Prologo redesigned their flagship short fit on- & off-road saddle with this new Dimension R2 that shaves a full 15% of weight off its already light predecessor. The new saddle keeps the same overall V-shape and dimensions but leverages more advanced materials and carbon construction to shed significant weight. Plus, Prologo refined the Dimension R2’s ergonomics, reworking a 30% wider and more smoothly curved tip to improve rider comfort when perched on the nose of the saddle…

Prologo describes the original Dimension as their first short saddle, with an “innovative V-shape design [that] made it one of the most appreciated and used by many champions; a true icon both on and off-road.” With such a popular platform, they were a bit reluctant to change too much, so set about refining it.

What’s new?

The big highlight is ~24g weight reduction, mainly shedding grams thanks to a new lightweight EVA foam that gives the same level of support and comfort, but with 20% thinner padding. Otherwise, it features Prologo’s top lightweight Nack reinforced carbon rails and injection molded Long Fiber Carbon composite shell construction.

Equally important, the Dimension R2 gets subtle ergonomic updates, as well. Studying how to improve performance, Prologo gave the new Dimension R2 a 2mm wider nose with a more rounded profile for additional comfort. “In addition, the central part has been redesigned and has a flat surface, to facilitate an even more advanced and aerodynamic [riding] position.

This stubby saddle fad really bothers me. I use the full length of a saddle with normal dimensions on most rides. Why would anyone want less saddle real estate? I was told they were developed to help pros move their saddles as far forward as possible without violating a (ridiculous) UCI rule. Some saddle companies have stubbed their entire lineup just so people can look pro. But feel free to set me straight. Maybe they’re great and I’m an idiot.

Maybe short saddles work well for some people.

I don’t have one or fully understand, but maybe the rationale is to hang your taint off the front of the saddle when sliding forward so there’s less pressure on it, but it seems like it would reduce forward sliding range?

Maybe you just need to try one for yourself, then you can talk

Saddles are always a personal thing, but I’ve been using these types of saddles for a couple of years now and they are way more comfortable than regular ones.

The main positive for me is not having the nose of the regular saddles between my legs, if feels “free-er”, less rubbing.

its a dumb trend. having a shorter rail means the amount of saddle that flexes with your weight is shorter, which in turn means the part that flexes doesn’t include under your taint. so your sit bones have flexing, suspended saddle shell under them, but your taint just has the rail attachment under it. also gives you less to steer with your thighs with.

Cool! You’ve managed to accomplish what no one else in cycling has ever been able to do: know what saddle works best for riders without even seeing or talking to them!

Then.. tell me why so many bike fitters reccomend them? Tell me why I went from a Prologo Zero to a Speshy Power and I’m never going back to a traditional saddle due to the increased comfort of the “snub-nosed” saddle shape? I have both the Sworks and the base Power saddle, and my sit bones sure as hel don’t flex.

If a traditional saddle works for you then that’s wonderful, but don’t allow your ignorance to denigrate something that actually helps a lot of cyclists. Not everyone is a tiny arsed jockey, and some of us are tall and have sprinter’s glutes and thighs. Don’t need them rubbing all over the long nose of a more traditional saddle, thanks.

The negatives your comment are unfounded.
You’re right about how they came to be. Shorter saddles are inherently lighter so that becomes a selling point as well. Sure it works for some, but they probably don’t know what they’re missing either.

Thanks for still making a white cover!

“245x143mm, now available in one size only”
I’m assuming this means they’re going back to a one (small) size fits all approach? Really? I guess they enjoy losing market share to Speshy and Shimano, who both offer 155mm+ saddles.

perhaps 155mm was 1% of their sales, so why keep it?
