    Upgrading rotor size

    Sorry, I've searched but can't find this. Can someone please inform about how to install larger rotor on Hayes HFX 9 XC that came stock with my Giant Trance X1. I'm new to this so pardon in advance. I don't know whether mine are IS or Post. I'd love any pics to distinguish the two types. I believe if post, I just need an adapter bracket.

    Your fork probably uses an IS mount from what i can see. Youd need an IS adapter for the larger rotor. If you are upgrading just the rotor, than you need to get the adapter, if you are buying the brakes as well, than itll come with the adapter.
