Infinity Bike Seat

Hey my beautiful bike nerds, has anyone tried the Infinity Bike Seat? I’m really intrigued by its shape, and I’ve seen they have ambassadors who ride a lot of kilometers. The downsides I’ve read are their return policy, high price, and poor customer service.

Thanks for the help!

Does not look like it would suit my personal anatomy. A specific concern would be lack of comfort if moving even a centimetre or so forward from “optimal” positioning … But hey, your experience may differ !

I was able to try one before buying, because a bike shop local to me - Handy Bikes in Alexandria, VA - is one of the few places that offer demo. I’m glad I did, because it turned out that it really didn’t work for me.

(I also found it impossible to understand from the website how the various models were similar vs different, beyond the visually obvious that some models are open in the middle. Pete at Handy Bikes explained it to me, but I don’t remember the details.)

What are these actually supposed to achieve? I can’t wrap my head around how these are supposed to be a good idea

Oh, dear. I’m worried that seat photo is going to set off some filters at my workplace and get me dragged into HR.

Is it designed to destroy your perineum until you sit on it right? Like the Aeron of bike saddles?

There are also versions that are closed in the middle.

There are people who ride a lot who swear by these saddles. I wanted to try last year when I was experiencing pain in my perineal area that I thought might be saddle-related.

I’m 100% for whatever options work for people to be able to ride comfortably, and so good on the inventors of Infinity for their innovation. I do wish that they were able to run their business in a more customer-friendly way.

In my case, Infinity saddles weren’t comfortable (and whatever I was experiencing could be addressed in other ways).

I know a handful of ultra-distance (e.g. RAAM/RAW) riders and triathletes who swear by their Infinity Saddles. If that’s what their anatomies find ideal, so be it.

When I tried one a few years back it was suboptimal for my own anatomy and preferred riding position.

Great LBS! They’ve always done excellent work as promised for myself and friends I’ve steered their way.

What I have seen/heard;

Very Expensive

Horrible customer service

Horrible dealer support

Love it or Hate it. The people who love them, LOVE them, and the people they don’t work absolutely despise them.

Funnily enough, the person I know who absolutely swears by them, says she wishes she hated the thing because of all the first three.

I wasn’t able to get on with the model in the picture which I believe is the NX series. The part under the sit bones was too hard for me. I wrapped that area with bar tape which helped a little but still too hard.

However, the EX1 was a game changer for me. I’m the “Imelda Marcos” of saddles and would conservatively estimate I’ve spent upwards of $10k on saddles over the last 30 years. I put the EX1 on and did a 400k on it the next day - perfect. I’ve done numerous 1200k+ rides since then including PBP and LEL and have been completely, totally, 100% pain free. No saddle sores, no chafing, nothing.

I will say though that I’ve found them to be very finicky wrt positioning. 2mm too far forward or back or 1-2 degrees too much or too little seat angle really matters with these saddles, more than any other I’ve tried.

I’ll say further that they don’t work for everybody. I talked a friend who is also a long distance cyclist into buying one and he just didn’t get on with it. I ended up buying it from him.

As always, YMMV.

Hello, another strong Infinity advocate and ultra-distance rider here to weigh in :sweat_smile:

For me, the Infinity E2 completely transformed my comfort on multi day rides. Since I bought one a few years back I haven’t experienced any saddle sores even on very long trips/events. So it works extremely well for me.

in terms of describing what it’s like:

  • The biggest change is that your sit bones aren’t resting on anything. So sit bone pain will disappear overnight.
  • Your weight tends to be supported mostly by the side rails, which the back of your legs lightly rest on. It takes a couple of rides to get used to this sensation but didn’t cause me any issues.
  • You can change the feel a lot by changing the tilt of the saddle. I started with the rails level (gave a feeling of being in a hammock) and have now tilted mine forward a little. Infact I find that this saddle really helps to rotate my hips forward more than anything else I’ve used. I think this has helped me to improve my position a lot and reduced back pain.
  • Because your weight is supported quite wide, the height you need this saddle seems to be a bit lower than others. I have mine about 1cm lower than I would a normal saddle to achieve the same fit.
  • It works very well for me for perinium issues. I can sit in tri bars for a long time without getting any discomfort or numbness.
  • I find there’s actually several ways I can sit on mine in comfort (I.e. sliding forward/back a bit) and I make use of this on long rides.
  • One limitation is the max sit bone width of 13cm. I do wish they’d make a wider model to make it more universally fittable.
  • I’ve been fortunate to try a couple of models and I think the simple E2 is the best one for me. I don’t see the point in the E3 tbh.
  • Finally. DO NOT under any circumstances buy the carbon rail version! They will snap.

I think the USP is that your sit bones aren’t supported by anything, so sit bone pain is no longer an issue. Your weight is supported more towards the outside rails of the saddle

I was chatting with someone who said “you sit in the saddle instead of on it.”

My partner picked one up so I’ll probably steal it for a test ride or two.

Despite the odd shape this looks ergonomically like it would work a lot like a leather Brooks saddle.
