    Ordered a black 49, let me know if there’s any plans to do more purples though… Got a good candidate for dat anodize.

    • John Watson

      The purple rings were special – we won’t do them again…

      • Malaysian

        Not even one?

        Would set off so good against the decals…

        • Noel Smith

          Sorry, only for superstar bloggers

          • Ryan Combdon

            More like the talented people that won the photo contest.

          • John Watson

            Actually, I gave them all away to people who won that photo contest I threw…

          • Malaysian

            Fair enough, can’t blame a guy for trying.

    • FF

      You should’ve ordered a silver one and have it anodized somewhere.

  • Jason

    Will the omnium chain bolts work with these?

    • Robert

      Yes, the Omnium has a BCD of 144mm, like this chainring.

      • Jason

        I should have been more specific. The omnium chainring is 5mm thick and there have been problems using the stock chain ring bolts with aftermarket chain rings because of slack between the bolts and chainring.

        • John Watson

          I use them on my FBM with no problem

  • stickone

      • Malaysian

        Maybe too late but any chance of doing same for mine to the UK?

        • John Watson

          I usually do that for all international orders.

          • Malaysian

            Great, thanks. Didn’t want to ask.

          • Kamal Balgobin

            So this will be done to all order to the UK? if so that would be great :)

  • Art Vandal

    Can I make a change in the order of 47 to 49?

  • Malcolm T

    Anyone have a pic of what they look like on C-recod cranks?

  • george91

    Order placed, hopefully its still in stock! I was gutted when I missed the last batch.

    • John Watson

      They’re still in stock! We made a couple hundred!

  • Art Vandal

    Hi! You got my e-mail with a request to replace 47 to 49? I have not received a response.

  • luketango
