    Unfamiliar bike terminology

    I'm currently looking at the axiom odyssee rear suspension rack, but I don't understand the terminology. The website states:


    "Fits most 4 bar “Horst-Link” and “URT” suspension designs - Not compatible with - “seatstay dropout pivot” - 4 bar linkage bikes"

    Specifically: How do I know if my suspension is Horst-Link or URT? What is a seatstay dropout pivot / 4 bar linkage?

    Thanks for any help you can give.

    This is a 4 bar suspension:

    The 'Horst Link' is the pivots at the back of the chain stay, it allows the suspension to travel freely even when the rear brake is applied.


    Dropouts are usually defines as where your wheel connects to the rest of your bike. The seat stay is the part of the fram that goes from the seat to the end of the chain stays.

    Here's a picture of the seat stay dropout:


    The difference is pretty subtle, I hope this helps.

    Thanks for your kind help. My RS looks nothing like the ones in the picture, so I may be out of luck with the Axiom rack. Thanks again.
