Machine off the bottler opener ridges from a Surly Tuggnut and it makes an elegant chain tensioner. As Mark said,
Don’t believe in putting bottle openers on the ass end of a bike, stupid.
So he removed them and put a modified Tuggnut on the Redline SSCX yesterday, replacing the one without a thumbscrew that he didn’t like.
