Many years ago I had the nds side of a nutted crankset loosen up while in the middle of a long ride. I managed to pedal mostly one legged to an Autozone where I begged to borrow a 14mm socket and ratchet – tightened things up enough that the crank stayed on until I replaced it months later.
I sorta didn’t learn my lesson with that experience though. The next year I had the same thing happen on a different bike – I had put a tiny ratchet and 14mm socket in my saddlebag but the cranks I was riding were 8mm hex fixing bolt. I was so ready, had the bike locked into a stop sign and my tools all laid out when I went to tighten the fixing bolt and felt like my brain missed a shift on seeing the 8mm hex. I was training for my first century and was several miles between towns in the rolling green veldt between Atlanta and Athens, GA. No cellphone signal, the only businesses I had passed had been abandoned service stations and I hadn’t seen a house in a while.
I had a cheap performance bike brand multi-tool but it only had 6mm hex, I fussed around with different combinations of jamming the tool into the 8mm opening but couldn’t get good torque. Eventually I realized I could jam everything together using the 6mm and a bunch of tiny pieces of gravel. It worked well enough to get me home wherein I bought a torque wrench and have not had any issue since then.
Lately I’ve been having issues with the NiMH batteries in my lights failing. I was out riding around south of Dallas Georgia where there’s pretty much nothing. Late autumn makes for long and very beautiful sunsets in this part of the state. As it gets darker I’m rolling along and switch on one of my two headlights – get a very dim beam. Hmm I had just taken the batteries off the charger 3 hours earlier before I left. I make the incorrect assumption that the batteries are bad and have self-discharged in the short time off-charger and unused.
I try my other light and it’s the same thing. Well hell now I have to try to ride the next 4 hours with minimal or no front lights. My rear lights are fine so I decide to just keep going with my weak, ineffectual front lights. After about half an hour the lights suddenly flip to full brightness. I’m scratching my head here but that’s fine with me I guess. I make it home and after some reading it seems the cold weather affects the batteries and reduces the ability to output high-draw power. Running them in low mode allowed the internal resistance to heat up the cell enough to start putting out the higher pull for my lights to go into high mode. I could have done the same thing by putting the cells next to my body and heating them that way.
This is my third fall/winter season on these batteries and I had not had this problem previously so it seems to be an age/quality issue. I replaced with better batteries and added some lithium batteries as backups as well as another light, just in case.
Once I had the pedal eye of a FSA Vero Cross crack 8 miles into a planned 130 mile ride. It was a stressful, mostly one-legged ride back to my car and then a wasted day getting it fixed before bailing halfway through the ride.
Other than that I’ve only really had spokes and three frames cracking but those were closer to home and although stressful, fairly simple rides back.
