Launched as part of Prologo’s 2020 range, the Scratch M5 series is a range-topping saddle that follows the trend of short nose saddles and measures in at 235mm from nose to the end of the padding (250mm full length) with a 140mm width. The Scratch M5 is a saddle that features on an extensive number of pro teams bikes including Astana, Bahrain-McLaren, EF Education First, Groupama-FDJ, UAE Team Emirates

Prologo aims its Scratch M5 beyond just road riding stating that the shape and design transfers to other disciplines including offroad activities and TT/triathlon. Available in both standard and cut out versions, it makes use of many marketing acronyms, one of which Prologo calls 4.0 technologies. While Prologo is vague regarding what these 4.0 technologies actually are, it all comes together to form a well-rounded saddle.
