Double Or Nuthin Posted February 9, 2004 Report Share Posted February 9, 2004 I have a used Cool Head. The domes are shot. My question is? Which domes are right for me?

If I was at 4,000 or 5,000, I'd probably run 19cc. The higher elevation you go, the less compression, so the smaller dome will bring your compression back up. Tell us your elevation, and we'll get you a good answer. Quote Link to comment Share on other sites More sharing options...
