a saddle with a cutout. I looked at a lot of pictures online and bought the Prologo because it appeared to have rounded sides. It's shorter than I expected, and not ideally anatomical on the sides, but it's way more comfy and anatomical than the Flite. I'd like to see a saddle with about the same cutout and shape, but deeper sides.

I like this saddle on my road bike, but saddle fit is so subjective. One brand or model may fit a particular rider and another won't so I'll provide comparisons to gauge if this one might be right for you. Prologo's Nago X10 and Zero saddles are a couple of my favorite MTB and gravel saddles. I guess Prologo's generally work for me, and if that's you, the Scratch M5 is probably a good option. I like Selle Italia SLK/SLR styles too, but this Scratch M5 PAS feels like an improvement. On the other end of the spectrum, I can't ride Fizik saddles. I've tried the very popular Arione, Aliante, and a couple of other models I've forgotten and they just don't fit me.

Some comments specific to the Scratch M5 is that I don't notice the shorter nose when riding so that's a good thing. I do think the nose mid-section is a bit wider (maybe 3mm?) than I'm use to; this doesn't make it uncomfortable but just a bit more thigh rub as I break in the new saddle. I do really like the saddle's 'T-Shape', and while it doesn't look like a 'T' to me, it feels like there is something to press on in a climb. Finally, I've seen the saddle described as hard, but I'd say it is simply firm and that suits me.

This saddle is pretty comfortable and well priced with similar saddles. I have been getting used to it riding indoors for about 3 weeks now. I barely feel any pressure after rides of up to 2 hours where with other saddles I would start feeling pressure after 1 and a half hours
