    Bicycle Fabrications 2D suspension

    Anyone seen this? Looks like it can move backwards on square hits, as well as in an arc.

    It will be interesting to see how it progresses, if it turns out to be a really effective system you can bet you'll see other manufacturers licensing the system. High-Five to the little guy for coming up with something new!

    Very interesting!

    Broadly similar to the system used by Decathlon and Yeti, but using an elastomer to push the concentric pivot back into place, rather than chain tension. I hope they give you spares.

    More importantly, the nicest looking steel frame since the Silencer.

    Meh for the suspension.

    Sweet steel frame. What is the tape measure on the downtube for?

    Somwhere, they mention the only thing similar of this frame with the Yeti and Ibis is that they use eccentric links. They rotate in different directions and with different purposes.

    Seems like you would activate the rear axle path and elastomer with sag... so unless the square edge bump is a brake bump, I don't see the design working to it's intended purpose. If you hit a square edge bump over the surface, the elastomer is doing nothing.

    Agreed.

    Did you read the article...it was pretty specific about what angle of impact would activate the eccentric pivot and sag was not one of them. Also if you watch the first video he openly admits the system will feel crappy in the parking lot because it is designed around high speed DH runs.

    My only question is that...didn't Maverick already have an up and back design with the Mono-Pivot?

    Yes I read the article.

    Maybe the animation is misleading, but I guess that with your own weight you may be able to activate the elastomer as well, dunno..

    I personally dont see this going anywhere. The idea is good in theory, but I dont see it working well in the real world.

    I like that they are trying new things though,

    I bet that elastomer is pretty hard. It would need to be to keep chain tension from varying wildly over chatter and other small hits. It only comes in to play on big, square edges that try to hang up the wheel. I don't think you will see it come in to play at the sag point.

    2 Dimensional Suspension

    Hello I am Hank Matheson. I am excited to share with you that I along with my good friend Jon Heim have been granted a patent on a new rear suspension system.

    Have fun out there.

    Sincerely,

    Hank Matheson

    There is a copy of the press release below:


    Two-Dimensional Suspension Patent Awarded

    Patent #9,908,583

    April 5th, 2018 Grass Valley, CA

    A new Two-Dimensional Bicycle Rear Suspension System has been granted U.S. Patent #9,908,583. In development by Hank Matheson and Jon Heim since 2010, this suspension system combines independent vertical and rearward axle paths. The axle path changes depending on the direction of the hit to the rear wheel. This allows the axle path to conform to the force vector traveling through the axle.

    Hank Matheson mentioned I am happy to have been granted this patent and to have been able to work with Jon. I am also excited to ride the thing.

    Jon Heim said, "When Hank showed me the CandyMan(tm) prototype I thought he should apply for a patent. I was impressed with how simple and compact it was for 2-D suspension. We came up with additional configurations like the MissingLink(tm), a 2-D link that slides instead of pivots and is almost hidden. It's nice to get validation from the US Patent Office."

    Just because you can doesn't mean you should.

    Interesting but not excited. They are showing it on downhill bikes, many of which already have a great deal of rearward axle path. While some see rearward axle paths as the holy grail of downhill suspension, there are bikes that are well liked and competitive on the worldcup circuit that have as much rearward axle travel as this and others with virtually none.
