This parallelogram seatpost suspension
could it be any good for unicycles? The suspension doesn't work linear with the seatpost, instead it moves the saddle slightly backwards. Allegedly the SR Suntour parallelogram suspension system doesn't decrease the distance between saddle and pedals. http://www.srsuntour-cycling.com/standard.xml?vpID=168 -- goldenchicken II - There is more to cycling Olaf Johansson ------------------------------------------------------------------------ goldenchicken II's Profile: http://www.unicyclist.com/profile/10248 View this thread: http://www.unicyclist.com/thread/42401 |

Looks like a more compact version of the Thudbuster post available at Unicycle.com. I don't think the angular movement is a plus for a unicycle, but it still works (moving the frame forward a bit as it compresses). -- johnfoss - More Moab Fun John Foss, the Uni-Cyclone "jfoss" at "unicycling.com" -- www.unicycling.com "Read the rules!" -- 'IUF Rulebook' (http://www.unicycling.org/iuf/rulebook/) -- 'USA Rulebook' (http://www.unicycling.org/usa/competition/) ------------------------------------------------------------------------ johnfoss's Profile: http://www.unicyclist.com/profile/832 View this thread: http://www.unicyclist.com/thread/42401 |

I had a Thudbuster and it was like a rigid seat post. I was in contact with designer and he said it relied on pivoting around the front axle of a bike. A uni doesn't pivot, it just goes up and down. It looked good though but did not allow much room for seat adjustment. Consequently it has been replaced and gone to my old Pashley which is made up of "great things" that I don't think are that great. This also includes the nice looking, but super flexible Black Widow cranks. -- onebyone Bill Blogs is an alien! www.municycle.com.au ------------------------------------------------------------------------ onebyone's Profile: http://www.unicyclist.com/profile/10014 View this thread: http://www.unicyclist.com/thread/42401 |

A better idea for suspension is to make the Pantour hub work on a unicycle. Just don't ask me how. http://www.kinetics.org.uk/html/pantour_hubs.shtml -- goldenchicken II - There is more to cycling Olaf Johansson ------------------------------------------------------------------------ goldenchicken II's Profile: http://www.unicyclist.com/profile/10248 View this thread: http://www.unicyclist.com/thread/42401 |

That Pantour hub looks really cool! For a front wheel. I think the design concept precludes running a drivetrain through it. That would probably require some sort of different approach... -- johnfoss - More Moab Fun John Foss, the Uni-Cyclone "jfoss" at "unicycling.com" -- www.unicycling.com "Read the rules!" -- 'IUF Rulebook' (http://www.unicycling.org/iuf/rulebook/) -- 'USA Rulebook' (http://www.unicycling.org/usa/competition/) ------------------------------------------------------------------------ johnfoss's Profile: http://www.unicyclist.com/profile/832 View this thread: http://www.unicyclist.com/thread/42401 |

I don't see how brakes would work (rim or disc) with a moving hub like this either. Looks like it would be impossible to keep the rim/disc in the caliper.
