• It’s the width of the back plate that is the issue as it occupies the same space that the edge of the WRP spider does- and therefore jams it solid.

  • Any idea what chain guide the chap from WRP is using?

    I briefly ran my dh bike single speed without a chain guide and just relied on the narrow wide ring taking care of it. I felt like it was working surprisingly well right up until the chain came off twice on the same day that both got me close to a brown underpants moment. Wouldn’t run my dh bike without now.

    The chap at Cascade Components is very sound and replied to my questions on Instagram very quickly. It’s probably an extreme way to go but you could maybe ask him to machine a sub 4mm backplate for you.
    Edit - just realised the cascade one is 32t max

    Obvs the shimano guide could be worth a try but they are a bit ugly.
