           | My quick story: I built up an old 90s cyclocross bike and his
           | website was the main reason I have this beast of a
           | frankenbike gravel bike. I found his article "8 of 9 on 7"
           | and it changed my life: Take a 9 gear cog, remove one, and it
           | fits perfectly on a 7-speed cassette body.
           | 
           | Then I found his other article on an alternate wiring for a
           | shimano mountain bike RD-310 7/8 speed drive train (which
           | unlocks 9-speed ability), which thus let me use the rugged
           | 7/8-speed derailleur for the cassette WITH shimano dura-ace
           | indexed bar-end shifters (which use, get this, 9-speed
           | spacing on an 8-speed index because it made their system
           | "proprietary"). All of this works together flawlessly <3 <3

         | 
         | I got into building and fixing bikes around 2004, and built a

         |
