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.


  • Wide anatomical channel (PAS Technology) runs through the center of the saddle to reduce the contact of soft tissues and numbness
  • Designed with focus on extra comfort for all-around category end-users and both genders (Female & Male)
  • Space Technology is designed to fit riders that need a semi-round or round shape, with "medium-low pelvic rotation/flexibility. Used to help riders with less pelvic rotation and wider ischial bones
  • 7mm of added padding to increase comfort
  • Injection carbon monocoque base

Prologo Dimension Space Saddle (Grey/Black) (Tirox Rails) (153mm)
My new bike came with a pro logo 143mm saddle. I was having some, I'll just say comfort issues. To saddle fitting machine at Performance recommended a 155. I picked the pro logo 153mm figuring 2 mm was close enough and I wanted to keep the same brand on my bike. I am very happy with this saddle. It instantly felt better and more comfortable. The side taper is just right, it doesn't dig into my thighs but still wide enough for support. I like how it's shorter in the front. The only negative I've noticed is that the surface is a little slick. It took a little getting used to but it is probably better than the one with the grip that locks you in.

More than the seat itself, I'm extremely happy with the service I got at Performance bicycle from Peggy and Darnell. They were both extremely helpful in getting the right saddle.

Good saddle, very lightweight. Looks amazing. I upgraded from my stock specialized bridge-not more comfortable but is much lighter and looks great.
