I've been going over my Genesis Onyx 29 before riding it and to work all the bugs out before motorizing it. All the warnings about dry bearings and loose spokes are not exaggerations. In the process, I've discovered how lacking my tool collection is for working on bicycles. Since the bike is new, I don't want to chew up the fasteners with the wrong tools, but I also don't want to wait for them to get here from Amazon, or Ebay. What I discovered is that a castle nut makes a pretty good spoke wrench. Now if I could just find a good substitute for a cone wrench. I looked through all my saved motorcycle tool kits for a thin stamped steel 15mm box end and came up wanting. My LBS doesn't sell them and they were out of spoke wrenches. Also, everything I can find online about this bike says it's a threadless headtube design, but it has a big hex nut on it with a normal looking sliding wedge handlebar stem. Does anyone here know ? I'm kinda fugnorant on bicycle stuff.
