At Swim-Two-Birds

October 23, 2023

I’ve been to the library more in the past week than I have in the past 3 years. I’ve also silkscreened more chainrings onto postcards in the past week than I ever have before. Most of my cranks are 130 bcd but these old LX cranks are 110. Chainring bolts and their bolt circle diameters have crawled into my subconscious mind and Flann O’Brien is getting in there too  


Had a dream that I was at the library, checking out a few more books. I started to unlock my bike and noticed the chainring dangling from the crank and the chain slack on the ground.  Everything else seemed to be there as I wondered why someone would take the time to steal 5 short-stack chainring bolts off a bike but leave everything else. Rolling into some dystopian state where chainring bolts became the catalytic converter of bike theft. 


Toggling in and out of dreamland I scrolled through ways to slow a chainring bolt thief. Variations on the theme of tamper proof security fasteners. There’s a tool for that. Numerous choices exist in the industrial fastener world. Several choices exist in the bike bolt world to protect your wheels, pedals, saddle and seatpost. But none of them are chainring bolts. 


What if thieves were not after your saddle or wheels or pedals? What if thieves just wanted the bolts that hold it all together? Especially the chainring bolts.

The SLX FC-M7100-1 crank features an entirely new construction, using direct mount chainrings with special bolts designed to piss you off
