tommy – you don’t really need a dedicated chainring for 1×9. I just removed the inner and outer rings from my Shimano cranks and made do with the 32T. Add a superstar xcr bb mount chain guide for £16 and it was fine. There was a little bit of rub running 32 front to 11t sprocket but bearable. I ran 32 x 32-11 on my C456. Now I’m running 34 x 36-11 (10 spd) on the full suss, just to get a marginally wider gear range (top and bottom)
If you really do want a dedicated front ring, then there are FSA ones on ebay for less than £20 depending on size. Which is generally cheaper than e-thirteen, Hope etc.
