I was supposed.to finish the tandem super build today. King hubs to sl23 wheels came out great. Made schwalbe Dureme 35mm tires tubeless easily. This bike will be lighter than most of your mountain bikes.
Problem came when I realized both bottom brackets are 73mm, not 68. I tried to make what I had work, but still couldn't get the chainring on the stoker to clear the chainstay....stay tuned for pictures.
