Saddle styles have dramatically changed. Prologo's Dimension project is no exception to this snub-nose, wide-tailed saddle approach. It is all about comfort, performance, lightness and preventing perineal area problems. The project resulted in a saddle unlike anything Prologo had created. The saddle has a short nose (3+ cm shorter than a traditional saddle) to reduce contact and pressure in the frontal area, especially for low position riding, like riding in the drops. It also features a wide tail for improved stability, weight distribution and power transfer.


  • Increased 143mm width distributes the athlete’s weight across a larger surface for comfort over the long haul 
  • Wide anatomical channel (PAS Technology) runs through the center of the saddle to reduce the contact of soft tissues and numbness

Prologo Dimension Tirox Saddle (Black) (143mm)
This doesn't look particularly comfortable, but it was a huge step up from an older style Bontrager seat. One thing I did notice quickly; there is a relatively narrow sweet spot to make it just right. At first I thought I had just erred in the seat purchase, but with a little down angle and moving it back a little more than I would have imagined right, it was really nice. It has just enough wiggle between the two effective halves of the seat to smoothly shift your weight side to side when you are working at it, and is comfortable with touring. I love having that absent middle segment; amazing difference from older style seats.
