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.
