Feedback on new suspension seatpost
Quote | Reply
My partner and I have developed a new suspension seatpost that addresses most of the current limitations of units on the market. We have received phenomenal feedback from anyone who's ridden it. Local cyclocross riders, roadies, mtn bikers, reviewers, doctors, chiropractors...and the like. I'm curious on any feedback you might have, and in particular, any ideas on how to design a test with power to evaluate it's use for cyclocross, triathlon and other applications. Units are not for sale yet but we are actively testing, riding and giving these things all the punishment possible. http://www.cirrusbodyfloat.com. looking forward to some critical and useful feedback... Slowtwitch comes highly recommended. Please contact us via the site if you are interested to learn more.

Looks interesting, congratulations on your efforts. It looks to have a fair bit of set back, What is the off-set? Is it reversible? The For/Aft needs for most triathletes and some road riding applications the noise of the saddle ends up be close to if not beyond the center of the BB in a parallel line. additionally saddles tend to maximize their own sense of suspension and rider safety from a centralized position on the clamp. Personally I am a bit of a "Forward Thinking" fitter/frame designer and tend to employ a healthy For/Aft relative to the application, needs, and functional movement of the individual rider while following the natural flow of the human animal.

To answer your question, You may receive deceptive feedback from your test (not in a good way) if you were to test power compared to a standard post on a Tri-bike as I believe you will not be able to put most triathletes in the same place in space with your post as they are with their current configuration that you would be testing against, this is do to the forward nature of a proper Tri position.

Use of an ISM Adamo saddle may help as it is a no noise saddle with a lot more for/aft variability than most, no to mention with this design, on a steep angled tri bike, the saddle tends to end up closer to the front of the saddle rails so with your increased set back moving the ISM to its max line in the forward position may put your rider closer if not in the same place in space. any deviation from this will not result in an apple to apple test

An additional issue you may find is that many if not most of the new tri bikes made today utilize proprietary "aero" seat posts and masts.

Good luck with your project.

I feel like the fact that this is a round seatpost is a dealbreaker in triathlon- no modern bike will take this kind of seat post...if i were useing it for tri i would make it as an adapter that fits between the seatpost clamp and the real seatpost...

Clyde_s_dale,
We have to enter the market with a standard post to get the ball rolling. We are building a topper system that will work with masts, aero posts and such, the final on that will be early next year. We will focus a lot of effort on the tri/endurance market in the coming months and throughout our development process. We are currently starting to work with some incredible riders that will be beta-testing and performance testing for us in upcoming national endurance events. Riders whom ride mast/posts that have ridden the BodyFloat have switched to their standard seat post bike set-ups because of the realized benefits and features of the BodyFloat. There are a lot of proprietary system out there to work with...we are just getting started. Check out our Kickstarter campaign for some more info on it. (http://www.kickstarter.com/projects/188418586/bodyfloattm-an-evolution-in-bicycle-comfort-and-pe).


Thanks for the note. The BodyFloat is a game-changer up there with the Softride/TitanFlex/Zipp days of old. Keep in touch. Cheers, Charlie

dont get me wrong- i LOVE the idea for a road bike. I just know a lot of triathletes (i coach) and they would never part with their carbon fiber aero bikes- this crowd is just too aero-weenie to change bikes for a more comfrotable ride.

I would put one on my road bike in a second though!

ya...that is the common response. We are wanting to work with coaches on this in a big way. the benefits of the system outweigh the aero benefits...but that takes some quantified testing results. Best of both would be ideal. And yes, it improves comfort dramatically but also dramatically improves performance due to the more comfortable ride. The bio-mechanical advantage of less fatigue, less pressure points, less vibrations entering the body, etc. Fit & tune-ability are key benefits of the BodyFloat. With the adjustable sweet spot, the rider (or coach) can dial a rider in and tune it like a formula one race car. The rider will be virtually levitated over the bike and can not feel the system working. It's pretty cool how it works. We have a booth at Interbike if you're in Vegas this week...or have some friends that can come and check it out. cph
