Product Description

Prologo Scratch M5 PAS w/ TiroX rails

prolog scratch m5 PAS Road gravel triathlon TT saddle seat bike bicycle

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), including the Triathlon. Thanks to the new design, size and ergonomic "T SHAPE", SCRATCH M5 PAS is suitable for men and women.

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 favours the distribution of pressure over a larger surface.

The PAS (Perineal Area System) is a channel designed to eliminate pressure peaks and numbness, improving blood flow. Its particular ergonomic design, assisted by variable density foams, eliminates contact points in the prostatic-genital area. The PAS channel is ideal for users who prefer performance combined with comfort over long and medium distances.

Package Includes: 1 Prologo Scratch M5 PAS Saddle

Prologo Scratch M5 PAS MMS road saddle seat bike bicycle

Technical Features and specifications

MSS - Multi Sector System: Three different individual zones mapped and separated along the saddle, each composed of different interactive foams and single-cell padding. These areas work independently adapting to all the positions that cyclist can take.

PAS: Perineal Area System (PAS system) is a channel designed to eliminates numbness and reduces the compression of soft issues, improving blood flow in the pelvic area.

The Shape: Round Saddle Shape design is ideal for a rider that has less flexibility in their lower back and a low amount of anterior (forward) pelvic rotation.

TiroX Rails: Light-alloy steel, highly resistant to traction and torsion, for its physical characteristics and light weight is also used in the aviation and aerospace industry. Tirox is a great balance between weight and strength, that doesn’t fear the normal stress. Max torque of 12Nm

Dimensions: 250 mm x 140 mm width

Weight: 189 grams

Product Description

The Scratch M5 is the new line of saddles that use 4.0 technologies; innovative in terms of size, shape and ergonomics, they are suitable for multiple uses.


Thanks to the new "T SHAPE" design, size and ergonomics the M5 Scratch range is suitable for use by both men and women. The measurements are 250 x 140mm in width. The new MSS Multi Section System seating system, designed in co-operation with the Politecnico of Milano, helps improve comfort and performance; the active foam separated to create 5 zones working in a smart and individual way favoring the natural movement of the pedaling movement. This absorbs the vibrations that the carbon fibre body transfers to the over-saddle. The Round Shape of the M5 creates stability and support for the lumbar areas; moreover the distribution of the pressures on a greater surface.


The PAS system is a channel in the base of the saddle. The hole or channel helps to maximises blood flow and supports the pelvic area while also preventing pressure peaks. This system is designed and developed to eliminate pressure and numbness to areas that need it most.

I got one of these when they first came out almost three years ago. They weren't available in the US then so I ordered it directly from the manufacturer in Italy. Now I want the same saddle for my commute bike, so I ordered one from Amazon and it just arrived. It's the real deal, exactly the model shown, not a lower priced substitute. This is the saddle the past 2 Tour de France riders used (2020 & 2021) so they're popular and they can be hard to get, so if you're looking for this saddle you shouldn't worry about ordering it from Amazon - it's a genuine Prologo Scratch M5 Pas.

I've recently tested this saddle up for about 200 miles up against similar mileage for a Selle Italia SLR Superflow, a Brooks C15 Cambium, a stock Bontrager that came on my Trek Domane and a few others. My bike geometry is such that I needed the thinnest saddle height so that my bottomed out seat post and saddle/frame thickness wouldn't put me out of my ideal seat position. The Selle Italia was as thin, but just a bit too long and getting caught up in my shorts. Although the Superflow has a decent cut-out, for some reason, it was bothering my groin area/junk. This Prologo short nose is thin and with a decent set of bibs, it is the most comfortable of those I've tried. It is a bit stiff compared to plush saddles, but for my riding style and good bibs, I have No complaints.

Have used this saddle since June 2020. No complaints. Was getting bruising and chafing from other saddles and initially from this one; in that search for the Cinderella saddle, I tried the Fizik Tempo Argo R3 in 150mm, but the relatively flat, flared sides left deep bruises. Returned to this saddle, as it has a more rounded profile, and paid more attention to seat height and saddle adjustment (angle, fore/aft). Now, the miles just roll without discomfort. Big plus are the extra long rails that allow for a wider range of fore/aft experimentation.

I ride a Tarmac with a short frame (52). Whenever i was starting off, i was always snagging my bike bike shorts on the nose of the seat. I would end up bouncing in the seat until it unsnagged. Not a huge deal just big annoyance. Second I experienced a bit of perineum discomfort no matter how I adjusted the seat. Both situations were addressed by the seat. The cushioning (if you can call it that in a performance saddle)still is a bit stiff after only a few hundred miles but I expect it to improve over time. Overall, I'm pleased with the purchase.

Love the Prologo saddles! I have the Nago Evo Pas CPC 141 mm version on my road bike and love it.
Just started using this M5 on my gravel bike. The narrower 141mm fits me better and so far, it feels great out of the box.

WARNING: The cost of the return is greater than the cost of the product with taxes... Cost of the chair 138$, cost of return shipping 150$. The product is not of good quality, it is hard, heavy and does not look well finished

Nei mie trentanni di mtb non ho mai rotto una sella, acquistata in sostituzione dell'originale sempre uguale a questa che si è rotta a metà, ho l'impressione che non duri ancora molto, probabilmente cambierò modello, devo dire anche che in assetto da bici con zaino sono sui 92 kg
