I picked up a Surly Cross Check frame on Craig's List that I'm planning to build up as a commuter. I'm thinking about upgrading the headset on my Seven Axiom from a Cane Creek S3 to a Chris King and re-using the Cane Creek headset on the Cross Check. The Seven is only about 7 months old (1500 miles or so). Is it worth it to upgrade to a Chris King, or should I just keep the Cane Creek on the Seven, and install a comparable headset on the Cross Check? They're both 1 1/8".
