Cantitoe Road’s concept BioFloat takes an entirely different approach to isolating the rider from vibrations and small bumps.

The BioFloat seatpost uses a clamshell elastomer to trap the saddle rail clamp, completely separating it from the alloy outer clamp. This not only diffuses vibrations and shocks, it provides 360º of “float” for the saddle, letting it truly move with you as you pedal. The elastomers are stiff enough to keep the seat in place, but the package combines the benefits of saddles with flexible shells and unidirectional seatposts like the Cirrus Body Float. The amount of flex can be adjusted by using firmer or softer elastomers.

Word is it’ll be around 245g with a target retail of $200 if and when they go into production.


  1. Unfortunate company name, however – paired with an oddball saddle mount concept I immediately pictured awkward crotch-shots…

    Look, I’ve got cantitoe!

    Don’t get me wrong – I do like the idea.

  2. I rode this seatpost (under a different name) about 5-6 years ago
    Not bad but the floating, tipping and twisting effect is no bueno. Shock absorbtion should not be combined with twisty, floating effects. Climbing on the nose of the saddle with this seatpost is pretty scary

  3. Mountain bikers have been buying this unique feature for years….only they call it a dropper post. Only roadies would flock to what others consider a design flaw

  4. The elastomer to kill road buzz looks good but float seems less good. The one time I rode a bike with a suspension stem was disconcerting and the when I push against the saddle nose with my leg I want the bike to move, not the saddle.

  5. I like the idea of limiting vibrations for the obvious reason and slight yaw movement wouldn’t be bad if one has a tendency to twist the hips while pedaling (not rocking the hips). However, I don’t like the ideas of allowing for pitching and rolling. To me, if someone has a need for either they probably have a saddle/ fit issues.

    I know they’ll be offering harder and softer elastomers, but how many different hardnesses? Elastomers made to do two of the four features would be interesting.

  6. A pretty simple and effective suspension system has been already invented over 100 years ago by Dunlop and comes free with every bike. Set up CORRECTLY it deals very effectively with the road buzz 😉

  7. Have a long elastomer washer along saddle bars and redesign clamping mechanism in alloy should eliminate pitch and roll.

What do you think?
