Hey, my ss is finally rideable (been building it up for a while now), and the shop convinced me to buy a gussett spacer kit. I know I should not use a dx cog on a king alu body. I am not using my king wheels yet since they are not built and wont be for a few weeks, but I want to make sure I will be able to use the kit with the king wheel. I can fit both dx cogs that came with the kit on next to eachother, so my question is, is it wide enough to run a boone or endless cog? I plan to run dx on this wheel untill I know what my gearing is, then order a boone for the king which should be done by then. How wide exactly is a boone cog and how wide is a dx? Thanks for any input.
